Step-by-step explanation:

y9 divided by y3

\frac{y^9}{y^3}

When the base of the exponent are same and they are in division then we subtract the exponents.

\frac{y^9}{y^3}=y^{9-3}=y^6

2^3 divided by 5^2

\frac{2^3}{5^2}

The exponents of base are not same, so we cannot subtract the exponents

2^3=8 , 5^2= 25

\frac{8}{25} = 0.32 is a decimal number

2^3/5^2= .32

I couldn't get it as exponential notation, but here is the final answer

y9/y3= y3

and these two, you just divide ad regular numbers and the insert the y

Hope this helped!!!

If x = -1, what is the value of y in the equation?y = 8x3 + 12x2 - 6x - 3
Bezzdna [24]
<h3>Answer:   y = 7</h3>

Work Shown:

y = 8x^3 + 12x^2 - 6x - 3\\\\y = 8(-1)^3 + 12(-1)^2 - 6(-1) - 3\\\\y = 8(-1) + 12(1) - 6(-1) - 3\\\\y = -8 + 12 + 6 - 3\\\\y = 7\\\\

Explanation:

I replaced every x with -1. Then used the order of operations (PEMDAS) to simplify. Keep in mind that (-1)^2 = (-1)*(-1) = 1 and not (-1)^2 = -1

(HELP! I HAVE NO TIME) At 2pm, a store had sold 15 packs of toilet paper. By 5pm, the store had sold 57 packs of toilet paper. W
Novay_Z [31]

\mathrm {Hey, there!}

Let's solve your problem:

The answer would be 280%.

We know the following information:

2pm - 15 toilet paper rolls

5pm - 57 toilet paper rolls

We have to find the <u>percent rate of change.</u>

Here is how we will do this problem:

<h3><u>First, Set up a ratio:</u></h3>

Change in the quantity [15 - 57]

-------------------------------------

Original quantity [15]

57 - 15 = 42

<h3><u>Next, we will divide. the ratio.</u></h3>

Given quantity - 42

Number of packs sold at 2pm - 15

Fraction - 42/15

<h3><u>Convert the fraction to a decimal.</u></h3>

Fraction - 42/15

Decimal - 2.8

<h3><u>Make the decimal to a percent.</u></h3>

Decimal - 2.8

Percent - 28%

<u>Add a zero to the 28.</u>

<h2><u>Our answer is 280%</u></h2>

<h3></h3>

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sop
almond37 [142]

Answer:

3 groups

Step-by-step explanation:

Sopranos = 12

Altos = 9

Find the highest common factor of 12 and 9

12 = 1, 2, 3, 4, 6, 12

9 = 1, 3, 9

The highest common factor of 12 and 9 is 3

Therefore, the choir teacher can only have 3 groups

12 sopranos / 3 groups

= 4 sopranos per group

9 Altos / 3 groups

= 3 altos per group

Each of the 3 groups Will have 4 sopranos and 3 altos each

Find the sum of 5x+20 and the opposite of 20. Write an equivalent expression in standard form. Justify each step.
Artemon [7]

Do 5x + 1 instead of 5x + 20, because there was more than likely a mistype.


Now we are also looking for the reciprocal so we do (5x + 1)/20


Either that is the answer or there is something missing. If this is not the answer then there needs to be a number we can set the equation equal to
