Answer:
(3,7)
Step-by-step explanation:
A function is a relation in which the members of the domain (x-values) DO NOT repeat. So, for every x-value there is only one y-value that corresponds to it. y-values can be repeated.
Hope this helps!!
Y = 7x + 4
-4 from both sides
y - 4 = 7x
/ 7 on both sides
(y-4)/7 = x
Answer:
x = (y-4)/7
Here, both sides are equal, represented by - sign.
So, 4x + 12 = 60
4x = 60 - 12
x = 48/4
x = 12
In short, Your Answer would be 12
Hope this helps!
Let h = amount of hours

Since they earn $7.50 per hour, we can multiply that by an unknown amount of hours to get $116.25. Let's solve:

Divide both sides by 7.5 to isolate the h, amount of hours.

Simplify.

In conclusion, someone would have to work 15.5 hours to earn $116.25 if they earn $7.50 per hour.
