Finding Image Points for 90° Counterclockwise Rotations
What are the coordinates of F'?
Use the work shown to find the image of point F(-1,6)
after a 90° counterclockwise rotation,
(x, y) - (-y, x)
Switch the x-and y-coordinates: (6,-1)
*
(6,-1)
(-6,1)
(-6,-1)
(6,1)
Multiply the new x-coordinate by-1: (6(-1), -1)
Simplify

abde or 1,2,4, 5 is the answer

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
