Step-by-step explanation:

When the lines intersect, the point of intersection is the only point that the two graphs have in common. So the coordinates of that point are the solution for the two variables used in the equations.

a linear equation is an equation in which the highest order of exponent is 1.

your equation is:

4x - y = 7

it's a linear equation.

none of the variables has an exponent larger than 1.

x = x^1

y = y^1

to find your ordered pairs, just take 3 values for x at random and plug them into the equation.

let x = 1,2,3

your equation is:

4x - y = 7

if you solve for y, it makes it easier to find the y value given the x value.

solve for y to get:

y = 4x - 7

when x = 1, y = -3

when x = 2, y = 1

when x = 3, y = 5

placing the equation into this form also allows you to graph it.

placing the equation into this form also gives you the slope-intercept form of the equation.

what you started with was the standard form of the equation for a straight line.

that standard form is ax + by = c

your equation is:

4x - y = 7

a = 4 and b = -1

the slope intercept form of the equation of a straight line is y = mx + b

m is the slope and b is the y intercept.

when you solved for y, you placed the equation into this form.

your slope is 4

your y intercept is -7

graph of your equation looks like this:

I placed horizontal lines at y = -3, 1, 5.

If you trace a vertical line down from the intersections of those lines with the line created by your equation, you will see that the value of x at those intersection points is 1,2,3

the points on the line formed by your equation are:

(x1,y1) = (1,-3)

(x2,y2) = (2,1)

(x3,y3) = (3,5)

you can take any other values of x and find the corresponding value of y by just replacing x in the equation with the value of x.

the equation is y = 4x - 7

when x = 5, y = 20-7 = 13, etc. brainlest pls

Answer:

0.6341 = 63.41% probability that his commute today took more than 35 minutes

Step-by-step explanation:

Randomly distributed = Uniform distribution.

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value higher than x is given by:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

Randomly distributed with a minimum of 20 minutes, a maximum of 61 minutes.

This means that [tex]a = 20, b = 61[/tex].

What is the probability that his commute today took more than 35 minutes?

[tex]P(X > 35) = \frac{61 - 35}{61 - 20} = 0.6341[/tex]

0.6341 = 63.41% probability that his commute today took more than 35 minutes

Answer:

4x + 4y

Step-by-step explanation:

5y - 8x - y + 12x

4y + 4x

Answer:

4y + 4x

Step-by-step explanation:

There are 4 terms in the equation 5y - 8x - y + 12x: 5y, -8x, -y, and 12x. WE have to add like terms to make a simplified equation. 5y and -y are alike, as are -8x and 12x. Subtract 1y from 5y to get 4y. Add 12x to -8x to get +4x. As a result, the expression becomes 4y + 4x.

Step-by-step explanation:

First week of July = 1040 people

Fourth week of July = 1040- 100 + 130 - 290 = 780

The number of people that went to the swimming pool in 1st week was 1040 while the 4th week had 780. The percentage decrease will be:

= (1040 - 780) / 1040 × 100

= (260 / 1040) × 100

= 0.25 × 100

Answer:

length = 100< l > 150

breadth = 50 < b> 100

Step-by-step explanation:

The area of the rectangle is given by the formula

Area= Length * Breadth

A= L*B

Suppose both the length and the breadth are 100 feet then the area would become

A= 100*100= 10,000 square feet.

The length and the breadth of the square are equal in size and we dont need a square we need a rectangle therefore these values cannot be inclusive for lenght and breadth.

It is given that the length is longer than 100 feet and breadth is shorter than 100 feet.Therefore

length can be 110 feet and breadth 90 feet

Again the area = A= l*b = 110 *90= 9,900 square feet.

Similarly putting different value from 50 to 150 feet for breadth and length we can obtain different results .

Area = l*b = 150*50 = 7500 square feet

for all values of the length between 100 to 150 feet and for breadth 50- 100 feet we can have the values of the area between 7500 to 10,000 square feet.

length = 100< l > 150

breadth = 50 < b> 100

Given :

A T.V. is measure by its diagonal.

To Find :

If the height of a 60 inch  T.V. is 32 inches, what is the width.

Solution :

We know, T.V. is rectangular in shape and angle between two sides of rectangular is 90° .

Let, width of T.V. is x.

Applying Pythagoras theorem in sides, we get :

[tex]height^2 + width^2 = hypotenuse^2\\\\23^2 + x^2 = 60^2\\\\x = \sqrt{3600 -529 }\\\\x = 55.42 \ inches[/tex]

The value of the expression 2x/3 ÷ 3x/2 when x ≠ 0 is 4/9.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

2x/3 ÷ 3x/2 when x ≠ 0.

This can be written as,

= (2x/3) x (2/3x)

= 2/3 x 2/3

= 4/9

Thus,

The value of the expression is 4/9.

Answer:

  x = 33°

Step-by-step explanation:

The value of an inscribed angle is half the value of the arc it subtends.

The angle marked x subtends the arc marked 66°, so has a value of ...

  x = 66°/2

  x = 33°

_____

The value of y is similarly found.

  y = 96°/2

  y = 48°

__

The angle marked with a dot is an external angle of the triangle, so is the sum of the remote internal angles, x and y:

  dot angle = x + y = 33° +48° = 81°

Of course, angle z is the supplement of this:

  z = 180° -81°

  z = 99°

Step-by-step explanation:

First, you can change the equation to 12 1/2 + 4 1/2, as subtracting a negative number is actually adding it. Then, if easier, the mixed numbers can be changed to improper fractions -- 12 1/2 = 25/2 and 4 1/2 = 9/2. Then add; 25/2 + 9/2 = 34/2, and 34 divided by 2 is 17.

Answer:

y = 4x + 3

Step-by-step explanation:

Step 1: Write the general equation

y = mx + b

Step 2: Identify b, the Y intercept (x = 0)

b is the value of y when x = 0.

From the graph, when x = 0, y = 3.

Therefore, b = 3

Step 3: The second point from graph (x, y):

P = (1, 7)

Step 4: Define m as ratio of rise / run:

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Step 5: Put coordinates into ratio:

Using the two coordinates, (0, 3) and (1, 7), we would have,

[tex] m = \frac{7 - 3}{1 - 0} [/tex]

Step 6: Perform subtraction to get slope:

[tex] m = \frac{4}{1} [/tex]

m = 4

Step 7: Substitute values into y = mx + b:

Thus, plug in the values of m and b into the slope-intercept equation.

b = 3, m = 4, therefore:

y = (4)x + (3)

Step 8: Write answer:

y = 4x + 3
