The standard form of a linear equation is expressed as Ax + By = C

Given the equation below;

y - 8 = 3(x+1)

Expand

y- 8 = 3x + 3

Collect the like terms

y-3x = 3 + 8

y - 3x = 11

-3x + y = 11

3x - y = -11

To order them start with the dight with the highest number in the place that isn't equal. In this case it the 4 in the hundredths place so are top 3 numbers are 0.741, 0.7412, and 0.744. As this point you continue to look at the greatest number when the dights aren't equal so the top three would be ordered 0.744,0.7412

0.744,0.7412, and 0.741. As for the bottom 2 numbers you do the same thing with the top three numbers so the rest of the list is 0.70411 and 0.7041

The following volume quantities are listed below:

a) 2 pints, 1 qt

b) 12 pints, 6 qt

c) 5 pints, 2.5 c

d) 6.75 pints, 3.375 fl oz

In this question we must transform a quantity in a unit to another quantity in a unit of the same kind. For instance, if we have a quantity in a mass unit, then we only can convert it into another mass unit.

Herein we have four unit conversion cases for volumes, both pints and quarts are volume units commonly used in the United States. There are the following equivalencies:

Now we proceed to convert each quantity to pints and quarts by cross multiplication:

a) 32 fl oz × 2 pints / 32 fl oz = 2 pints, 32 fl oz × 1 qt / 32 fl oz = 1 qt

b) 24 c × 2 pints / 4 c = 12 pints, 24 c × 1 qt / 4 c = 6 qt

c) 10 c × 2 pints / 4 c = 5 pints, 10 c × 1 qt / 4 c = 2.5 c

Brand A is better buy than that of Brand B as unit price of Brand A is 0.054 which is less than that of Brand B's unit price $0.069

Fractions represent portions of a whole or set of objects. A fraction is divided into two pieces. The numerator is the number at the top of the line. It indicates how many equal chunks of the total or collection are taken. The denominator is the number below the line. It indicates the total number of equal pieces into which the whole is divided or the total number of the same objects in a collection.

If 72 spoons is 3.89

Then 1 spoons is 3.89/72

= 0.054

If 96 spoons is $6.62

Then 1 spoons is 6.62/96

=0.069

Thus, Brand A is better buy than that of Brand B as unit price of Brand A is 0.054 which is less than that of Brand B's unit price $0.069

Answer:

x = 6 and y = 10

Step-by-step explanation:

Substract (-5x+3y=0) from (7x-4y=2)

[tex] \sf \: - 5x + 3y = 0 \\ \sf \: \: \: \: 7x - 4y = 2 \\ = = = = = = = = \\ \sf2x - 1y = 2 \\ = = = = = = = = =[/tex]

Let's solve your system by elimination.

7x−4y=2;2x−1y=2

Multiply the second equation by -4, then add the equations together.

(7x−4y=2)

−4(2x−1y=2)

Becomes:

7x−4y=2

−8x+4y=−8

Add these equations to eliminate y:

−x=−6

Then solve−x=−6for x:

−x=−6

−x/−1 = −6/−1

(Divide both sides by -1)

x=6

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

7x−4y=2

Substitute6forxin7x−4y=2:

(7)(6)−4y=2

−4y+42=2(Simplify both sides of the equation)

−4y+42+−42=2+−42(Add -42 to both sides)

−4y=−40

−4y/−4 = −40/−4

(Divide both sides by -4)

The equation of the line in standard form of 2y = -4x - 12 is 4x + 2y = -12.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant.

Given the equation 2y = -4x - 12, to write the equation in standard form, arrange the variable(s) in one side and the constant(s) in the other.

2y = -4x - 12

The equation of line is:

y = (5/2) x - 11

Given,

Points (x₁, y₁) = (2, 4) and (x₂, y₂) = (-4, -11)

We can find the slope using the equation for slope

m = (y₂ - y₁) / (x₂ - x₁)

   = (-11 -4) / (-4 -2)

   = -15 / - 6

    = 5/2

We know the slope and a point, so we can use point slope form to make an equation

y-y₁ = m(x-x₁)

y - (-4) = 5/2 (x-2)

Distribute

y+4 = 5/2x – 5/2 x 2

y+4 = 5/2x - 5

The equation of the line in point-slope form, with slope equal to -1 and passing through the point located at (-3 , 5), is (y - 5) = -1(x + 3).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Using the point slope form, plug in the values to set up the equation.

(y - y1) = m(x - x1)

where m = -1 and (x1 , y1) = (-3 , 5)

(y - 5) = -1(x - -3)

(y - 5) = -1(x + 3)

In slope-intercept form, the equation of the line is:

(y - 5) = -1(x + 3)

y - 5 = -x -3

y = -x + 2

In standard form, the equation of the line is:

The distance from the sun to the other focus is 5.01 × 10⁹ m.

(a) The distance from the center of an ellipse to a focus is an where a is the semi major axis and e is the eccentricity. Thus, the separation of the foci ( in the case of Earth's orbit ) is;

2ae = 2(1.50 × 10¹¹)(0.0167) = 5.01 × 10⁹ m.

(b) To express this in terms of solar radii, we set up a ratio;

The formula for estimating the nth term of an arithmetic sequence is:

a n = a₁ + (n-1)d

The first five terms of a n = -2n + 3 = 1, -1, -3, -5, -7

A succession of numbers merged together to make a sequence exists comprehended as an arithmetic sequence.

A series of numbers named an arithmetic progression or arithmetic sequence (AP) contains a constant difference between the terms.

The formula for estimating the nth term of an arithmetic sequence exists:

a n = a₁ + (n-1)d

The four quantities in the formula exist a n, a₁, n, d.

The first 5 terms are a n = -2n + 3

a₁ = -2 + 3 = 1

a2 = -4 + 3 = -1

a3 = -6 + 3 = -3

The maximum​ displacement, the​ frequency, and the time required for one cycle are 1/5 inch, 1/π Hz and π sec.

A displacement is a vector in geometry and mechanics that has a length equal to the shortest distance between a point P's initial and final positions. It calculates the length and angle of the net motion, or total motion, in a straight line from the starting point to the destination of the point trajectory. The translation that links the starting point and the ending point can be used to spot a displacement.

Therefore, the instantaneous speed is different from velocity, which is the rate at which the distance traveled along a particular path changes over time. The temporal rate of change of the position vector can also be used to describe velocity.

  Rationalization is a mathematical operation that allows us to determine or eliminate a root of the denominator of a fraction, so that it can be expressed in linear form, either decimal or integer, by the product of a root.

  As defined above, we must perform a mathematical operation to eliminate the root of the denominator without altering the value.

The probability that the chosen marble will be red is, 0.27.

Probability:

Probability is calculated by using the formula,

P(A) = n(A)/n(S)

Where,

P(A) is the probability of an event “A”

n(A) is the number of favorable outcomes.

n(S) is the total number of events in the sample space.

Given,

A box contains 7 blue marbles, 6 red marbles, 2 white marbles, and 3 black marbles.

Here we need to find  If one marble is chosen at random, then what is the probability that it will be red.

According to the formula,

number of favorable outcomes = 6

total number of events in the sample space = 7 + 6 + 2 + 3 = 22.

Then the probability of getting red marbles is,

=> P(A) = 6/22.

It can be simplified as,

=> P(A) = 3/11

=> P(A) = 0.27
