Answer:

x=2 or x= 4/5

Step-by-step explanation:

Negative case: -(5x-7) = 3

Multiply

-5x+7 = 3

Rearrange and Add up

-5x = -4

Divide both sides by 5

-x = -(4/5)

Multiply both sides by (-1)

x = (4/5)

Then find the positive case: (5x-7) = 3

Rearrange and Add up

5x = 10

Divide both sides by 5

x = 2

Find the equation of the line perpendicular to y=-4x+3 that also intersects the point (8,1)

Fudgin [204]

Answer:

-1

Step-by-step explanation:

They already did the opposite reciprocal for you.

They have it in the form $y=\frac{1}{4}x+b$ now.

To find b you just enter (x,y)=(8,1).

Let's do that.

$1=\frac{1}{4}(8)+b$

$1=2+b$

Subtract 2 on both sides:

$-1=b$

b=-1
