A scuba diver dove from the surface of the ocean to an elevation of -89 9/10 feet at a rate of -21.2 feet per minute. After spending 14 minutes at that elevation the driver ascended to an elevation of -38 9/10 feet. The total time of the five so far was 21 1/8 minutes. What was the rate of change in the divers elevation during ascent?

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d

12cm

the answer is d
