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

Factor the quadratic expression in the equation y=2x^2+28x+96 and use the factors to find the zeros of the equation. Then, use t

gavmur [86]

Answer:

$x=-7$

Step-by-step explanation:

We have been given an equation $y=2x^2+28x+96$ . We are asked to find the zeros of equation by factoring and then find the line of symmetry of the parabola.

Let us factor our given equation as:

$2x^2+28x+96=0$

Dividing both sides by 2:

$x^2+14x+48=0$

Splitting the middle term:

$x^2+6x+8x+48=0$

$(x^2+6x)+(8x+48)=0$

$x(x+6)+8(x+6)=0$

$(x+8)(x+6)=0$

Using zero product property:

$(x+8)=0\text{ (or) }(x+6)=0$

$x+8=0\text{ (or) }x+6=0$

$x=-8\text{ (or) }x=-6$

Therefore, the zeros of the given equation are $x=-8\text{ (or) }x=-6$ .

We know that the line of symmetry of a parabola is equal to the x-coordinate of vertex of parabola.

We also know that x-coordinate of vertex of parabola is equal to the average of zeros. So x-coordinate of vertex of parabola would be:

$\frac{-8+(-6)}{2}=\frac{-14}{2}=-7$

Therefore, the equation $x=-7$ represents the line of symmetry of the given parabola.

Write the function for the following chart,

timurjin [86]

Dy/dx=1/2, 1/2, 1/2 etc

So this is a linear equation of the form y=mx+b where m=dy/dx=1/2 so

y=x/2 +b, now we can use any point to solve for the y-intercept, "b", I'll use (7,0)

0=7/2 +b

b=-7/2 so

y=x/2-7/2

y=(x-7)/2
