Select all the ordered pairs that are solutions to the equation 5x + 2y = -8

Question options:

(4, -14)

(0, -4)

(-4, 0)

(1, -2)

(−85,0)

The answer to your question is only (0, -4) is a solution to the equation.

Step-by-step explanation:

Equation

                      5x + 2y = - 8

Process

1) Substitute all the possible solutions in the equations to find the answer

a) (4, 14)

                      5(4) + 2(14) = - 8                  

                       20 + 28    = -8

                                  48 = -8                This is not a solution

b)

                      5(0) + 2(-4) = - 8

                         0     - 8    = -8              This is a solution

c)

                      5(-4) + 2(0) = - 8

                      -20   + 0     = -8

                                -20  = -8                 This is not a solution

d)

                      5(1) + 2(-2) = - 8

                           5  +  -4 = 8

                                     1 = 8                   This is not a solution

e)

                      5(-85) + 2(0) = - 8

                           -425 + 0 = -8

                                  -425 = -8              This is not a solution

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
