mihalych1998 [28]3 years ago

5 0

Answer: To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line. If the inequality is strict ( < or > ), graph a dashed line.

Give each answer as mixed number in simplest form

telo118 [61]

Step-by-step explanation:

$= \frac{1}{2} + ( - 5 \frac{9}{10} )$

$= \frac{1}{2} - 5 \frac{9}{10} \\$

$= \frac{1}{2} - \frac{5 \times 10 + 9}{10} \\$

$= \frac{1}{2} - \frac{59}{10} \\$

$= \frac{1}{2} \times \frac{5}{5} - \frac{59}{10} \\$

$= \frac{5}{10} - \frac{59}{10} \\$

$= \frac{5 - 59}{10} \\$

$= - \frac{54}{10} \\$

$= - \frac{27}{5} \\$
