Answer:
Option c.
Step-by-step explanation:
Given,
f(x) = y = 3x^6
To find f^-1(x), we just need to replace y with x, and x with y
x = 3*y^6
Now we solve for y
f(x)^-1 = y = ±(x/3)^(1/6)
To quickly see if it is a function, we can plot it using an graphing calculator or any plotting tool.
Please see attached picture.
By looking at the plot, we can tell f(x)^-1 is not a function, because for a single value of x, there are two corresponding values of y
Correct answer:
Option C.
Answer:
=4x^2−20xy+25y^2
Step-by-step explanation:
(2x−5y)^2
=(2x+−5y)(2x+−5y)
=(2x)(2x)+(2x)(−5y)+(−5y)(2x)+(−5y)(−5y)
=4x^2−10xy−10xy+25y^2
=4x^2−20xy+25y^2
Hope it helped!
Answer:
£2909.84
Step-by-step explanation:
184×12=$2208 for 12 nights at the hotel
6×9=$27 for 9 days of wifi
27×6=$162 for 6 taxi rides
Add all of them you get $2397, then convert that to £ you get £1309.84, now add the flight costs and your final answer should be £2909.84
Your equation is y=-2x+5. First find the slope by plugging two points into the slope equation y2-y1 over x2-x1. This then gets you the slope of -2. Then find the point where x=0, which then gets you your y intercept or the b value in the equation. With the slope as m and y intercept as b, we can find that in the equation y=mx+b with the new values plugged in y=-2x+5.
