Find the inverse of g(x) = 2x^3 +3<br><br> Step by step working please I want to learn

malfutka [58]

Set g(x) as y. Then you get y = 2x^3 + 3. Switch Y with X and you get x = 2y^3 + 3. Now you can put everything with x getting, y = cuberoot[(x-3)/2]

What is the slope of a line that is perpendicular to the line represented by the equation y=-2/5x+4/5

enot [183]

Answer:

$\frac{5}{2}$

Step-by-step explanation:

recall for a line whose equation is

y = mx + b,

the slope of this line is m

the slope of a line that is perpendicular to this line is - $\frac{1}{m}$

in this case,

m = - $\frac{2}{5}$

hence - $\frac{1}{m}$ = $\frac{5}{2}$
