Answer:
D. 13
Step-by-step explanation:
54 ÷ 3 = 18 (your age in 5 years)
18 - 5 = 13 (your age now)
![\frac{v + 9}{3} = 8](https://tex.z-dn.net/?f=%20%5Cfrac%7Bv%20%2B%209%7D%7B3%7D%20%3D%208)
Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.
3 × (v + 9) = 8 × 3
Simplify.
3v + 27 = 24
Then, subtract both sides by 27.
3v = 24 - 27
Simplify.
3v = -3
Divide both sides by 3.
v = -1

Answer:
The coordinates of P' are (4.8,-4.8).
Step-by-step explanation:
The rule of dilation
represent the dilation with scale factor 2.4 and center at origin.
If the scale factor of the dilation is k and the center is (0,0), then
![(x,y)\rightarrow (kx,ky)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28kx%2Cky%29)
Since the scale factor is 2.4, therefore
![(x,y)\rightarrow (2.4x,2.4y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%282.4x%2C2.4y%29)
From the given figure it is noticed that the coordinates of P are (2,-2). The coordinates of P' are
![P(2,-2)\rightarrow P'(2.4(2),2.4(-2))](https://tex.z-dn.net/?f=P%282%2C-2%29%5Crightarrow%20P%27%282.4%282%29%2C2.4%28-2%29%29)
![P(2,-2)\rightarrow P'(4.8,-4.8)](https://tex.z-dn.net/?f=P%282%2C-2%29%5Crightarrow%20P%27%284.8%2C-4.8%29)
Therefore the coordinates of P' are (4.8,-4.8).
