The correct answer is option A which is x = 3.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be solved as:-

( 8x - 8 ) $^\dfrac{3}{2}$ = 64

We can write 64 as $16^{\dfrac{3}{2}}$

( 8x - 8 ) $^\dfrac{3}{2}$ = $16^{\dfrac{3}{2}}$

8x - 8 = 16

8x = 24

x = 3

Therefore the correct answer is option A which is x = 3.

Find the savings plan balance after 3 years with an APR of 7% and monthly payments of $150.

Citrus2011 [14]

Answer:

The balance is $5989.5

Step-by-step explanation:

The savings plan balance is given by the following formula:

$A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]$

In which A is the savings plan balance, P is the monthly payment, APR is the annual percentage rate(decimal), n is the number of payments per year and Y is the number of years.

In this problem, we have that

Find the savings plan balance after 3 years with an APR of 7% and monthly payments of $150.

So we have to find A when $P = 150, APR = 0.07, n = 12, Y = 3$ .

So

$A = P*\left[\frac{(1 + \frac{APR}{n})^{n*Y} - 1}{\frac{APR}{n}}\right]$

$A = 150*\left[\frac{(1 + \frac{0.07}{12})^{12*3} - 1}{\frac{0.07}{12}}\right]$

$A = 5989.5$

The balance is $5989.5

Answer:

<h2>The graph is in the attachment</h2>

Step-by-step explanation:

<, > - dotted line

≤, ≥ - solid line

<, ≤ - shaded region below a line or to the left if is a vertical line

>, ≥ - shaded region above a line or to the right if is a vertical line

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

We have x ≥ 4:

solid vertical line x = 4

#1: Solve the inequality below.<br> -3x + 5 < -19

frosja888 [35]

Explanation: Just like any of your two-step equations,

in this inequality, start by isolating the x term which in this

case is -3x by subtracting 5 from both sides.

That leaves you with -3x < -24.

To get x by itself, divide both sides by -3 but watch out.

When you multiply or divide both sides of an inequality by a

negative number, you must switch the direction of the inequality sign.

So we have x < 8 and put your final answer in

set notation and it look like this → {x: x < 8}.

<em>Find the gradient of the line joining (-1,9) and (3,5)</em>

<em /> $\dashrightarrow\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}$

Use the slope formula:-

$\boxed{\frac{y_2-y_1}{x_2-x_1}}$

Replace the letters with the numbers:-

$\boxed{\frac{5-9}{3-(-1)}}$

$\circ$ On simplification,

$\boxed{\frac{-4}{3+1}}$

$\circ$ On further simplification,

$\boxed{\frac{-4}{4}}$
