Angle 12 is 115
Answer:
x = 7, x = 
Step-by-step explanation:
A restriction can only be found in the denominators and this is when x is a certain number that when plugged in, makes the expression 0 (this makes it undefined, which you cannot have).
<em><u>Since we are only looking at the denominator, you can just ignore the numerator:</u></em>
(x - 7) (5x + 1)
<em><u>To find the restrictions, you must set them equal to 0:</u></em>
x - 7 = 0
5x + 1 = 0
<em><u>Then, solve:</u></em>
x - 7 = 0 5x + 1 = 0
+ 7 + 7 - 1 - 1
________ ________
x = 7 5x = -1
x = 
If you plug these numbers in, the total outcome would come out to be 0, making the expression undefined, proving that these are the restrictions of the expression.
Given that after a 15% price reduction, a boat sold for $15,200. Now we have to find the boats price before the reduction.
Let the boats price before the reduction = x
Reduction = 15% of original price = 15% of x = 0.15x
Then selling price will be difference of original price and reduction
Selling price = Origina price - Reduction
15200 = x - 0.15x
15200 = 0.85x

17882.3529412=x
Hence origina price before reduction is approx $17882.35
Answer:

Step-by-step explanation:
we know that
The rule of the translation is equal to

That means
The translations is
units to the right and
unit up
