Step-by-step explanation:

let Sean be 4 years old and Rachel be 2 years old on April 17

part (A)

R=S-2 --(A)

is an equation that can be used to determine Rachel's age

likewise,

S=R+2--(B)

can be used to determine Sean's age

part (B)

use equation(A) for table (1) and equation(B) for table 2

Table (1) : R=S-2=11-2= R=9

12-2=10=»R=10

13-2=11=»R=11

14-2=12=»R=12

15-2=13=»R=13

16-2=15=»R=14

likewise use equation B for the table (2)

the outputs must be 3,4,5,6,7,8

and 9

What is the answer to 2(5x+4)=8

vampirchik [111]

Answer:

So first we have 10x = 0. We divide by 10 on both sides, so then we get x = 0. We still have 0 because 0/10 = 0.

So that means that the answer is

<h2>Write 10 in the first box 10 in the second</h2><h2>x=0</h2>

The length of ZX is 2 units. What is the perimeter of triangle XYZ?

dezoksy [38]

Keywords

triangle,perimeter,distance, length, side, points

we know that

The perimeter of a triangle is the sum of the three length side

To find the length side calculate the distance between two points

The formula to calculate the distance between to points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

Step 1

Find the distance ZY

$Z(1,0)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-0)^{2}+(3-1)^{2}}$

$dZY=\sqrt{5}\ units$

Step 2

Find the distance XY

$X(-1,4)\\Y(3,1)$

substitute the values

$d=\sqrt{(1-4)^{2}+(3+1)^{2}}$

$dXY=\sqrt{25}=5\ units$

Step 3

Find the perimeter of the triangle

$P=ZX+ZY+XY$

we have

$dZX=2\sqrt{5}\ units$

$dZY=\sqrt{5}\ units$

$dXY=5\ units$

Substitute

$P=(2\sqrt{5}+\sqrt{5}+5)\ units$

therefore

the answer is

$P=(3\sqrt{5}+5)\ units$

You deposit $1500 in a stock account. The account starts losing 2.6% interest annually. How must money do you have after 2 years

Serhud [2]

Answer: M(2) = $1500*(1 - 0.026)^2 = $1423.01

Step-by-step explanation:

Initially in the acount there is $1500

You lose a 2.6% (or 0.026 in decimal form) per year, so after the first year you have:

M = $1500 - 0.026*$1500 = $1461

After other year, you lose oter 2.6%

M = $1461 - 0.026*$1461 = $1423.01

The equation can be writen as:

M(t) = $1500*(1 - 0.026)^t

Where t is the number of years, you can use t = 2 and get:

M(2) = $1500*(1 - 0.026)^2 = $1423.01

1. If a house cost $200,000 in Las Vegas in 2012 and there was a 20.7% increase in houses from 2012 to 2013, what is the price o

scZoUnD [109]

Answer:

$241,400

Step-by-step explanation:

House costs: $200,000

Percentage increase: 20.7%

This means that the cost of the house increased by that percentage from 2012 to 2013. Therefore the following,

200,000 x 20.7/100 = 41,400

So the value of the house increased by $41,400 in this year.

Now we add to evaluate the total price of the house in 2013.

200,000 + 41,400 = 241,400

House price: $241,400
