For the graphed exponential equation, calculate the average rate of change from x=-2 to x= 0
Answers
Answer:
3/2
Step-by-step explanation:
Rate of change is given by
f(x2) -f(x1)
-----------------
x2 -x1
We know x2 is 0 and x1 is -2
f(x2) is -1 and f(x1) is -4
-1 - ( -4)
----------
0 - -2
-1 +4
--------
0+2
3/2

4x + 2y = 20
multiply one part of the equation so that we can be able to use the process of elimination.
(-3x - y = -17)2
4x + 2y = 20
Now we have:
-6x -2y = - 34
4x+2y= 20
------------------------
-2x = -14
Divide -2 on both sides.
-2x = -14
/-2 /-2
x = -7.
=============================================
To solve for y, we just have to substitute the value of x to any of the equation given above, that we feel comfortable with. And I'm going to choose this equation: 4x + 2y = 20
4x + 2y = 20
4(-7) + 2y = 20
-28 + 2y = 20
Add 28 on both sides
-28 + 2y = 20
+28 +28
---------------------
2y = 48
/2 /2
y = 24.
The last thing you would do is to check if the answers is correct.
All you have to do is plug in the values of x and y into both equations and see if they equal to one another.
You may have to do this by yourself :P

Answer: Kayla used 2 5/24 cups of paint all together.
Step-by-step explanation:
Kayla paints a bookcase by using
1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.
She also used 3/8 cup of paint on the inside.
Therefore, the total number of cups of paint that Kayla used all together would be
11/6 + 3/8 = (44 + 9)/24 = 53/24 cups of paint. Converting to mixed fraction, it becomes
2 5/24 cups of paint
B. {(-1, 5), (-2, 6), (-3, 7)}
C. {(11, 9), (11, 5), (9, 3)}
D.{(3, 8), (0, 8), (3, -2)}

Answer: Option B
Step-by-step explanation:
A function has a rule, for each point in the domain, there can be only one point associated in the range.
This means that f(x) can have only one value y that is associated to the point x in the domain.
now, with this in mind, let's analyze the options, where the pairs are always written as (x, y)
A) Here we can see the pairs (2,3) and (2, 7), so we have the point in the domain, 2, that is associated with two different values in the range, so this relation can not be a function.
B) In this set, there are no problems because we do not have ani point in the domain with more than one value in the range, so this can be a function.
C) here point 11 has two different values in the range, so this can not be a function.
D) here point 3 has two different values in the range, so this can not be a function.
How many pages does it print per minute?

Answer:
use division
Step-by-step explanation:
this question is pretty simple, all you need to do is the opposite of multiplication, which is........division.
so divide 28 by 8 = 3.5
so it prints 3.5 (3 and a half) pages per minute.
