Step-by-step explanation:
1. You know that the student earned 42 out of 50 points on the last test.
2. Then, to calculate the percent the student earned, you must divide 42 points by 50 points and then you must multiply by 100, as you can see below:
Let's call the percent the student earned. Then:

Answer:
<h2>
x=-1 and x=2</h2>
Step-by-step explanation:
The "holes" are the x-es where function doesn't exist.
one must not divide by 0, so given function doesn't exis if the denominator is equal 0
The product {(x+1)×(x-2)} is equal 0 if any of factors {(x+1),(x-2)} is 0, so
x + 1 = 0 or x - 2 = 0
x = - 1 or x = 2
-x+8+3x=x-6
Combine like terms:
8 + 2x = x-6
Subtract x from each side:
8 + x = -6
Subtract 8 from each side:
x = -14
