ANSWER
The coordinates of the image are (2,2)
EXPLANATION
The mapping for a reflection across the line y=k is :
![(x,y)\to (x,2k-y)](https://tex.z-dn.net/?f=%28x%2Cy%29%5Cto%20%28x%2C2k-y%29)
We want to find the image of the point (2,-4) after a reflection in the line y=-1.
In this case k=-1.
![(2, - 4)\to (2,2( - 1)- - 4)](https://tex.z-dn.net/?f=%282%2C%20-%204%29%5Cto%20%282%2C2%28%20-%201%29-%20-%204%29)
This simplifies to,
![(2, - 4)\to (2, - 2 + 4)](https://tex.z-dn.net/?f=%282%2C%20-%204%29%5Cto%20%282%2C%20-%202%20%2B%204%29)
![(2, - 4)\to (2, 2)](https://tex.z-dn.net/?f=%282%2C%20-%204%29%5Cto%20%282%2C%202%29)
Hence the image is (2,2)
4,680 I do it like this 50 percent is 3600 then 10 percent is 720 and 5 percent is 360 add then you get 4,680
Answer:
Step-by-step explanation:
Answer:
<h2>f(x) = 4</h2>
Step-by-step explanation:
f(x) = 2x
When x = 2
Substitute the value of x into f(x)
That's
f(2) = 2(2)
= 4
