Answer:
Reflection across the x-axis
Step-by-step explanation:
The points are the same, just opposite of one another. The image looks as if it is a reflection. Think of the x-axis like a puddle and the shape looking into it; try to picture the image seeing its reflection to help.
Answer:
No
Step-by-step explanation:
They are not the same size.
Let y = x^2 - 1
x^2 = y + 1
x = sqrt(y + 1)
so f^-1(x) = sqrt (x + 1) (answer)
So 15%=15/100=3/20 so
80=3/20 of a number
multiply both sides by 20/3 to clear fraction
1600/3=a number
533.33
te number is 533.3333333
False, you want to subtract in order to get rid of the 2x in both equations
