$766.28

Step-by-step explanation:

The equation for interest rate is as follows:

$A = P(1 + r)^t\\$

A = The total amount

P = Initial amount

R = The interest rate

T = Time

Let's plug everything into the equation that is given in the question:

The initial amount = 612

Interest rate = 2.85

Time = 8 years

A = 612(1+.0285)^8

***Just a reminder we move the decimal over twice when working with percents***

Now, lets solve for the total amount:

$A = 612(1.0285)^8\\A = 612(1.252086602)\\A = 766.28$

Therefore, after 8 years the principal is $766.28.

I hope this helps!!

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

you for asking!

Answer from: Quest

$y> \frac{1}{3}x$ and y≤ -x +4 .

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be = $\frac{1-0}{3-0} = \frac{1}{3}$ .

y-intercept of dotted line is y=0 only.

plugging slope m= $\frac{1}{3}$ and b=0 in slope-intercept form y=mx+b, we get

$y=\frac{1}{3}x$ .

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

$y> \frac{1}{3}x$ .

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be = $\frac{4-1}{0-3} = \frac{3}{-3}=-1$ .

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

y≤ -x +4 .
Write a system of inequalities to represent the shaded portion of the graph.
