Use long division if you have to.
The answer is 60
Substitute the 1st equation in the 2nd, we get:
3x + 2(-3 + 2x) = 2
3x -6 +4x = 2
7x = 8
x = 8/7
Replace x = 8/7 in equation 1,
y = -3 + 2(8/7) = -3 +16/7 = -5/7
Answer:
I think it's C
Step-by-step explanation:
A is go up one time
B is go down one time
C is... not sure what's going on there
And D is multiply by 8
I'm confused.
The answer is A. If you substitute -2 and -8/3 for x, the answer is 0.
Replace the x in the equation with the given value of x and you will find that the 3rd equation is corret.
F(X) = 4(1/2)^X
4(1/2)^-2 = 4 * 4 = 16
