Simplify. Can you explain it also?

Doss [256]

Answer:

The answer is

<h2> $\frac{3c}{4e}$ </h2>

Step-by-step explanation:

<h3> $\frac{9 {c}^{3}d {e}^{2} }{12 {c}^{2} d {e}^{3} }$ </h3>

To solve the fraction reduce the fraction with d

That's we have

<h2> $\frac{9 {c}^{3} {e}^{2} }{12 {c}^{2} {e}^{3} }$ </h2>

Next simplify the expression using the rules of indices to simplify the letters in the fraction

<u>For c </u>

Since they are dividing we subtract the exponents

We have

<h2> ${c}^{3} \div {c}^{2} = {c}^{3 - 2} = c^{1} = c$ </h2>

<u>For </u><u>e</u>

<h2> $e^{2} \div {e}^{3} = e^{2 - 3} = {e}^{ - 1} = \frac{1}{e}$ </h2>

Substituting them into the expression we have

<h2> $\frac{9c}{12e}$ </h2>

Reduce the fraction by 3

We have the final answer as

<h2> $\frac{3c}{4e}$ </h2>

Hope this helps you

What is the slope of the line that passes through the points (-9, -8)((−15,−16)? Write your answer in simplest form.

alexandr402 [8]

Answer:

Therefore the slope of the line that passes through the points (-9, -8),(−15,−16) is

$Slope=\dfrac{4}{3}$

Step-by-step explanation:

Given:

Let,

point A( x₁ , y₁) ≡ ( -9 ,-8)

point B( x₂ , y₂ )≡ (-15 ,-16)

To Find:

Slope = ?

Solution:

Slope of Line Segment AB is given as

$Slope(AB)=\dfrac{y_{2}-y_{1} }{x_{2}-x_{1} }$

Substituting the values we get

$Slope(AB)=\dfrac{-16-(-8)}{-15-(-9)}\\\\Slope(AB)=\dfrac{-16+8}{-15+9}\\\\Slope(AB)=\dfrac{-8}{-6}=\dfrac{4}{3}$

Therefore the slope of the line that passes through the points (-9, -8),(−15,−16) is

$Slope(AB)=\dfrac{4}{3}$
