Question

3x - 2y < 10 ) 5x - 3-15 부 다. N

Answer 1

Part 1

we have the inequality

3x-2y < 10

isolate the variable y

-2y< -3x+10

Multipli by -1 both sides

2y > 3x-10

the solution is the shaded area above the dashed line 2y=3x-10

using a graphing tool

see the attached figure

please wait a minute to draw the solution

`5x-3y\leq-15`

isolate the variable y

`\begin{gathered} 5x-3y\leq-15 \\ -3y\leq-5x-15 \\ \text{Multiply by -1 both sides} \\ 3y\ge5x+15 \end{gathered}`

the solution is the shaded area above the solid line 3y=5x+15

using a graphing tool

Part 7 we have the inequality
