Answer 1

(10,5/2) answer is A

Step-by-step explanation:

just took test.

Answer 2

The question is incomplete.

This is the complete question as I found in internet:

Use substitution to determine which of the following points is a solution to the standard form equation below 5x-2y = 10

these are the points:

-1,5

1,5

0,-5

0,5

Answer: (0, -5)

Step-by-step explanation:


point x y 5x - 2y = 10 ?


-1,5 -1 5 5(-1) - 2(5) = - 5 - 10 = - 15 ≠ 10 ⇒ not a solution

1,5 1 5 5(1) - 2(5) = 5 - 10 = 5 ≠ 10 ⇒ not a solution

0,-5 0 -5 0 -2(-5) = 10 ⇒ a solution

0,5 0 5 0 - 2(5) = - 10 ≠ 10 ⇒ not a solution
