If you plug in “0” for all x-values and solve for f(x) (or “y”), you will get -6;
therefore, the answer is b = -6
Answer:
its the last one.
Step-by-step explanation:
easy way to do inverse functions:
write out equation :
y = 2
+ 2
Switch the x and y:
x = 2
+ 2
Solve for y :
x = 2
+ 2
subtract 2 both sides
x - 2 = 2
Divide both sides by 2
-
= 
reduce fraction and square root both sides
Y = -1/2x + 4
X + 2y = -8
Replace y in the second equation with the first one:
X + 2(-1/2x +4)=-8
Simplify:
X -X +8 = -8
Simplify:
8 = -8
Subtract 8 from both sides:
0 = -16
This is a false statement, so there are no solutions.
Their average is <em>59/144 .</em>
