Answer:
2y
Step-by-step explanation:
The correct answer would be C) 3%
<span>The function h(t) = 210 – 15t has the slope-intercept form of the equation of a straight line. The y-intercept represents the amount h at the very beginning (when t=0). The negative slope (-15) represents the amount by which h will decrease if t is increased by 1.
We are manipulating the value of time, t, so time, t, is the independent variable, and h(t) = y is the dependent variable.</span>
The answer is C! All you have to do is subtract the numbers! :) (Also, could I get brainliest?)
