What is the equation of a line that is perpendicular to y=0.25x-7 and passes through the point -6,8
Olenka [21]

Answer:

The equation ls: y = -4x - 16

Step-by-step explanation:

Given the point (-6, 8)

Given the line y = .25x - 7

Use a fraction:

y = 1/4x - 7

The slope is 1/4 (or .25)

The slope of a perpendicular line is the negative inverse or -4.

Use the point slope form and substitute:

y - y1 = m(x - x1)

y - 8 = -4(x - (-6))

y - 8 = -4x - 24

y = -4x - 16

Proof:

f(-6) = -4(-6) - 16

= 24 - 16

= 8, giving (-6, 8)

What is 96-4.5y-3.2y=5.6y+42.80<br><br> PLEASE HELP!!!!
Lady_Fox [76]
You want to combine like terms. so -4.5y-3.2y=-7.7. so no it’ll look like 96-7.7y=5.6y+42.80.
no you’ll bring 96 to the other side so now it’s
-7.7y=5.6y-53.20
now you’ll bring 5.6y to the other side. -13.30y=-53.20. you want the variable by itself so do -13.30 divided by both sides

please help me. how would you change x + 3y = 18 -3x -12y = -75 to eliminate y showing all of the work
Svetlanka [38]

Answer:

x = -3

y = 7

Step-by-step explanation:

x + 3y = 18

-3x - 12y = -75

multiply first equation by 4

4 × (x + 3y) = 18 ➡ 4x + 12y = 72

now add the two equations up

4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)

x = -3
