Answer:
x = 2/5
Step-by-step explanation:
5x=2
Divide each side by 5
5x/5 = 2/5
x = 2/5
There are 60 minutes in an hour and percent means per one hundred so:
p/100=18/60
p=1800/60
p=30%
Jamie has earned $80 +75 +145 +250 +80 = $630 so far this week. He needs to earn an additional $875 -630 = $245 to pay his bills.
If Jamie only has one last task, he must earn $245 on that task to pay his bills this week.

Answer: Choice C</h3><h3>
{ (-2,2), (0,2), (7,2), (11,2) }</h3>
Here we don't have any repeated x values.
In choice A, x = 2 repeats. In other words, x = 2 leads to multiple y outputs. So this is not a function. Choices B and D are similar stories. A function is only possible if every x leads to exactly one y value only. The graph must pass the vertical line test.
Side note: the y values can repeat, but the function won't be one-to-one.
