First substitute x for 0.3 and multiply by 5, and you get 1.5 Now we want to isolate the 2y so we subtract 1.5 on both sides. So we have a new equation of 2y=18.5 Now to isolate the y we divide 2 by both sides and you get y=9.25

Answer:

y=9.25

Step-by-step explanation:

5x+2y=20

5(.3)+2y=20

1.5+2y=20

2y=20-1.5

2y=18.5

y=18.5/2

y=9.25

Is the binomial a factor of the polynomial function f(x)=x^3+2x^2-16x-32
GREYUIT [131]

Step-by-step explanation:

f ( 4 ) = 64 + 32 - 64 - 32 = 0

Thus x - 4 is a factor

Find other factors by synthetic division.

"""""""|1"""""2""""- 16"""""-32

"""""4|"""""""4""""""24""""""32

"""""""|1"""""6"" """""8""""""0

( x - 4 ) ( x ² + 6x + 8 ) = 0

( x - 4 ) ( x + 4 ) ( x + 2 ) = 0

x = - 2 , x = - 4, x = 4
