Answer:
25 and 54
Step-by-step explanation:
(a)
6z² - 2z + 5 ← substitute z = 2
= 6(2)² - 2(2) + 5
= 6(4) - 4 + 5
= 24 - 4 + 5
= 20 + 5
= 25
(b)
64 - 5z ← substitute z = 2
= 64 - 5(2)
= 64 - 10
= 54
Answer:
4x-15=y
Step-by-step explanation:
The higher the rise over the run the more steep your slope will be thus 4x is less steep than 8x because it does not rise as much.
The y intercept shifted downward means anything (-10>b) can be plausible for b.
