Which expressions are equivalent to the given expression. y^-8y^3x^0x^-2

vesna_86 [32]

$y^{-8} y^3 x^0 x^{-2}$ is equivalent to $y ^{-5} x ^{-2}\\$ .

<h3>What is a simplification of an expression?</h3>

Usually, simplification involves proceeding with the pending operations in the expression.

Simplification usually involves making the expression simple and easy to use later.

Given;

$y^{-8} y^3 x^0 x^{-2}$

Simplify

$y^{-8} y^3 x^0 x^{-2}\\\\y ^{-8+3} x ^{0-2}\\ \\y ^{-5} x ^{-2}\\$

Hence, $y^{-8} y^3 x^0 x^{-2}$ is equivalent to $y ^{-5} x ^{-2}\\$ .

Sam baby-sat for x hours and earned $75. If he baby-sits for y more hours at the same rate, his total earnings will be $100. Whi

77julia77 [94]

The situation can be modeled with the linear equation:

$75 + y*($75/x) = $100

<h3>Which of the following equations represents this situation? </h3>

We know that if she wors for x hours, she earns $75.

This means that the amount that she gets per hour is:

R = $75/x.

Now, if she works y more hours, then she gets another $25 (for a total of $100).

We can write this as a linear equation:

y*($75/x) = $25

We can rewrite this as:

$75 + y*($75/x) = $100

So the correct option is B.
