(x-5)(x+3) = 0
Apparently, the other solution is x = 5.
Answer:
x=3
Step-by-step explanation:
1. Rearrange terms
1 - 6x = -17
-6x + 1 = -17
2. Subtract 1 from both sides of the equation (we want to get rid of 1)
3. Simplify
In the end, you should get x=3.

Answer: Choice D</h3>
=====================================================
Work Shown:
The idea is to swap each x and y, then solve for y to find the inverse.
Answer:
Her weekly expenses is $234
Step-by-step explanation:
At $7.20 per kilogram
From selling 90 kg, she will have
$7.20 × 90
= $648

To get her expenses, we subtract net profit from total income
$648 - $414
= $234
1.Since 5 is less than 8, borrow 1 from the next column to make 15.
2.Calculate 15 - 8, which is 7.
3.Calculate 3 - 3, which is 0.
4.Since 2 is less than 5, borrow 1 from the next column to make 12.
5.Calculate 12 - 5, which is 7.
6..<span>Calculate 9 - 2, which is 7.</span>
7.<span>Therefore, 102.45 - 25.38 = 77.07.</span>
