Step-by-step explanation:
if I understand this correctly than you are looking for the inverse function of f(x) = y = 3x³.
the inverse function simply tries to calculate the original x it of the original y.
and then, to make it a formal function, we rename x to y and y to x.
y = 3x³
x³ = y/3
![x = \sqrt[3]{ \frac{y}{3} }](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7By%7D%7B3%7D%20%7D%20)
=> as "regular" function
![y = {f}^{ - 1} (x)= \sqrt[3]{ \frac{x}{3} }](https://tex.z-dn.net/?f=y%20%20%3D%20%20%7Bf%7D%5E%7B%20-%201%7D%20%28x%29%3D%20%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7Bx%7D%7B3%7D%20%7D%20)

Have a wonderful day!!!
Answer:
a=10, c=1.4
Step-by-step explanation:
so the ratio of the side with the length 5 to the side <em>a</em> is 1:2(or we could say a to 2a). Because of this we now multiply 2 to 5 to get a=10(because it is a 1 to 2 ratio).The relation between the side worth 2 and the side <em>c</em> is a√2 to a. so we divide √2 from 2 to get √2 and this number in decimal form is 1.41421356237....., so rounded to the nearest tenth is 1.4(because 1 rounds down)
Answer:
There is no solution to this equation.
Step-by-step explanation:
We know this because when we go to eliminate a term, both terms cancel out resulting in an incorrect statement. This makes the answer no solution.
-2x - 5y = 13
2x + 5y = -3

0 = 10
Answer:
y = - 3x + 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 3 ← is in slope- intercept form
with slope m = 
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 9 + c ⇒ c = 2 + 9 = 11
y = - 3x + 11 ← equation of perpendicular line
