E. X=18 you can also just use Photomath or something if you need more help :)

3(x - 4) = 3x - 12 (expand the brackets)
3x - 12 = 2x + 6
3x = 2x + 6 + 12 (put all of the integers on one side)
3x = 2x + 18 (simplify - collect like terms)
3x - 2x = 18 (put all of the unknowns on one side)
x = 18 (simplify - collect like terms)

Therefore, we know that x is equal to 18, and so the answer is E.

Jessie works at least 36 hours a week. She works as a math

Olegator [25]

Answer:

The feasible region is unbounded which is the shaded portion in the graph.

Step-by-step explanation:

Given that, the number of hours Jessie works as a teacher and tutor is y and x respectively, which can't be negative.

So, $x\ge0\;\cdots(i)$

y\ge0\;\cdots(ii)

She works at least 36 hours a week.

$\Rightarrow x+y\ge 36$

$\Rightarrow y\ge 36-x\;\cdots (iii)$

She works as a teacher for al least twice the number of hours she works as a tutor.

$\Rightarrow y\ge2x\;\cdots(iv)$

The boundary of the inequalities from equations (i), (ii), (iii), and (iv) are

$x=0, y=0, y=36-x$ and $y=2x$ .

The feasible region is the shaded portion which is the unbounded region as shown in the graph. Any point P(x,y) from the feasible region will satisfies all the constraints.
