Answer:
B. (-6, -9)
D. (12, 3)
Step-by-step explanation:
y=mx+b is the format for this problem.
2/3 is m and -5 is b
The b is the y-intercept which is the point where the line crosses from one side of the graph to the other horizontally. You can see at -5, that is where that happens.
Then, to find the second point, you would move the -5 up 2 and right 3 points because the slope is 2/3.
You can then look at another point of the graph to find (-6, -9)
*Changed my answer from just B to B and D
Answer:
45
Step-by-step explanation:
The mean is calculated as
mean = 
Given the mean of 8 numbers is 41 , then
= 41 ( multiply both sides by 8 )
sum of 8 numbers = 328
Given the mean of 2 numbers is 29 , then
= 29 ( multiply both sides by 2 )
sum of 2 numbers = 58
The sum of the remaining 6 numbers = 328 - 58 = 270 , so
mean =
= 45
The mean of the other 6 numbers = 45
FOIL = First, Outside, Inside, Last
First - 2x*2x^2
Outside - 2x*(-5)
Inside - 3*2x^2
Last - 3*(-5)
Putting all of this together, we get 2x*2x^2 + 2x*(-5) + 3*2x^2 + 3*(-5), which would be option B
I think it might be B. but im not sure.
Answer:
A table that has (0,0), (-1,1), (-4, 2) and undefined for any positive x value
Step-by-step explanation:
Reflecting across the y axis just changes the x values, it makes them negative. so
has points (0,0), (1,1), (4, 2) and so on. reflecting over the y axis makes them(0,0), (-1,1), (-4, 2) and again so on.
Also good to mention in
negative x values are undefined, so flipped over the y axis positive x values are undefined.
As for the answer it doesn't look like any of those shown. The first one is close, but the x values would need to swap their signs.
