The coefficients of the linear equation are:

  • Rate of change = 4.2
  • Initial value = 3.8

This means that the correct options are B and E.

<h3><u>How we can find the linear equation?</u></h3>

First, a general linear equation is written as:

y = a*x + b

Where a is the rate of change (also called slope) and b is the y-intercept (also called initial value).

If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), then the rate of change is given by:

a = \frac{y_2 - y_1}{x_2 - x_1}

In this case, we know that the line passes through:

(1, 8) and (1.5 , 10.1)

Then the rate of change is:

a = \frac{10.1 - 8}{1.5 - 1}  = 4.2

So the line is something of the form:

y = 4.2*x + b

To find the value of b we can use one of the given points, I will use (1, 8).

This means that when x =1, we have y = 8, replacing that we get:

8 = 4.2*1 + b

8 - 4.2 = b

3.8 = b

So we have:

  • Rate of change = 4.2
  • Initial value = 3.8

Then the correct options are:

B and E.

The area of a rectangular wall of a barn is 300 square feet. its length is 10 feet longer than twice its width. find the length
Savatey [412]

<span><span>L * W = 300 sq ft
</span><span> Length is 10 ft greater than twice the width.
L = 2W + 10
Substituting
(2W+10)*W = 300
2W^2 + 10W = 300
Divide both sides by 2
W^2 + 5W = 150
W^2 + 5W - 150 = 0
Factor
(W +15)(W -10) = 0</span></span>

<span>
<span> Roots are W=-15 and W=10.
A negative width is impossible, so W=10
L = 2W + 10
L = 2(10) + 10
L = 30</span></span>

 length = 30 feet, width = 10 feet

<span> Check: 30*10 = 300</span>
