D would be the right answer
Simplifying
h(t) = -1t2 + -2t + 30
Multiply h * t
ht = -1t2 + -2t + 30
Reorder the terms:
ht = 30 + -2t + -1t2
Solving
ht = 30 + -2t + -1t2
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by 't'.
h = 30t-1 + -2 + -1t
Simplifying
h = 30t-1 + -2 + -1t
Reorder the terms:
h = -2 + 30t-1 + -1t
Answer:
c=4
Step-by-step explanation:
-5c - 15 = -35
Add 15 to each side
-5c - 15+15 = -35+15
-5c = -20
Divide each side by -5
-5c/-5 = -20/-5
c = 4
