Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
Answer:
The value of x can be 5 or 2
Step-by-step explanation:
In given triangle ABC
Interior Angle A = 
Interior Angle B = 
Exterior Angle I = 
We know that
Exterior Angle of triangle is summation of corresponding opposite angles
Angle I = Angle A + Angle B






The beach ball is 5 times greater than the given toy ball.
Answer:
70 degrees
Step-by-step explanation:
total angle in a triangle is 180 degrees
180-40= 140
Angle b and c is total of 140 degrees
they are isosceles so their measurements would be same.
angle b and c is 140÷ 2 = 70
so angle b is 70 degrees
Just subtract the two in your head and the answer would be 45 by the way
