Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20 hours per week. Mike must earn at least $90 to pay his bills.

Step-by-step explanation:

I think the below is your full question:

Mike makes seven dollars an hour working at the grocery store and $10 an hour delivering newspapers. He cannot work more than 20 hours per week. Graph two inequalities that Kishi can use to determine how many hours he needs to work at each job if she wants to earn at least $90 per week.

Here is my

Let x is the number of hours he works at the grocery store

Let y is the number of hours he works at the newspapers

We have two inequalities:

1/ x + y <=> y 20 - x

2/ 7x + 10y <=> y 3/4x + 12.5

Please look at the attached photo

The red line is y 20 - x

The blue line is:  y 3/4x + 12.5  

b

step-by-step explanation:

if a was wrong then it has to be b it cant be c either because not all the y intercepts are the same!

ok now , i would like brainlest plz

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
