Question

Given the domain {-4, 0, 5}, what is the range for the relation 12x, + 6y = 24?

Answer 1

↣ Substitute all domains in the equation for the ranges.

$12x+6y=24$    

$2x+y=4$     ↣ Divide the whole equation by 6.

↣ Substitute x = -4 in the equation.

$2(-4)+y=4\\-8+y=4\\y=4+8\\y=12$

Our range is 12 when x = -4. In the choice there is only one choice that has range value as 12. Therefore, the answer is B.

↣ If you want me to solve for all ranges then you can reply under this. Since there is only one choice that has 12 as range value, I decide not to continue. So If you want me to solve for all ranges then feel free to reply under this. ↣
