Answer:

(-4,3)

B is the correct option.

Step-by-step explanation:

We have been given the expression 2(1,0) -3(2,-1)

On distributing 2 and -3 over the parentheses, we get

(2×1,2×0)+(-3×2,-3×(-1))

On simplifying, we get

(2,0)+(-6,3)

Now, adding, we get

(2-6,0+3)

On simplifying, we get

(-4,3)

B is the correct option.

HELP I give big brain! See attachment
Makovka662 [10]

Answer:

35

Step-by-step explanation:

Here is the full steps:

Distribute

-7(x+10)=7(5-x)

-7x-70=7(5-x)

Distribute

-7x-70 = 35-7x            → Answer for the attachment "35"

Add 70  to both sides of the equation

-7x-70+70=-7x+35+70

Simplify

-7x=-7x+105

Add 7x  to both sides of the equation

-7x+7x=-7x+105+7x

0 = 105
