Line AB passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to

amid [387]

parallel means "same slope (m)"

m = $\frac{y2 - y1}{x2 - x1}$ = $\frac{0 - 5}{-3 - (-6)} = \frac{-5}{-3 + 6} = \frac{-5}{3}$

Now, input the point (0, 0) and the slope $(\frac{-5}{3})$ into the Point-Slope formula:

y - y₁ = m(x - x₁)

y - 0 = $\frac{-5}{3}$ (x - 0)

y = $\frac{-5}{3}x$

3y = -5x <em>multiplied both sides by 3</em>

0 = -5x - 3y <em>subtracted 3y from both sides</em>

Put the following steps in order for multi step equations

Soil is the thin layer of material covering the earth's surface and is formed from the weathering of rocks. It is made up mainly of mineral particles, organic materials, air, water and living organisms—all of which interact slowly yet constantly. ... Therefore, most living things on land depend on soil for their existence.

ITS URGENT PLEASE HELP!!! I will give brainliest if correct! Someone please help?

QveST [7]

Answer:

D, E, C, A, and B.

Step-by-step explanation:

We wish to solve the equation:

$2(x-3)+7-3x=11$

Let’s go through this step-by-step.

1) Distributive Property:

$2x-6+7-3x=11$

2) Commutative Property of Addition (we rearrange them):

$2x-3x-6+7=11$

3) Combined Like Terms:

$-x+1=11$

4) Addition Property of Equality* (we add <em>-1</em> to both sides):

$-x=10$

5) Multiplication Property of Equality (we multiply both sides by -1):

$x=-10$

So, our sequence is:

D, E, C, A, and B.

*A better choice would’ve been the Subtraction Property of Equality, but both are equally fine.

What are the solutions to the equation?

olga2289 [7]

Answer:

x = −10 and x = 4

Step-by-step explanation:

x2 + 6x = 40

Subtract 40 from each side

x^2 + 6x -40 =0

Factor, what 2 numbers multiply to -40 and add to 6

10 * -4 = -40 10+-4 = 6

(x+10) (x-4) = 0

Using the zero product property

x+10 =0 x-4=0

x=-10 x=4
