Answer:
Job 2
Step-by-step explanation:
Find how much job 1 pays for 1 hour:
(150 - 30) ÷ 8 = 15
Job 1 pays $15 per hour.
Assuming variable x stands for number of hours worked, job 2 pays $17 an hour.
Put job 1 into a similarly formatted equation:
Variable y = total pay
y = 15x + 30
Compare job 1 and 2:
Job 1: 15x + 30
Job 2: 17x + 25
Just by looking at the two expressions, there is no obvious higher paying job so let's try plugging in 8 hours for x:
15(8) + 30 = 150
17(8) + 25 = 161
$161 is more than $150 so job 2 pays more.

Answer: uhhhhhhhhhhhhhhhhhhh whats the question?
Step-by-step explanation:
Let notebooks be x and let pencils be y
4x+9y=8.25 (equation 1)
7x+14y=14.00 (equation 2)
Multiply equation 1 by 7
So that you get 28x+63y=57.75
Multiply equation 2 by 4
So that you get 28x+56y=56.00
28x+63y=57.75 -
28x+56y=56.00
-----------------------
7y=1.75
Divide both sides by 7
1.75/7 is 0.25
So, now we know that one pencil costs 0.25 cents
Sub this y value into equation one
4x+9(0.25)=8.25
4x+2.25=8.25
Move 2.25 to the other side as a negative number
4x= 6
Divide both sides by 4
6/4 is $1.50
So, one pencil is equal to 0.25 cents and one notebook is equal to $1.50
Answer:
<h3>(3y2+5y-7)+2(y3-4y2+5)</h3>
3y2+5y-7+2y3-8y2+10
3y2-8y2+5y-7+10
-5y2+5y+17
