Answer:
f⁻¹(x) = 1/2 x -3/2
Step-by-step explanation:
f(x) = 2x-3 ... y = 2x -3
replace x and y: x' = 2y' -3
solve y': y' = 1/2 x' - 3/2
f⁻¹(x) = 1/2 x -3/2
2/5 of 3 = 2/5 * 3 = 6/5....what he plants
(6/5) / 5 = 6/5 * 1/5 = 6/25 <== what each friend got
Answer:
60
Step-by-step explanation:
Since the sides are equal, the angles have to be equal
The angles of a triangle add to 180
180/3 = 60
Angle A = 60
(These steps show you how to determine whether the lines are parallel or perpendicular) -
*use the equation of straight line :
y = mx + c
