Answer:

4th option

Step-by-step explanation:

From

- x - 2y = - 4 ( add x to both sides )

- 2y = x - 4 ( add 4 to both sides )

- 2y + 4 = x , so

Substitute x = - 2y + 4 into the second equation

On the following number line, two rational numbers are graphed. Represent the two numbers as fractions (or mixed numbers) in low
Kamila [148]

The lowest number is - 3/2 or -1 1/2 as a mixed number (answer)

The we have greatest number which is 5/6  (answer) ( note there are 6 equal spaces between each integer value).

Difference between these numbers can be written as 5/6 - (-3/2)

= 5/6 - (-9/6) = 5/6 + 9/6

= 14/6

= 2 1/3  Answer

Also, difference  = 5/6 - (-1 1/2)

= 5/6 + 1 + 1/2

=  5/6 + 6/6 + 3/6

= 14/6

= 2 1/3 (answer)

Find the average rate of change of the function
viva [34]
The average rate of change from an interval from x_1 to x_2 is the change in the value of the function divided by the change in x.

\dfrac{f(x_2)-f(x_1)}{x_2-x_1}

Let's find the values of f(x_1) and f(x_2)

f(x_1)=7(2)=14
f(x_2)=7(0)=0

Average rate of change =\dfrac{f(x_2)-f(x_1)}{x_2-x_1}

= \dfrac{14-0}{2-0}=\boxed{7}

Your answer is 7. I hope this helps! :)

How do you go this 5/m = 20/32
Pani-rosa [81]
I don't know what you mean so just a guess.
5×4=20
m×4=32
32÷4=8

m=8
I would guess a teacher wants this in a more math classroom way but that is my random guess.
