Answer:
900
Step-by-step explanation:
Answer:
h = 12.5
Step-by-step explanation:
Simplifying
h + 3h + 4h = 100
Combine like terms: h + 3h = 4h
4h + 4h = 100
Combine like terms: 4h + 4h = 8h
8h = 100
Solving
8h = 100
Solving for variable 'h'.
Move all terms containing h to the left, all other terms to the right.
Divide each side by '8'.
h = 12.5
Simplifying
h = 12.5
Is positive. In fact, the square of any (real) number other than 0 is always positive.
The slope is 0.5 tablespoon per minute, which you can deduct from the increase of y from one minute to the next.
The initial value (at x=0) is 1. So the equation is:
y = 0.5x + 1. That's the last one in the list, answer D.
