Answer:
x = -8
Step-by-step explanation:
Step 1: Write equation
5x - 7(x + 1) = 9
Step 2: Solve for <em>x</em>
- Distribute -7: 5x - 7x - 7 = 9
- Combine like terms: -2x - 7 = 9
- Add 7 to both sides: -2x = 16
- Divide both sides by -2: x = -8
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
5(-8) - 7(-8 + 1) = 9
-40 - 7(-7) = 9
-40 + 49 = 9
9 = 9
A carpenter buys $54.38 worth of parts from a supplier. if he pays for the parts with a $100 dollar bill, he will receive 100 minus 54.38 = 45.62 in change
hope this helps you good luck

194 is your answer.
<span>Since you have a three digit number the hundredth digit is not zero. Then from the fact that h = t -8, t must be 9, then u = 9-5 or 4.</span>

g(x) = x⁶
Bounded (Partitioned) by x-axis
<u>Step 2: Identify Bounds of Integration</u>
<em>Find where the functions intersect (x-values) to determine the bounds of integration.</em>
Simply graph the functions to see where the functions intersect (See Graph Attachment).
Interval: [-1, 1]
Lower bound: -1
Upper Bound: 1
<u>Step 3: Find Area of Region</u>
<em>Integration</em>
