Answer:
f^-1(x) = (x/8)^(1/5) is a function
Step-by-step explanation:
The inverse of a function is the function reflected across the line y=x. This results in the coordinate points (x,y) of the function becoming (y,x) for the inverse function. Algebraically to find the inverse, switch the x and y locations and solve for y.
y = 8x^5
x = 8y^5
x/8 = y^5
(5)√(x/8) = y
This is a fifth root of (x/7) also written in exponents as y = (x/8)^(1/5).
This is a function. While it appears not to be a function because the middle portion over the origin appears vertical, it is a function because the middle portion over the origin is changing and graphing software shows it has no input with more than one output. Without graphing software you would rule it is not a function.
the one that equals 4cm on the other figure equals 10 Answer:
i think its 17.5 or 7.5
Step-by-step explanation:
if not let me know but i ended up with 1.5 and .5 so either or but again if not let me know
the top has a length of 7.5
the very right side of 10
the one on the top left of 17.5
the left side has a of 20
Step-by-step explanation:
3d + 5p=9.50
2d + 5p=8
1 hot dog cost $1.50
2 × 1.50 + 5p = 8
3 + 5p = 8
5p = 8 - 3
5p = 5
p = 1
1 bag of potato chips cost $1.00
Answer:
Step-by-step explanation:
1. Multiply both sides by 3.
2. Simplify 3 × 7 to 21.
therefor, the answer is x < -21
