8 0

Answer:

It's easy to figure it out. The equation we have is 8 = y - 9. We need to isolate y. Simply add 9 to each side of the equation to get this: 17 = y.

ANSWER: 17 = y

I just need an explanation on why I was wrong and why the correct answer is correct

Nookie1986 [14]

Answer:

9

Step-by-step explanation:

<u><em>Definition of: Coefficient</em></u>

A number used to multiply a variable.

<u><em>Example:</em></u> 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.

Variables with no number have a coefficient of 1.

<u><em>Example</em></u>: x is really 1x.

<em><u>coefficients:</u></em>

3<em>x⁴</em>+ 5<em>x²</em> + 1<em>x</em>

<u><em>sum of the coefficients:</em></u>

3 + 5 + 1

8 + 1

Given <br><img src="https://tex.z-dn.net/?f=%20log_%7B2%7D%28x%29%20%20%3D%20%20%5Cfrac%7B3%7D%7B%20log_%7Bxy%7D%282%29%20%7D%20

Naily [24]

Answer:

$\displaystyle y = x^{-\frac{2}{3}}$

Step-by-step explanation:

<u>Logarithms</u>

Some properties of logarithms will be useful to solve this problem:

1. $\log(pq)=\log p+\log q$

2. $\displaystyle \log_pq=\frac{1}{\log_qp}$

3. $\displaystyle \log p^q=q\log p$

We are given the equation:

$\displaystyle \log_{2}(x) = \frac{3}{ \log_{xy}(2) }$

Applying the second property:

$\displaystyle \log_{xy}(2)=\frac{1}{ \log_{2}(xy)}$

Substituting:

$\displaystyle \log_{2}(x) = 3\log_{2}(xy)$

Applying the first property:

$\displaystyle \log_{2}(x) = 3(\log_{2}(x)+\log_{2}(y))$

Operating:

$\displaystyle \log_{2}(x) = 3\log_{2}(x)+3\log_{2}(y)$

Rearranging:

$\displaystyle \log_{2}(x) - 3\log_{2}(x)=3\log_{2}(y)$

Simplifying:

$\displaystyle -2\log_{2}(x) =3\log_{2}(y)$

Dividing by 3:

$\displaystyle \log_{2}(y)=\frac{-2\log_{2}(x)}{3}$

Applying the third property:

$\displaystyle \log_{2}(y)=\log_{2}\left(x^{-\frac{2}{3}}\right)$

Applying inverse logs:

$\boxed{y = x^{-\frac{2}{3}}}$

Which graph shows the equation c = 10+ 3t, where c is the total cost of going to the carnival and t is the number of $3 tickets

lubasha [3.4K]

we have

$c = 10+ 3t$

where

c---------> is the total cost of going to the carnival

t---------> is the number of $\$3$ tickets purchased

we know that

<u>the domain of the function is the interva</u>l---------------> [0,∞)

Because the number of tickets can not be negative

<u>The range of the function is the interval</u>-------------> [10,∞)

Because the total cost can not be negative

using a graph tool

see the attached figure
