Which pair shows equivalent expressions?
Plz help me well mark brainliest! T-T

Option 3

Step-by-step explanation:

The first and second option can be eliminated immediately because the first equation simplified is:

2x + 10 = -2(x - 5)

2x + 10 = -2x + 10

The second equation expanded is:

-2(x + 5) = 2x - 10

-2x - 10 = 2x - 10

The third equation expanded is:

-2x - 10 = -2(x + 5)

-2x - 10 = -2x - 10

Meaning this equation is correct.

The fourth equation expanded is:

-2(x - 5) = -2x - 10

-2x + 10 = -2x - 10

Option 3 is the only correct option.

Hope this helps!

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
