Prove that(1 + cb)(x + a) = (a + x)(bc + 1)
You can use:

A+ (associative property of addition)

Ax (associative property of multiplication)

C+ (commutative property of addition)

Cx (commutative property of multiplication)

(1 + cb)(x + a) = (1 + cb)(a + x)

(1 + cb)(x + a) = (1 + bc)(a + x)

(1 + cb)(x + a) = (bc + 1)(a + x)

(1 + cb)(x + a) = (a + x)(bc + 1)

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
