Answer:
x= -10
Step-by-step explanation:
-8x+10x+20=0
2x+20=0
2x=0-20
2x=-20
x=-20/2
x= -10
Answer:
x = -10
Step-by-step explanation:
8x (-10x)= 10x +20 (-10x)
subtract 10x from both sides of the equation
-2x/-2 = 20/-2
divide both sides by -2
x = -10

Answer:
H
Step-by-step explanation:
I searched it up :)
Answer:
H. {52, 72, 86, 105}
Step-by-step explanation:
Given 4 ordered pairs
The question asks for domain
The domain is the x-value of each ordered pair, and usually it is listed from least to greatest (increasing order)
Take out all of the x-values of the ordered pair 52,72,86,105
Notice that above is already in increasing order, so no further action is needed.
The domain for the situation is {52, 72, 86, 105}

Answer:
Step-by-step explanation:
1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]
= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]
= 11
2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]
= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]
= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]
= 1
3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]
= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]
= 5
4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]
= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]
= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]
= 1
5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]
= 5
6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]
= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]
= [tex]\frac{22}{7}\times \frac{7}{2}[/tex]
= 11
Now we can classify the expressions by their quotients as 1, 5 and 11.
2(9 + 4x) + 6(2 - x) = 7x. i need help asap pleasee
Step-by-step explanation:
18 + 8x + 12 - 6x = 7x
30 + 2x = 7x
30 = 7x - 2x
30 = 5x
Divide both sides by 5
X = 6
Monarch butterflies migrate from Canada to Mexico every fall. It is estimated that the butterfly travels about 82 km each day. Suppose the butterfly travels from Edmonton to El Rosario. This is a distance of about 3936 km. How many days does it take? How did you decide which operation to use?
Given:
Butterfly can travels = 82 km each day.
Total distance = 3936 km.
To find:
The number of day it takes to travel the given distance.
Solution:
Let the number of days it takes to travel be d.
Butterfly can travels about 82 km each day.
So, distance traveled by it in d days = (82d) km
Total distance is about 3936 km.
[tex]82d=3936[/tex]
To isolate d , we need to divide both sides by 82.
[tex]\dfrac{82d}{82}=\dfrac{3936}{82}[/tex]
[tex]d=48[/tex]
Therefore, the required number of days is 48.

A journalist is assigned to write a story that is 1,200 words long. To fit in the publications available space, the story's length can vary by no more than 75 words.
which word counts would be accepted by the journalist's publication?
1,100 1,125 1,290 1,260 1,300
The word count that can be accepted by the journalist's publication is 1,260.
Given,
A journalist is assigned to write a story that is 1,200 words long.
To fit in the publication's available space, the story's length can vary by no more than 75 words.
We need to find which word counts would be accepted by the journalist's publication.
1,100, 1,125, 1,290, 1,260, 1,300
Find the number of words the publication accepts.
We have,
1,200 words long.
The story's length can vary by no more than 75 words.
So,
1,200 + 75 = 1,275 words
The words can vary from 1,200 to 1,275 words.
Find the option which can be accepted.
1,100 - can not be accepted
1,125 - can not be accepted
1,290 - can not be accepted
1,260 - can be accepted
1,300 - can not be accepted
Thus the word count that can be accepted by the journalist's publication is 1,260.

-11x - 7y = -56, solve for y (must be in form y = mx + b)
Answer:
y= -11/7x+8
move variables to the right hand side and change its sign
-7y=-56+11x
change the signs on both sides of the equation
7y=56-11x
divide both sides by 7
y=8-11/7 x
reorder the terms and get y= -11/7x+8
