Chapter 3: Systems of Equations and Inequalities

$\frac{3p+6}{3}=\frac{p}{2}$

Graph each inequality.

$60.\text{2}y-1\le x$

Write each equation in standard form. Identify A, B, and C.

$60. y=7x+4$

Evaluate each expression if $x=-2,y=6,$and $z=5.$

60. $5x+2y-z$

$\frac{3x+4}{2}+1=\frac{5x+8}{8}$

Identify each function as S for step, C for constant, A for absolute value or P for piecewise.

Evaluate each expression if $x=-2,y=6,$and $z=5.$

61. $3x-y+4z$

Write each equation in standard form. Identify A, B, and C.

$x=y$

$\frac{10y-2}{3}+3=\frac{10y+1}{9}$

Identify each function as S for step, C for constant, A for absolute value or P for piecewise.
