Is e just an algebraic expression or is it Euler's number (2.718...)?
If e is an algebraic expression then there it is
Answer:
41. f⁻¹(x) = -9x + 4
43. m⁻¹(x) = ∛(x-2)/4
Step-by-step explanation:
41. y = (4-x)/9
swap x and y: x = (4-y)/9
solve y: 9x = 4-y
y = -9x + 4
45. y = 4x³+2
x = 4y³+2
4y³ = x-2
y³ = (x-2)/4
y = ∛(x-2)/4
Let you do 42 and 46 by yourself
20*1.95 =39 girls
26girls/39girls =0.667
0.667*100 = 66.67%
