Answer:

x + 6, y - 4

Step-by-step explanation:

The original image would be the blue triangle, so you need to see how many units it takes to get to the red triangle.

Let's focus on R and R'.

You need to move 6 units to the right, and 4 units down to get from R to R'.

It would then be the same for the other two points.

Roberta has $10,540 to invest. She plans to invest her money in certificates of deposit (CDs) that have 2.1% interest, a stock p

ira [324]

Answer:

The amount invested in CDs is $1,340

The amount invested in the stock portafolio is $6,900

The amount invested in the saving accounts is $2,300

Step-by-step explanation:

Let

x ---->the amount invested in CDs at 2.1%

y ---> the amount invested in the stock portfolio at 2.5%

z ---> the amount invested in the savings account at 1.5%

$x+y+z=10,540$ ----> equation A

$z=\frac{1}{3}y$ ----> equation B

substitute equation B in equation A

$x+y+\frac{1}{3}y=10,540$

$x+\frac{4}{3}y=10,540$

$x=10,540-\frac{4}{3}y$ ----> equation C

we know that

The total interest earned by the three amount must be equal to $231.69

$0.021x+0.025y+0.015z=231.69$ ----> equation D

substitute equation B and equation C in equation D

$0.021(10,540-\frac{4}{3}y)+0.025y+0.015(\frac{1}{3}y)=231.69$

solve for y

$221.34-0.0315y+0.025y+0.005y=231.69$

$0.0015y=231.69-221.34$

$0.0015y=10.35$

$y=\$6,900$

Find the value of x

$x=10,540-\frac{4}{3}(6,900)$

$x=\$1,340$

Find the value of z

$z=\frac{1}{3}(6,900)$

$z=\$2,300$

Evaluate. Express the answer in scientific notation and decimal notation. 4x1010 5x1014

Allisa [31]

Answer:

1. $40000000000$
2. $500000000000000$
(In case you were asking me to multiply, 20 × 10^24)

Step-by-step explanation:

Given the following questions:
$4\times10^{10}$
$5\times10^{14}$

In order to find the answers, we take note on how the exponents are positive. We also need to remember how integers always have invisible decimal points.

Question one:

$4\times10^{10}$
$4\times10^{10} =4.0.0.0.0.0.0.0.0.0.0.$
$4.0.0.0.0.0.0.0.0.0.0.=40000000000$
$40000000000$

Question two:

$5\times10^{14}$
$5\times10^{14}=5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.$
$5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.=500000000000000$
$500000000000000$

In case you were asking me to multiply:

$40000000000\times500000000000000=20000000000000000000000000$
$20000000000000000000000000=20\times10^{24}$
$20\times10^{24}$

Hope this helps.
