Answer:

C) (7 , 14)

Step-by-step explanation:

Substitute each ordered pair into the equation

-5x + 3y = 7.

A) (2 , -1)

-5(2) +3(1) = -10 +3 = -7 this does not equal 7 so not true

B) (-5 , 3)

-5(-5) +3(3) = 25 +9 = 34 this does not equal 7 so not true

C) (7 , 14)

-5(7) + 3(14) = -35 + 42 = 7 this equals 7 so true

D) (-2 ,−135)

-5(-2) + 3(-135) =10+405 =415 this does not equal 7 so not true

What is the solution to the equation 0.8m − 4 = −0.8m?

lidiya [134]

Answer:

m = 2.5

Step-by-step explanation:

Add 0.8 m to both sides, obtaining 0.8m + 0.8m - 4, or 1.6m - 4 = 0.

Now add 4 to both sides. Result: 1.6m = 4, and m = 4/1.6 = 2.5 = m
