Answer:
x= -8
Step-by-step explanation:
This can be done several ways:
The easiest is to factor out 12 from both sides so:
12(9-6x) = 12 (58-1)
12(9-6x) = 12 (57)
Cancel 12 from both sides so:
9-6x = 57, then...
-6x = 48
x= -8
You just have to plug in each value of x into the equation of 3x^2. Since y is a function, it is also written as f(x)
Answer:
y = 40, x = 9
Step-by-step explanation:
2(3y)+2(2y-20)=360
y = 40
2x=18
x = 9
