Gelneren [198K]

Jordan have $286 in his account after 1 year.

<u>Solution:</u>

Given data:

Principal (P) = $275.00

Rate of interest (R) = 4%

Time (T) = 1 year

<u>Let us first calculate the simple interest.</u>

Simple Interest Formula:

$\text {S.I}=\frac{\text {PRT}}{100}

Substitute the given values in the simple interest formula.

$\text {S.I}=\frac{275\times4\times1}{100}

    =11

Simple interest = $11

<u>Calculating the amount in account after 1 year:</u>

Amount = Principle + Simple Interest

             = $275.00 + $11

Amount = $286

Hence Jordan have $286 in his account after 1 year.

A line through the points $(2, -9)$ and $(j, 17)$ is parallel to the line $2x + 3y = 21$. What is the value of $j$?
lys-0071 [83]

Answer:

j=-37

Step-by-step explanation:

step 1

Find the slope of the given line

we have

2x+3y=21

Convert to slope intercept form

Isolate the variable y

subtract 2x both sides

3y=-2x+21

divide by 3 both sides

y=-\frac{2}{3}x+7

The slope is

m=-\frac{2}{3}

step 2

we have the points

(2,-9) and (j,17)

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute

m=\frac{17+9}{j-2}

m=\frac{26}{j-2}

Remember that

If two lines are parallel then their slope are equal

therefore

\frac{26}{j-2}=-\frac{2}{3}

26(3)=-2(j-2)\\78=-2j+4\\2j=4-78\\2j=-74\\j=-37
