Answer:

Hello There. ☆~\---___`:•€`___---/~☆ The correct answer is C. Both (1,3) and (-2,-4).

To check whether (-2,-4) is a solution of the equation let's substitute x= -2 and y= -4 into the equation:

-7x+3y=2

-7*(-2)+3*(-4)=2

14-12=2

2=2

Do the same thing with (1,3)

-7x + 3y = 2

-7 * 1 + 3 * 3 = 2

-7 + 9 = 2

2 = 2.

Hope It Helps!~ ♡

6. Solve the equation.<br> 2x - 3 = -4x - 9<br> A-1<br> B 6<br> C-6<br> DO
Oksanka [162]

Answer:

x=-1

Step-by-step explanation:

2x - 3 = -4x - 9

Add 3 and 4x on both sides.

2x + 4x = -9+3

Add or subtract like terms.

6x = -6

Divide 6 into both sides.

6x/6=-6/6

x=-1

The solution to this equation is x=-1.

levacccp [35]
Let's review all the answers that it could be.
A. The hundredths place is 10 times smaller than the tenths place, so the answer cannot be A.

B. This one makes sense, 10 is 10 times greater than 1 so the answer should be B, but let's just check the others to be sure.

C. This is the same as answer A. Hundredths is actually smaller than tenths, so the answer cannot be C.

D. This one does not give adequate information.

I believe the answer is B.<span>The 4 in the tens place is 10 times the value of the 4 in the ones place.
