Answer:

1. The two numbers are 4 and 8.

Step-by-step explanation:

1) variables: x and y

2) x + y = 12, y - x = 4

3) graph using desmos or another graphing calculator

4) the solution is x = 4, y = 8, or 4 and 8. This means that 4 and 8 can be added to equal 12, and the difference between them is 4.

Find the slope (8,-5) (8,10)

andreev551 [17]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =10\\y_{1} =-5\\x_{2} =8\\x_{1} =8$

^^^Plug these numbers into the formula for slope...

$\frac{10-(-5)}{8-8$

$\frac{15}{0}$

Your slope is undefined. This means that you line is vertical

Hope this helped!

Parallelogram ABCD is dilated to form parallelogram EFGH. Side BC is proportional to side CD. Which corresponding side is propor

notsponge [240]

Answer:

It is given that , Parallelogram ABCD is dilated to form parallelogram EFGH.

When Dilation of a geometrical shape takes place, the two→→image and Pre image will be Similar.

Parallelogram ABCD ~ Parallelogram EFGH

Since Similar shapes have , Proportional side Lengths as well as length of their Diagonal will be proportional.

$\frac{AB}{EF}=\frac{BC}{FG}=\frac{CD}{GH}=\frac{AD}{EH}=\frac{AC}{EG}=\frac{BD}{EG}$

So, Segment FG will be proportional to Segment BC.

Express 10.9090909091... as a rational number, in the form pq where p and q are positive integers with no common factors.

Alexeev081 [22]

Firts, Let $x$ be the repeated decimal that we are trying to convert , so $x=10.9090909090$ equation (1)

Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:
$100x=1090.90909090$ (2)

Subtract equation (1) from equation (2):
$100x-x=1090.90909090-10.90909090$
$99x=1080$

Solve for $x$
$x= \frac{1080}{99}$

We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span> $\frac{1080}{99}$ .
