Above the graph
look at them
7x-y <span><</span>3
x-y<span><</span>4
2x-9y>2
4x+7y>3
dashed boundary line means it does't include htat means taat the symbol is < or >
cross out first 2
one way is to graph the lines as equations and shade accordingly
2x-9y>2
y<2/9x+2/9
shade on bottom
4x+7y>3
y>-7/4x+3/9
shade on top
aswer is 4x+7y>3
Their earnings would be the same after 4 hours
Let the number of hours be x, and the weekly earning be y
So, the given parameters are:
<u>Kimi</u>
- Earnings = $9 per hour
- Weekly allowance = $8
So, the equation for Kimi's weekly earning is:

<u />
<u>Jordan</u>
- Earnings = $7 per hour
- Weekly allowance = $16
So, the equation for Jordan's weekly earning is:

Equate both equations

Collect like terms


Divide both sides by 2

Hence, their earnings would be the same after 4 hours

It is going to be minus, so negative because a positive times by a negative always gives you negative.
i there would be two negative and three positive factors it would be a minus times by a minus which gives you a plus. if the amount of negatives is odd it will be negative, if it is even then it is going to end up being a positive.
hope i could help.:)
Hi there!
To solve this problem, we need to divide the total amount of tables by the amount of students:
40 / 10 = 4
So, we need 4 tables to seat 40 students.
Hope this helps!
