Hello from MrBillDoesMath!

Answer:

(1/3) x <= -6 when x >= 18

Discussion:

Solve the inequality:

-(1/3)x < = -6

Add +(1/3)x and + 6 to both sides:

- (1/3)x + (1/3x) + 6 <= -6 + (1/3)x + 6 =>

0 + 6 <= (1/3)x => (multiply both sides by 3)

6*3 <= 3 (1/3) x =>

18 <= x

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

Alinara [238K]

↣ 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.

↣ <em>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. ↣</em>

Answer:

$\frac{x}{3} = \frac{7x}{12x - 15} \\ 12 {x}^{2} - 15x = 21x \\ 12 {x}^{2} -36x = 0 \\ 12x(x - 3) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = 3} \\ \\ \frac{25 - 3x}{x + 5} = 1 \\ 25 - 3x = x + 5 \\ 3x + x = 25 - 5 \\ 4x = 20 \\ \boxed{ x = 5} \\ \\ \frac{3x - 2}{x} = - \frac{8}{x} \\ 3 {x}^{2} - 2x = - 8x \\ 3 {x}^{2} -6x = 0 \\ 3x(x - 2) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = 2} \\ \\ \frac{3 - x}{x} = \frac{x + 1}{2x} \\ 6x - 2 {x}^{2} = {x}^{2} + x \\ 3 {x}^{2} - 5x = 0 \\ x(3x - 5) = 0 \\ \boxed{x = 0} \: or \: \boxed{x = \frac{5}{3} }$
