First, we can simplify it down. 
x = (-x + 6)^2
Then, you should have x - (x^{2} - 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.

Which sequence is modeled by the graph below? coordinate plane showing the points 1, 2; 2, 2; 3, 2; 4, 2
prisoha [69]

We will start with plotting the x coordinates and y coordinates on the graph

The points 1, 2; 2, 2; 3, 2; 4, 2  have been plotted on the graph which has been attached as an image to the solution.

We can see that the value of y is staying constant (2) for all values of x.

Hence, the points represent the equation y = 2.

stich3 [128]

Answer:

D: y= -5x+12

Step-by-step explanation:

Since the slope is -5 is either C or D. Let's replace x= 2 in either to see what we get.

C: -5(2)-2 = -12 Nope.

D: -5(2) +12 = 2 Good!

The function y=−0.25x+0.55 represents the percent y (in decimal form) of battery power remaining x hours after you turn on a lap
AURORKA [14]
Answer: a is 2.2, b is 0.55
Explanation:
To find the x intercept, put 0 instead of y,
hence,
0=-0.25x+0.55
-0.25x=-0.55
x=2.2
To find y intercept put 0 instead of x,
so,
y=-0.25*0+0.55
y=0+0.55
y=0.55

Answer:

t=5 dollars per t-shirt

Step-by-step explanation:

<em>Read the problem and write your equation while following along with it</em>

We have 8 t-shirts

Lets 8 t-shirts be represented by 8t

So for our equation we will place and 8

<h3>Our equation: 8t</h3><h3 />

Now it says we have a coupon that subtracts 4 dollars from our total

<h3>Our equation: 8t-4</h3><h3 />

The final part to add to our equation says that our total before tax was 36 dollars

<h3>So here is our equation: 8t-4=36</h3><h3 />

<em>add </em>$4<em> to both sides</em>

8t=40

<em>Divide both sides by</em> 8

t=5 dollars per t-shirt

-Side note, make sure to spell your question right. It was a tad bit confusing to read at the start.

-Brainliest please :)
