The equation is y=5/2x - 15 or if solving for X is -6
Step-by-step explanation:
In terms of y=mx+b, we are to make the Y by itself.
Step 1. -2y = -5x +30
Make y become positive!
Step 2. 2y = 5x - 30
Distribut the 2 over to make it 1y.
Step 3. 1y = 5/2x - 15
The equation is y=5/2x - 15
If you are to find X it would be....
-15 divided by 2.5 gets you x= -6

Answer:

I would have to go with x = 8 and y = 5, meaning the solution is (8, 5).

Step-by-step explanation:

$5x - 2y = 30$

$5(8) - 2(5) = 30$

$40 - 10 = 30$

$30 = 30$

Simplify -(-2а + 13) + (-9а - 2) - (-7а - 3).<br> 12<br> -12<br> 14а - 12<br> 14а - (-12)

ExtremeBDS [4]

Answer:

-12.

Step-by-step explanation:

-(-2а + 13) + (-9а - 2) - (-7а - 3)

= 2a - 13 - 9a - 2 + 7a + 3

= 9a - 9a - 13 + -2 + 3

= -12.

Find the simplified product.

konstantin123 [22]

Answer:

first multiply 2x with 8

$\frac{16x}{ {x}^{2} + 6x}$

you see in down there is x common so take it as common

$\frac{16x}{x(x + 6)}$

now we have x on top as well as in bottom cut them

$\frac{16}{x + 6}$

here is answer
