Answer:
how do you want me to help you with
Step-by-step explanation:
Answer:
(1,-1)
(7,12)
(5,-3)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
we have

Verify each case
case 1) we have
(1,-1)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
case 2) we have
(7,12)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
case 3) we have
(-6,-3)
substitute the value of x and the value of y in the inequality and then compare the results

----> is not true
therefore
The ordered pair is not a solution of the inequality
case 4) we have
(0,-2)
substitute the value of x and the value of y in the inequality and then compare the results

----> is not true
therefore
The ordered pair is not a solution of the inequality
case 5) we have
(5,-3)
substitute the value of x and the value of y in the inequality and then compare the results

----> is true
therefore
The ordered pair is a solution of the inequality
Answer: He earns $169 after 13 hours
Step-by-step explanation:
To solve this we need to find out how much he earns per hour.
This can be identified using simply division.
130/10=13
He earns $13 per hour.
Now we multiply 13*13=169
He earns $169 after 13 hours
