CAN SOMEONE PLEASE HELP I NEED THIS IN BY 11:59 PLEASE IM GUVING BRAINLIEST

Error Analysis:

The mistake Elise of multiplying the revealed part (over whole) by the percentage given. She calculated 25% of the math students surveyed rather than finding the students in whole.

Correct Work:

20 students / .25 = 80 students surveyed

Or

20 students * 4 = 80 students surveyed.

step-by-step explanation:

goog be able to you with that maybe

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
