Mr. Mole left his burrow that lies below the ground and started digging his way at a constant rate deeper into the ground. After 5 minutes of descending at a rate of 1.8 meters per minute, he was 13.5 meters below the ground. Let y represent Mr. Mole’s altitude (in meters) relative to the ground after x minutes.

Complete the equation for the relationship between the altitude and number of minutes.

Y=

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

step-by-step explanation:

use that smart brain

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
