The correct answer is (1,2)
Steps:
Multiply the second equation by 6 in order to eliminate the x variable.
6x-7y= -8
6(-x-4y= -9)
6x-7y= -8
-6x-24y=-54
Add the equations together and solve for y
-31y= -62
Y=2
Substitute y=2 in the original equation
-x-4(2)= -9
-x-8= -9
-x= -1
X=1
Answer: (1,2)
Given :
In 2006, 65.2 million people subscribed to cable television.
In 2013, that number had decreased to 54.2 million.
To Find :
The percent decrease in the number of cable TV subscribers from 2006 to 2013.
Solution :
Decrease in the number of cable TV subscribers from 2006 to 2013 is :
Therefore, percentage decrease is 16.87 %.
The distributive property:
a(b + c) = ab + ac
2(x - 8) = 68
(2)(x) - (2)(8) = 68
2x - 16 = 68 |+16
2x = 84 |:2
x = 42
Answer: D. 42

6
Step-by-step explanation:
2,400 divided by 400 = 6
There is no question context so it is not sufficient for an answer, however I am assuming its asking for you based on the images to pair the charts to graph.
First lets find the slope of (20,-1) (21,-1.5)
<u>-1+1.5
</u>20-21<u>
</u>The slope for that chart is 0.5/-1 which is -0.5 or -1/2. This makes that chart paired with the following graph:
