Answer:
an needs to walk dogs for at least 9 hours in order to earn more than $520 a week.
Step-by-step explanation:
Since his car wash attendant job pays $400 a week then you can subtract that from your final revenue.
$520-$400=$120
Now, to find out how many hours he has to walk dogs for in order to earn more than $520, you need to know some basic multiplication so...
$15×8=$120
...but he needs to earn MORE than $520 so...
$15×9=$135
$400+$135=$535.
3(1) - 8 = 3 - 8 = -5
just plug in 1 for x that's what f(1) means
Answer:
-infinity, infinity
Step-by-step explanation:
Domain is x, and in a quadratic equation like this one the x axis goes on forever. So the first answer of -infinity, infinity is correct.
Start by taking away 22.36 from each side so that you are left with 4.73c = 42.57
And then divide each side by 4.73 so you will get c = 9
