Tyler needs at least $205 for a new video game system. He as already saved $30. He earns $7 an hour at his job. Write and solve an inequality to find how many hours he will need to work to buy he system. Interpret the solution.

Step-by-step explanation:

Let x represent the number of hours that Tyler works at his job.

He has already saved $30. He earns $7 an hour at his job. It means that if he works for x hours, the total amount that he would save is expressed as

7x + 30

Tyler needs at least $205 for a new video game system. Therefore, an inequality to find how many hours he will need to work to buy the system is

7x + 30 ≥ 205

7x ≥ 205 - 30

7x ≥ 175

x ≥ 175/7

x ≥ 25

He needs to work for at least, 25 hours to get enough money to buy the system.

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
