<h2>
Explanation:</h2>
Let's use a trial and improvement method to find this solution.
Step 1. Let's choose x = 8.5
Substituting into the equation:

Step 2. Let's choose x = 8.4
Substituting into the equation:

Step 3. Let's choose x = 8.3
Substituting into the equation:

Since the sign of the equation changes from positive to negative when evaluating from 8.4 to 8.3, then x = 8.3 seems to be a reasonable value. Finally, the solution to 1 decimal place is:
Answer:
-1
Step-by-step explanation:
slope=(y2-y1)/(x2-x1)=(2-4)/(0+2)=-2/2=-1
Answer:
She would make $327.60 each week after the raise
Step-by-step explanation:
First we need to find how much she will make per hour. We can do this by multiplying the per hour rate by the percentage of the raise.
$7.65 * 7% = $0.54
Now we add this amount to the previous hourly rate.
$7.65 + $0.54 = $8.19
Now that we have the new hourly rate, we multiply it by the number of hours that she works.
$8.19 * 40 = $327.60
