Answer:
60
Step-by-step explanation:
It’s congruent because both of the shapes are very similar to each other.
Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
Answer:
The scale factor of given coordinate
A is correct.
Step-by-step explanation:
We are given two coordinate O and K. The dilation with respect to origin.
![D_{O,K}(6,12)\rightarrow (3,6)](https://tex.z-dn.net/?f=D_%7BO%2CK%7D%286%2C12%29%5Crightarrow%20%283%2C6%29)
For scale factor,
![(x,y)\rightarrow (ax,ay)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Crightarrow%20%28ax%2Cay%29)
a is scale factor of coordinate.
If we divide new coordinate with old coordinate to get scale factor.
![\text{ scale factor}=\dfrac{\text{x-value of new coordinate }}{\text{x-value of old coordinate}}](https://tex.z-dn.net/?f=%5Ctext%7B%20scale%20factor%7D%3D%5Cdfrac%7B%5Ctext%7Bx-value%20of%20new%20coordinate%20%7D%7D%7B%5Ctext%7Bx-value%20of%20old%20coordinate%7D%7D)
![\text{ scale factor}=\dfrac{3}{6}=\dfrac{1}{2}](https://tex.z-dn.net/?f=%5Ctext%7B%20scale%20factor%7D%3D%5Cdfrac%7B3%7D%7B6%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
Hence, The scale factor of given coordinate
A. 3n+6. B. 3n+18. C. 2n+2+n+4. D. 2(n+6)+(n+6) E. 2(n+6)+n.
