32,005,008 = 30,000,000 + 2,000,000 + 5,000 + 8
Answer:
C
Step-by-step explanation:
you need to start by plugging in -2x+4 every were it says y then solve for x when you have found x plug it into one of the equations and solve for y
Answer:
63.66
Step-by-step explanation:
Mean=(65.9+80.8+60.8+46.5+64.3)/5
Mean=63.66
a(x+1)(x-1)+b(x-2)(x+1)+(x+1)^2=9x^2-x-10
(x+1)(a(x-1)+b(x-2)+(x+1))=(x+1)(9x-10)
a(x-1)+b(x-2)+x+1=9x-10
Now this equation is much simpler!
(a+b)x-a-2b+x+1=9x-10
(a+b)x-a-2b=8x-11
(a+b-8)x-a-2b-11=0
a+b-8=(a+2b-11)/x
I can't solve it 3 variables and 1 equations means infinite answers so yea.
