Step-by-step explanation:
For 1 hour while working he earns $11
For x hours while working he earns $11x
As y is the total money earned,
y=11x
Option C
Answer:
C. y=11x
y = total amount of money earned
x = hours he works
y = 11x
He earns $11 per hour, so multiplying 11 by x, the number of hours, you are able to find the total amount of money he earns, y.
Answer: 3y+7x=4.
Step-by-step explanation: took the test
5=k×
k=180
3=180×
x=60
B
x = -9, -3
x^2 + 12x + 27 = 0
We need 2 numbers whose product is + 27 and whose sum is + 12. These are 3 and 9. So the factors are:-
(x + 3)(x + 9) and this = 0
So (x + 3) = 0 or x + 9 = 0
x = -3 , -9
-32/15/-4/5
-32/15*5/-4
-32*5/15*-4
-160/-60
8/3
