Are you trying to make this into a function?
f(x)=6x
Good luck!
Answer is (x-1)and (x-2).First make the equation 3x^2- 9x+6=0. then divide both sides by 3 and then the two factors are (x-1)(x-2)
Answer:
A = 100 B = 130 C = 150
Step-by-step explanation:
Translated into a system of equations:
A+B+C = 380
B = A+30
C = B + 20
So we find B from the last one:
B = C-20
Plug it in the second one:
C-20 = A+30
A = C-50
Plug it in the first:
C-50 + C-20 + C = 380
3C - 70 = 380
3C = 450
C=150
A = C - 50 = 150 - 50 = 100
B = C - 20 = 150 - 20 = 130
#7:
It means to solve for y.
#8:
We can write:
l = w + 2
Because it says the length is 2 more than the width.
Answer:
8
Step-by-step explanation:
volume of cube = side lenght ^3
= 2^3
= 8cubic inch.
