It would be -2z+8. Because 3z+-5 is -2 and 2+6 is 8.
Answer:
75%
Step-by-step explanation:

Answer:
B. f(x)
D. h(x)
Step-by-step explanation:
An exponential function will have a common ratio.
We check and see if the consecutive terms has a common ratio.
For f(x),

This is not an exponential sequence.
For g(x), we have:

For h(x),

This is not an exponential sequence
For k(x),

Answer: the answer is the second option.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
given the 2 equations
x + y = 0 → (1)
5x + 3y = - 8 → (2)
Rearrange (1) expressing x in terms of y by subtracting y from both sides
x = - y → (3)
Substitute x = - y into (2)
5(- y) + 3y = - 8, that is
- 5y + 3y = - 8
- 2y = - 8 ( divide both sides by - 2 )
y = 4
Substitute y = 4 into (3) for corresponding value of x
x = - y = - 4
Solution is (- 4, 4 ) → C
