Help please! i need to find the restrictions to this expression

jarptica [38.1K]

Answer:

x = 7, x = $\frac{-1}{5}$

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).

Since we are only looking at the denominator, you can just ignore the numerator:

(x - 7) (5x + 1)

To find the restrictions, you must set them equal to 0:

x - 7 = 0

5x + 1 = 0

Then, solve:

x - 7 = 0 5x + 1 = 0

+ 7 + 7 - 1 - 1

________ ________

x = 7 5x = -1

x = $\frac{-1}{5}$

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.

After a 15% price reduction, a boat sold for $15,200. what was the boats price before the reduction?

lora16 [44]

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

$\frac{15200}{0.85}=x$
