one way is to solve for the invers of the first function
remembe, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f⁻¹(x)
A.
f(x)=x/2+8
y=x/2+8
x=y/2+8
x-8=y/2
2x-16=y
f⁻¹(x)=2x-16
nope, not A
B.
f(x)=3x³+16
y=3x³+16
x=3y³+16
x-16=3y³
(x-16)/3=y³
∛((x-16)/3)=y
f⁻¹(x)=∛((x-16)/3)
nope, not the same
not B
C.
f(x)=18/x-9
y=18/x-9
x=18/y-9
x+9=18/y
y(x+9)=18
y=18/(x+9)
f⁻¹(x)=18/(x+9)
correct, the answer is C
answer is C
(0,6)(1,3)
slope(m) = (3 - 6) / (1 - 0) = -3
y - y1 = m(x - x1)
slope(m) = -3
(1,3)...x1 = 1 and y1 = 3
now we sub
y - 3 = -3(x - 1) <===
Answer:
26m
Step-by-step explanation:
8m x 2 = 16
5m x 2 = 10
16m + 10m = 26m of wires
The coordinates of centroid are: (10/3, 3)
Step-by-step explanation:
The formula for calculating centroid of a triangle is:

Here (x1,y1) are the coordinates of first vertex
(x2,y2) are the coordinates of second vertex
(x3,y3) are the coordinates of third vertex
Given:
G(-2,5) = (x1,y1)
H(6,5) =(x2,y2)
J(6,-1) = (x3,y3)
Let I be the centroid of the triangle
Putting the values in the formula

The coordinates of centroid are: (10/3, 3)
