Which equation describes a line passing through (-3,1) that is parallel to y=4x+1?A) y= -0.25x + 0.25

B) y= 4x - 11

C) y= -0.25x + 1.75

D) y= 4x + 13

Answers

Answer:

D. y= 4x + 13

Step-by-step explanation:

the slope would have to be 4 to be parallel

so plug the points in

1=4(-3) + b

1= -12 +b

13 = b

What is the factored form of 125x6 – 8?(5x2 – 2)(25x4 – 10x2 – 4)
(5x2 – 2)(25x4 – 10x2 + 4)
(5x2 – 2)(25x4 + 10x2 + 4)
(5x2 – 2)(25x4 + 10x2 – 4)

Answers

If you would like to know the factored form of 125x^6 - 8, you can find this using the following steps:

125x^6 - 8 = (5x^2 - 2) * (25x^4 + 10x^2 + 4)

The correct result would be (5x^2 - 2) * (25x^4 + 10x^2 + 4).

Solve each equation for the given variable -2x+5y=12 for y
'

Answers

so basically get 1 of y on one side so
-2x+5y=12
add 2x to both sides
5y=12+2x
divide both sides by 5
y=(12+2x)/5
