Last step...
8x = 80 ---divide both sides by 8 ---division property
x = 80/8
x = 10
Be carefully, normally there is no a in your expression. I think you made a mistake.
Hope this helps !

<u><em>Answer:</em></u>45 ft</span>²<span> will be blue
<u><em>Explanation:</em></u><u>1- getting the area of the wall:</u>
area of the rectangle can be calculated as follows:
area = length * width
we are given that:
length = </span>
ft<span>
width = </span>
<span> ft
Now, substituting in the above rule, we can get the area as follows:
area = </span>
*
= 135 ft²<span>
<u>2- getting the area that would be pained blue:</u>
We are given that </span>
<span> of the area of the room would be painted blue, this means that:
area of blue = </span>
<span> * area of room
area of blue = </span>
<span> * 135
area of room = 45 ft</span>²<span>
Hope this helps :)</span>
Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.
I hope this helps!
Answer:
coordinates of the Midpoint = (7 ,4).
Step-by-step explanation:
Given : endpoints are H(10, 1) and K(4, 7).
To find :Find the coordinates of the midpoint .
Solution : We have given that endpoints are H(10, 1) and K(4, 7).
By the mid point segment formula :
.
Here,
Md point =.
Mid point = .
( 7 ,4)
coordinates of the Midpoint = (7 ,4).
Therefore, coordinates of the Midpoint = (7 ,4).
