Answer:

  (0, -3)

Step-by-step explanation:

You want a point on the graph of 4x -y = 3.

It is often convenient to choose an intercept when looking for a point that will satisfy the equation. Here, it is convenient to set x=0 to obtain y=-3.

A solution ordered pair is (0, -3).

Additional comment

Here, it will be more convenient to choose a value for x. Choosing a value for y can result in fractions becoming involved for the values of x. We prefer to avoid that.

  y = 4x -3 . . . . . . y=-3 when x=0; y=1 when x=1, so (1, 1) is another solution

Answer: 25%

Step-by-step explanation:

The number of seats in the two buses are: first bus includes 27 seats and second bus includes 108 seats.

An equation known as proportion shows that the two ratios presented are equal to one another. For instance, the time it takes a train to go 100 kilometres per hour is equal to the time it needs to travel 500 kilometres in five hours. Example: 100 km/hr = 500 km/5 hour.

Given that:

Three rows of nine seats each make up one bus, hence the first bus's seating arrangement is as follows:

3 x 9 = 27.

Since the other bus has four times as many seats as the first bus, the second bus's seat count is as follows:

4 x 27 = 108.

Hence, the number in the two buses are first bus includes 27 seats and second bus includes 108 seats.

The production of congruent figures involves stiff rigid transformation Even if you could imagine them as forms that "appear exactly the same," congruent figures.

During accurate modification of a geometric object, distance between each point pair is maintained. In other words, precise transformations maintain an object's size and shape. For instance, the angles and lengths of a triangle are preserved throughout a rigid transformation. Imagine a stiff shape, such as one made of cardboard, distorting. Even when the shape is rotated, mirrored, and moved left and right, nothing changes.

Here,

When I used putty to create a mold, it was the opposite. After that, users can stretch and twist the objects.

These ratios are not exact though. The distance between every pair of points is altered when the shape is stretched.

Applying rotations, reflection, and translations—three different forms of transformations—can result in congruent shapes.

In reality, by mixing any or all of these three transformations, any congruent shape pairs can be matched to one another.

Day 1: 8 pairs x $5.00/pair = $40.00

Day 2: 7 pairs x $5.00/pair = $35.00

Day 3: 15 pairs x $5.00/pair = $75.00

Day 4: 12 pairs x $5.00/pair = $60.00

Day 5: 31 pairs x $5.00/pair = $155.00

Day 6: 20 pairs x $5.00/pair = $100.00

Day 7: 35 pairs x $5.00/pair = $175.00

Total sales for the week: $40.00 + $35.00 + $75.00 + $60.00 + $155.00 + $100.00 + $175.00 = $605.00

Daily average of sales: $605.00 / 7 = $86.43

Total cost: 8 pairs + 7 pairs + 15 pairs + 12 pairs + 31 pairs + 20 pairs + 35 pairs = 128 pairs x $1.25/pair = $160.00

Profit: $605.00 - $160.00 = $445.00

So your total sales for the week were $605.00, your daily average of sales was $86.43, your total cost was $160.00 and your profit was $445.00

The area of the rectangle with a length of (x + 5) cm and width of (x + 2) cm is (x² + 7x + 10) cm²

An equation is an expression that shows the relationship between two or more numbers and variables.

A rectangle is a quadrilateral (has four sides and four angles) in which opposite sides are equal and parallel. The area of a rectangle is the amount of space that it occupies. The area is calculated using:

Area = length * width

The rectangle shown has a length of (x + 5) cm and width of (x + 2) cm. Hence:

Area = length * width

Substituting:

Area = (x + 5)(x + 2)

Area = x² + 2x + 5x + 10

Area = (x² + 7x + 10) cm²

The area of the rectangle is (x² + 7x + 10) cm²

The hypothesis is "the stars are visible".

The conclusion is "it is night".

This is because a conditional follows the format of "if hypothesis, then conclusion". It shortens to "If P, then Q".

It's fairly clear that the original conditional is true. There are some extremely rare exceptions, but mostly stars are only visible at night.

--------------------------

The converse is "If it is night, then the stars are visible".

Reason: The original "If P, then Q" format flips to "If Q, then P" when forming the converse.

The converse is false. The fact that it is night does not automatically lead to the stars being visible. For example, storm clouds at night can obscure the stars.

--------------------------

The inverse is "If the stars aren't visible, then it is not night".

We negate both the hypothesis and conclusion. The format of the inverse is "If not P, then not Q".

Like the previous statement, the inverse is false. Why? Because the stars not being visible doesn't automatically mean it's not night. We could have storm clouds covering up the stars. Or perhaps the city has a lot of light pollution to drown out the stars.

The converse and inverse have the same truth value, as they are equivalent statements (just phrased slightly different ways).

