Answer: Your answer is going to be D. (10, -1)
Step-by-step explanation:
Starting off the equation you want to get rid of either x or y ( I did x first)
Take x+3y=7 and multiply the entire equation by -2 -- -2(x+3y=7)
You get -2x-6y=-14 and then add the two equations together
-2x-6y=-14
2x-4y=24 -- You get -10y = 10
y = -1
You can take the -1 and plug it back into either equation.. ( I did x+3y=7)
x+3(-1)=7 -- x-3=7 -- Add the 3 to get the 10 ( x = 10 )
So you have x = 10 & y = -1
(10,-1)

I hope these r the answers.
Answer: (f·f)(0) = 4
(fof)(0) = -8
<u>Step-by-step explanation:</u>
f(x) = 3x - 2
(f·f)(x) = (3x - 2)(3x - 2)
= 9x² - 12x + 4
(f·f)(0) = 9(0)² - 12(0) + 4
= 4
(fof) = 3(3x - 2) - 2
= 9x - 8
(fof)(0) = 9(0) - 8
= -8
<em>I wasn't sure if you wanted multiplication or composition so I solved both</em>
The answer is 63/5ft long of the actual car. Hope this helps :)
Answer:
x = 8
Step-by-step explanation:
A line with "undefined" slope is a vertical line, whose equation is of the form ...
x = constant
In order for the line to go through a point with an x-coordinate of 8, the constant must be 8.
x = 8 . . . . . a vertical line through (8, -3)
