Answer: you have to substitute them into the equation

Step-by-step explanation:

example: x = 2y - 6

lets say you test 4/5 so it would be 4 = 2(5) - 6

this equals 4 = 10 - 6 which is true

so that is how you test to see if the equation is right

remember the first number goes to "x" and the second one goes to y

hope this helps mark me brainliest if you can

Answer:

see explanation

Step-by-step explanation:

Slope- intercept form is y = mx + c

Rearrange the given inequalities into this form

x + y ≤ 55 ( subtract x from both sides )

y ≤ - x + 55

-------------------------------------------------

60x + 40y > 600 ( subtract 60x from both sides )

40y > - 60x + 600 ( divide all terms by 40 )

y > - \frac{3}{2} x + 15

PLEASE HELP ASAP!! No explanation needed. Just yes or no please!

Answer: A) Yes, it is a solution.

=================================================

Explanation:

Replace every x with -3 and simplify both sides.

3x - 2 < 2 - 2x

3(-3) - 2 < 2 - 2(-3)

-9 - 2 < 2 + 6

-11 < 8

Since -11 is to the left of 8 on the number line, this means the inequality -11 < 8 is true. Consequently, it means the first inequality is true when x = -3.

Therefore, x = -3 is a solution.