--------------------------

The contrapositive is "If it's not night, then the stars aren't visible".

The original conditional "If P, then Q" leads to the contrapositive "If not Q, then not P". We swap the positions of P and Q. Also, we negate each piece. In a sense, we combine both the inverse and converse operations to get a contrapositive.

The contrapositive is true because "not night" of course means "day", in which the stars aren't present in the sky. The contrapositive and original conditional have the same truth value. The contrapositive is a way to rephrase the original conditional.

Answer:

Hypothesis:  "the stars are visible"

Conclusion:  "it is night"

Converse:  "If it is night, then the stars are visible" - false.

Inverse:  "If the stars are not visible, then it is not night." - false.

Contrapositive:  "If it is not night, then the stars are not visible" - true.

Step-by-step explanation:

Conditional statement

"If this happens, then that will happen."

Given conditional statement:

Therefore:

Converse statement

The converse of a conditional statement is formed by switching the hypothesis and the conclusion.

Therefore, the converse of the given conditional statement is:

This is a false statement as the stars will not be visible if there is cloud cover at night.

Inverse statement

The inverse of a conditional statement is formed by negating the hypothesis and the conclusion.

Therefore, the inverse of the given conditional statement is:

This is a false statement as the stars will not be visible if there is cloud cover at night.

Contrapositive statement

The contrapositive of a conditional statement is when both the hypothesis and conclusion are negated and then switched.

Therefore, the contrapositive of the given conditional statement is:

It is difficult to say if this is a true or false statement without more information, as it is possible to see bright stars during the daytime through a telescope or a really powerful pair of binoculars.

If we are to assume that "visible" means "visible to the eye" without any magnification assistance, then the statement is true (if we exclude the sun, which is a star).

Answer:

Step-by-step explanation:

The three numbers are 50, 40, and 27.

We can solve this equation by setting up a system of equations.

Let x be the first number, y be the second number, and z be the third number.

x + y + z = 117

y = x - 10

z = (1/2)x + 2

Substituting the equation for y into the first equation, we get:

x + (x - 10) + (1/2)x + 2 = 117

2x - 8 = 117

2x = 125

x = 62.5

Substituting this value of x into the other equations, we get:

y = x - 10 = 62.5 - 10 = 52

z = (1/2)x + 2 = (1/2)62.5 + 2 = 32.5 + 2 = 34.5

Rounding these values, the three numbers are 50, 40, and 27.

The probabilities regarding the total time of the 34 jets are given as follows:

a) Less than 320 minutes: 0.9306 = 93.06%.

b) More than 275 minutes: 0.8238 = 82.38%.

c) Between 275 and 320 minutes: 0.7544 = 75.44%.

The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for the total time of the 34 jets is given as follows:

The probability that the mean is less than 320 minutes is the p-value of Z when X = 320, hence:

Z = (320 - 292.4)/18.66

Z = 1.48

Z = 1.48 has a p-value of 0.9306.

The probability that the mean is more than 275 minutes is one subtracted by the p-value of Z when X = 275, hence:

Z = (275 - 292.4)/18.66

Z = -0.93

Z = -0.93 has a p-value of 0.1762.

1 - 0.1762 = 0.8238.

The probability of a value between these two amounts is given as follows:

0.9306 - 0.1762 = 0.7544.

Answer:

To solve the simultaneous equations 3x - 2y = 4 and 4x - y = 13, we can use elimination or substitution. To solve by elimination, we can subtract 3x - 2y from both sides of the first equation, and 4x - y from both sides of the second equation, resulting in -2y = -12 and -y = 9. Then we can add the two equations together which gives us -3y = -3. Dividing both sides by -3 gives us y = 1. We can then substitute this value for y into either of the original equations and solve for x. In this case, if we substitute 1 for y in the first equation, we get 3x - 2(1) = 4, which simplifies to 3x = 6. Dividing both sides by 3 gives us x = 2. Therefore, the solution to the simultaneous equations is x = 2 and y = 1.

Take either of the equations and choose which to make the subject. i shall choose the second equation and make -y the subject of the formula.

[tex]4x - y = -13[/tex]

lets take -y to the other side because we want -y to be positive, ie (+y)

[tex]4x = y - 13 ,[/tex] take -13 to the other side,

[tex]y= 4x + 13[/tex]

now that we have that we take the other equation and substitute what y is into the equation, i.e

[tex]3x + 2( 4x + 13) = 43x + 8x + 26= 411x + 26 = 4[/tex]

we take +26 to the other side,

[tex]11x = 4 - 26[/tex]

[tex]11x = -22[/tex][tex],[/tex] divide both sides by 11, x becomes

[tex]x = -2[/tex]

now that we know what x is we substitute it into the formula,
