Find the equation of the line perpendicular to y = 3x - 6 that runs through the point (-1, -3).
Mkey [24]

Answer:

Step-by-step explanation:

I'll get you the answer. You pick it from what you are given.

The slope of the perpendicular is m1 * m2 = - 1

m1 = 3

m2 = -1 / m1

m2 = -1 / 3

So far what you have is

y = (-1/3) x + b

Use the point go get b

x = -1

y = - 3

y = (-1/3) *x + b

-3 = (-1/3)*-1 + b

-3 = 1/3 + b  

-3 - 1/3 = b

b = -3.33333  or

b = -3 1/3

b = -10/3              

So the answer is

y = (- 1/3) x - 10/3            or

y = (-1 / 3)x - 3.3333       or

y = (-1/3 )x  - (3 1/3)

Your math teacher asked you to solve the equation in the box.
lawyer [7]

Answer:

x = x - 4/6

false

Step-by-step explanation:

6(x - 1) - 4x = 2(3x - 5)

First, lets distribute the 6 to each item inside the parentheses on the left side. You can do this by multiplying the 6 by each term.

6 * x = 6x

6 * -1 = -6

6x - 6 - 4x = 2(3x - 5)

Next, we will combine like terms.

6x - 4x = 2x

2x - 6 = 2(3x - 5)

Now, let's look at the right side of the equation.

Let's distribute the 2 to each item inside the parentheses on the left side. You can do this by multiplying the 2 by each term.

2 * 3x = 6x

2 * -5 = -10

6x - 1 = 6x - 5

Immediately, we can tell this is false, but let's solve the equation just to make sure.

6x - 1 = 6x - 5

+1              +1

6x = 6x - 4

---     --------

6        6

x = x - 4/6

This is false.
