What is the solution to the system of equations? (You can either do the substitution or elimination method) x - 2y = 19 x + 3y =
masha68 [24]

Answer:

D. (17,-1)

Step-by-step explanation:

We'll start by canceling out x. To do so, multiple the first equation by -1

-1( x - 2y)=( 19 )(-1)

This gives us:

-x +2y = -19

x + 3y = 14

Add the equations together:

→ 5y = -15

→ y = -1

Plug in y = -1 into an equation:

→ x + 3(-1) = 14

→ x - 3 = 14

→ x = 17

(17,-1)

Hope this helps!

Hello, can you please review attached and help me with the answer ?
Elis [28]

Answer:

<em>(a). P(x) = 8x - 112,000 </em>

<em> (b). $80,000 </em>

Step-by-step explanation:

(a). P(x) = R(x) - C(x)

P(x) = 50x - 112,000 - 42x

<em>P(x) = 8x - 112,000</em>

(b). P(24,000) = 8(24,000) - 112,000  = <em>80,000</em>

----------------------------------------

(a). <em>P(x) = 8x - 112,000</em>

First add 3 to each side

Then divide each side by 5

Step-by-step explanation:

5x - 3 = 12

First add 3 to each side

5x-3+3 = 12+3

5x = 15

Please help!! Due soon!! It's multiple choice!! Can you PLEASE try to show the work? I will give you brainliest!! Please answer
liberstina [14]
16)

(4x + 2) is equal to 150 because they are vertical angles. When two lines intersect, on the opposite sides of the x like these are will be equal to one another. So let’s make them equal to each other.

4x + 2 = 150

Subtract 2

4x = 148

Divide by 4

x = 37

So it will be A

17)

The two angles added up with each other

34 + 146 = 180

Since these two add up to 180 degrees, they would be supplementary angles.

So, H

18)

The two angles will make a 90 degree angle (as shown with the little box formed in the corner)

When angles add up to make 90 degrees, they will be complimentary angles.

So, C.
