Part A: Explain why the x-coordinates of the points where the graphs of the equations y = 8x and y = 2x + 2 intersect are the so
OleMash [197]

The point of intersection of two given equations is (0.333, 2.667).

Given that, equation with two variables are y = 8x and y = 2x + 2.

The given equations will intersect at some point where y is the same for both equations.

When you replace y in y = 2x + 2 with y = 8x, we get 8x = 2x + 2.

So, the solution of 8x = 2x+2 will satisfy both equations.

Now, we need to find the solutions to take the integer values of x between -3 and 3.

That is,

x = -3 , then 8(-3) = 2(-3) +2⇒-24 = -6+2

⇒-12 = -4    False.

similarly, for x = -2

8(-2) = 2(-2)+2

⇒-16 = -2   False

For, x = -1

8(-1) = 2(-1)+2

⇒-8= 0   False

For, x = 0

8(0) = 2(0)+2

⇒0= 2   False

For, x = 1

8(1) = 2(1)+2

⇒8= 4   False

For, x = 2

8(2) = 2(2)+2

⇒16 = 6   False

For, x = 3

8(3) = 2(3)+2

⇒24 = 8   False

Therefore, there is no solution to 8x = 2x +2 for the integers values of x between -3 and 3.

The equations can be solved graphically by plotting the two given functions on a coordinate plane and identifying the point of intersection of the two graphs.

The point of intersection is the values of the variables which satisfy both equations at a particular point.

Hence, you can see the graph as shown below, the point of intersection is (0.333, 2.667).

Kayla has a deck that measures 4 feet by 21 feet.
Flura [38]

For the area of the deck to be doubled, he should increase each dimension by 3.

<h3>How to find the dimension increase to double the area?</h3>

The deck is 4 feet by 21 feet.

She wants to increase each dimension by equal lengths so that its area is doubled.

Therefore,

initial area = 4 × 21 = 84 ft²

Hence,

The increase by equal length

width = x + 4

length = x + 21

area = 2(84) = 168 ft²

Therefore,

(x + 4)(x + 21) = 168

x² + 21x + 4x + 84 = 168

x² + 25x + 84 = 168

x² + 25x + 84 - 168 = 0

x² + 25x - 84 = 0

(x + 28) • (x - 3)  = 0

x = -28 or 3

It can only be positive.

Therefore, she should increase each dimension by 3.
