5.
-0.9p+3.2=-1.7p
subtract add 0.9p to both sides
3.2=-0.8p
divide both sides by -0.8 to isolate p
-4=p
6.
-14.3=-1.4-3d
add 1.4 by both sides
-12.9=-3d
divide both sides by -3 to isolate d
4.3=d
Given:
The point (5,0) dilated by a scale factor of 3 centered at the origin.
To find:
The coordinates of image.
Solution:
If a figure dilated by a scale factor of k centered at the origin, then the rule of transformation is
![(x,y)\to (kx,ky)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%28kx%2Cky%29)
The point is dilated by a scale factor of 3 centered at the origin, then the rule of transformation is
![(x,y)\to (3x,3y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%283x%2C3y%29)
The given point is (5,0). Putting x=5 and y=0, we get
![(5,0)\to (3(5),3(0))](https://tex.z-dn.net/?f=%285%2C0%29%5Cto%20%283%285%29%2C3%280%29%29)
![(5,0)\to (15,0)](https://tex.z-dn.net/?f=%285%2C0%29%5Cto%20%2815%2C0%29)
Therefore, the image of (5,0) is (15,0).
Answer:
5 : 1
Step-by-step explanation:
From your second-grade memorization of multiplication tables, you recognize that 15 = 3×5, so you know 3 is a factor of both numbers in the ratio. To reduce the ratio to simplest form, you divide out all common factors:
15 : 3 = (15/3) : (3/3) = 5 : 1
2x^2+7x+5 you must multiply both equations by each other in the parenthesis
