HELP ME PLEASE!! Write the absolute value equations in the form x−b=c (where b is a number and c can be either number or an expression) that have the following solution sets:
A. Two solutions: x=2, x=13.
B. One solution: x=23.
C. Two solutions: x=1/2, x=1/3
D. One solution: x=−3.
E. One solution: x=−4.1.
F. All numbers such that x≥5.
G. All numbers such that x≤5.
H. All numbers such that x≤−14.

In trapezoid efgh, m∠hef=(4x2+16)∘ and m∠gfe=(5x2+12)∘. find the value of x so that efgh is isosceles. i'm desperate.

Phyllis and chen are saving money to go to a football game. each friend starts with some money and saves a specific amount each week. phyllis made a graph to show the total she has saved at the end of each week. chen wrote an equation to show the total, y, he has saved at the end of each week, x. y = 15x + 15 compare the amount that each friend has when both friends start saving. select the correct answer from the drop-down menu to complete the statement. phyllis starts with $ and chen starts with $

Choose the linear inequality that describes the graph. the gray area represents the shaded region. a: y ≤ –4x – 2 b: y > –4x – 2 c: y ≥ –4x – 2 d: y < 4x – 2
