<h3><u>
Answer:</u></h3>

<h3>
<u>Step-by-step explanation:</u></h3><h3 />
Given that, The midpoint of overline AB is M(-4, -7). If the coordinates of A are (−7,−6). And we need to find the coordinates of B. We know Midpoint formula is :-
Let the co ordinates of B be (x , y ) .
Now , on substituting the respective values ,we have :-

Hence the value of x coordinate is (-1) and y - coordinate is (-8) .
<h3>
<u>Hence </u><u>the </u><u>coord</u><u>inate</u><u> </u><u>of</u><u> </u><u>B</u><u> </u><u>is</u><u> </u><u>(</u><u>-</u><u>1</u><u>,</u><u>-</u><u>8</u><u>)</u><u> </u></h3>

Answer:
f(2) = 0
Step-by-step explanation:
All we have to do is substitute 2 in for x everywhere in the expression defined by f(x)
-3(2)(2) + 6(2)
-12 + 12
0
Answer:
(f•g)(3) = -7
Step-by-step explanation:
f(x)=-2x + 7
g(x) = x^2 – 2
(f•g)(3) = -2(x² - 2) + 7
(f•g)(3) = -2x² + 4 +7
(f•g)(3) = -2x² + 11
(f•g)(3) = -2(3)² + 11
(f•g)(3) = -2(9) + 11
(f•g)(3) = -18 + 11
(f•g)(3) = -7
