Answer:
x = 2
y = -1
Step-by-step explanation:
Since it gives you the value of y already, just plug that into the equation, like so:
y = 4x - 9
x - 3 = 4x - 9
<em><u>Subtract the x from both sides:</u></em>
x - 3 = 4x - 9
-x - x
__________
-3 = 3x - 9
<em><u>Then, add 9 to both sides:</u></em>
-3 = 3x - 9
+9 + 9
________
6 = 3x
<em><u>Divide both sides by 3:</u></em>
2 = x
<em><u>Now plug in x for y:</u></em>
y = x - 3
y = 2 - 3
y = -1

17-8 and 16-7 then use those to find the separate perimeters and add them up
Answer:
The correct answer is A) (f+g)(x) = 15x - 2
Step-by-step explanation:
In order to complete a composite addition function, you need to add the two functions together combining like terms.
(f+g)(x) = f(x) + g(x)
(f+g)(x) = 3x - 10 + 12x + 8
(f+g)(x) = 15x - 2
