What is the image of the point (5,-4) after a rotation of 90° counterclockwise about the origin?

(4,5)

Step-by-step explanation:

Rotating a point by 90 degrees counterclockwise would make the y become x and switch it's negative/positive value, and make x the y.

Ex: (x,y) would become (-y,x)

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
