Suppose you work at a job where your pay varies directly as the number of hours you work. your pay for 7.5 hours is $45. find your pay for working 30 hours.

$180.

Step-by-step explanation:

Given: Pay for 7.5 hours is $45.

To find: Pay for working 30 hours.

Solution: It is given that pay for 7.5 hours is $45. In order to find the pay for  hours we first need to find the pay for 1 hour, then we are able to find the pay for 30 hours as well.

Now, pay for 7.5 hours

pay for 1 hour

So, for 1 hour the pay is $6.

Now, to find the pay for 30 hours, we need to multiply the pay per hour by 30.

Therefore, pay for 30 hours

Hence, pay for working 30 hours is $180.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
