Acashier earns $7 an hour. if x is the number of hours worked, which function represents the cashier’s earnings? y = 7x y = x 7 y = 7/x y=7

y= 7x

Step-by-step explanation:

A cashier earns $7 an hour. If x is the number of hours worked,

y be the cashier's earning

To find cashier's earning we multiply the amount earns in 1 hour by the total number of hours worked

Total earnings depends on the total number of hours worked

Total earnings = earning per hour * number of hours worked

Cashier's earnings = 7 * x= 7x

y= 7x

the answer to the expression is 83

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
