Answer:
The answer is last option
As we know 1 + tan^2 = sec^2
What does the eliminate mean?
Answer:
A rate of 5/2 means that:
If we move 2 units to the right, we move 5 units up.
Let's see all the graphs, the easier way to know this is:
In any point of the line, move to the right 2 units.
Then from that point, move up until you meet again with the line, if you moved 5 units, then the slope is 5/2.
A) The slope is 5/2.
B) The slope is 4/2
C) the slope is 5/2
I can not see very well graphs E and D in the image.
E) may have a slope of 5/2, you should measure it.
D has not a slope of 5/2, you can compare it with A and see that is totally different, so you can discard option D.
Answer:
New image will have (2,1) , (-2,0) and (-2,-2) as new vertex.
Below is the graph.
Step-by-step explanation:
Given the triangle with points (4,7) , (-8,4) and (-8,-2) having dilation center at (1,-2) .
We have to dilate using a factor of 1/3 and graph the new image.
Let us find all the three points,
Formula,
New point = [old point - dilation center]* scale factor + dilation center
So,
For (4,7)
![[(4,7)- (1,-2)]*\frac{1}{3} + (1,-2)](https://tex.z-dn.net/?f=%5B%284%2C7%29-%20%281%2C-2%29%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%20%281%2C-2%29)
![[3,9]*\frac{1}{3} +(1,-2)](https://tex.z-dn.net/?f=%5B3%2C9%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%281%2C-2%29)
![[1,3]+(1,-2)= (2,1)](https://tex.z-dn.net/?f=%5B1%2C3%5D%2B%281%2C-2%29%3D%20%282%2C1%29)
For (-8,4)
![[(-8,4)- (1,-2)]*\frac{1}{3} + (1,-2)](https://tex.z-dn.net/?f=%5B%28-8%2C4%29-%20%281%2C-2%29%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%20%281%2C-2%29)
![[-9,6]*\frac{1}{3} +(1,-2)](https://tex.z-dn.net/?f=%5B-9%2C6%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%281%2C-2%29)
![[-3,2]+(1,-2)= (-2,0)](https://tex.z-dn.net/?f=%5B-3%2C2%5D%2B%281%2C-2%29%3D%20%28-2%2C0%29)
For (-8,-2)
![[(-8,-2)- (1,-2)]*\frac{1}{3} + (1,-2)](https://tex.z-dn.net/?f=%5B%28-8%2C-2%29-%20%281%2C-2%29%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%20%281%2C-2%29)
![[-9,0]*\frac{1}{3} +(1,-2)](https://tex.z-dn.net/?f=%5B-9%2C0%5D%2A%5Cfrac%7B1%7D%7B3%7D%20%2B%281%2C-2%29)
![[-3,0]+(1,-2)= (-2,-2)](https://tex.z-dn.net/?f=%5B-3%2C0%5D%2B%281%2C-2%29%3D%20%28-2%2C-2%29)
Therefore these (2,1) , (-2,0) and (-2,-2) are the new vertices after dilation.
The answer is d, because you have to multiply the price by the percentage off.
