Answer:
-5
Step-by-step explanation:
f (x) = 4 - x^2
f (-3)= 4 - (-3)^2
= 4 -(9)
= -5
-3x-y = -17
-x+y=-1
Using addition
-4x +0y = -16
-4x=-16
x=4
Then plug the value of x into one of the original equations
-x+y=-7
-(4)+y=-7
y=-7+4
y=-3
The solution is x=4 and y=-3
Thus (4,-3)

Answer:
2nd, 3rd, 5th are True
Step-by-step explanation:
2(9)(7b + 4) = 18(7b + 4) = 126b + 72
7 is the coefficient of the term '7b'
8 and 1 can be combined, therefore they are 'like terms'
2 is a factor is true
