Step-by-step explanation:
Answer:
x = -6
Step-by-step explanation:
-1.5x = 9 Divide the -1.5 on both sides
x = -6
Plug in the answer to make sure it works.
-1.5(6) = 9
9 = 9
3*3^2+2*10^2-15=212
The answer is 212
1.y varies directly with x
2.substitute the value of x and y in the equation below
y=kx
where k is the constant term
60=20k
k=60\20
k=30
:y=30x.....is the law
To find y when x is 12
You reinstate the law which is y=30x
Then substitutes the value of x to determine y
y=30*12
y=36.
