Answer:
Step-by-step explanation:
I used the following points.
x y
-10 -1
-5 -1
-1 0
0 1
1 3
2 7
3 15
From which I think the graph turns out to be y = 2^(x + 1) - 1
-6 2
0 5
1 8
2 14
From which I get y = 3*2^x + 2
You may say to me that's all well and good, but how did you do it? You have to take a few wild guesses. It also helps to know where the question came from. What were you studying when the graphs were assigned?
I don't think there is a magic bullet for figuring these out. You just have to keep on trying until you get it.
One thing is certain. You should work on the y intercept (5) and the distance above or below the x axis. The distance above the x axis is 2 which means that c = 2.
y = a*b^x + c
c is the constant above or below the x axis. You need only read the graph to get the result. a is the hardest to find, but it will be just slightly easier when you let x = 0.
a + c = 5 Since c = 2 a must be 3
Answer:
Looks like the scale factor is 1/3.
Step-by-step explanation:
<em>(In this dilation, the green image is polygon ABCDE, and the red image is polygon A'B'C'D'E'. The red image is the resulting image after said dilation.)</em>
A scale factor greater than one enlarges an image, and a scale factor between zero and one shrinks an image, so that rules out options 2 (SF = -3) and 3 (SF = 3).
A negative scale factor would end up in an image opposite the center of enlargement, so that eliminates option 4 (SF = -1/3).
So that means that the scale factor is option 1 (SF = 1/3)!
Answer:
The answer to this question is simply 6.
Step-by-step explanation:
You just need to subtract 6 from 36 to get the product of 5x6 which is 30
Answer:
I got the same question on Khan Academy. I was going to ask that too but saw that you already did. Maybe try to point it out to someone else on Brainly. Sorry that I could not help.
Step-by-step explanation:
1 ft = 12 inches
therefore, 15 inches is more then 1 ft
