ANSWER:

STEP:

Absolute signs are signs that tell the number away from 0. So the absolute number cannot be negative. |x| = x. You don't know if the number was positive or negative. |-x|. |-x| is x since it tells it's x away from 0. -|x| is -x. Since the negative sign isn't in the absolute signs, you keep it as -15.

Hope this helps :D

Answer:

-15

Step-by-step explanation:

The negative is outside of the absolute value signs/lines. The absolute value is how far the number is from 0. So, it doesn't matter whether or not there is a negative sign inside of the absolute value lines it will always be positive. But, if it's outside of it, then it will be negative.

Answer:

C is (-18, 24)

Scale factor 1 1/3

A is (9, - 4 1/2) *4 1/2 is also 4.5

Step-by-step explanation:

When we take a look at image B (-24, -12) and pre image B (-18, -9),

we can work out the scale factor by

(-24/-18) and (-12/-9) both equal 4/3

So using the scale factor to go from the pre image to the image,

We can find C coordinate by multiplying pre image C by the scale factor.

C is (-13.5 x 4/3) and (18 x 4/3)

C is (-18, 24)

The scale factor is 4/3, which is the mixed numeral of 1 1/3.

To find the pre image of point A we divide the image by the scale factor

A is (12/(4/3)) and (-6/(4/3))

A is (9, - 4 1/2)

Hope this helps,

How long will it take 5000 to double in an account that pays 5.6% simple interest

Ganezh [65]

So... doubling 5000 is just 10,000, thus

$\bf \qquad \textit{Simple Interest Earned Amount}\\\\
A=P(1+rt)\qquad 
\begin{cases}
A=\textit{accumulated amount}\to &\$10,000\\
P=\textit{original amount deposited}\to& \$5,000\\
r=rate\to 5.6\%\to \frac{5.6}{100}\to &0.056\\
t=years
\end{cases}
\\\\\\
10000=5000(1+0.056t)\implies \cfrac{10000}{5000}=1+0.056t
\\\\\\
2=1+0.056t\implies 1=0.056t\implies \cfrac{1}{0.056}=t$

Answer:

b. The vertical asymptote does not change, the horizontal asymptote changes to y= -7

Step-by-step explanation:

k = -7 is a vertical shift of -7

in the transformation

g(x) = f(x) + k
