Answer:B

Step-by-step explanation: x - 1/2y = 0 just seems like the most reasonable answer.

Answer:

-x + y = 0 or x - y = 0

Step-by-step explanation:

The line passes through points (0, 0) and (4,4), then its slope is:

m = (4 - 0)/(4 - 0) = 1

Given that the line passes through (0, 0), its y-intercept is

b = 0

Using slope and y-intercept form:

y = mx + b

y = x

The standard form of a line is:

Ax + By = C

So, we have to put all variables on the left side, as follows:

-x + y = 0

Multiplying by (-1) at both sides:

x - y = 0

Find the inverse of the function. f(x) = the cube root of quantity x divided by seven. - 9
elena-14-01-66 [18.8K]
To solve

replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)

so
I'm not sure if it is
f(x)=\sqrt[3]{\frac{x}{7}}-9 or
f(x)=\sqrt[3]{\frac{x}{7}-9}


first one
f(x)=\sqrt[3]{\frac{x}{7}}-9
replace f(x) with y
y=\sqrt[3]{\frac{x}{7}}-9
switch x and y
x=\sqrt[3]{\frac{y}{7}}-9
solve for y
x+9=\sqrt[3]{\frac{y}{7}}
(x+9)^3=\frac{y}{7}
7(x+9)^3=y
replace y  with f⁻¹(x)
f^{-1}(x)=7(x+9)^3

2nd one
f(x)=\sqrt[3]{\frac{x}{7}-9}
replce f(x) with y
y=\sqrt[3]{\frac{x}{7}-9}
switch x and y
x=\sqrt[3]{\frac{y}{7}-9}
solve for y
x^3=\frac{y}{7}-9
x^3+9=\frac{y}{7}
7(x^3+9)=y
replace y  with f⁻¹(x)
f^{-1}(x)=7(x^3+9)



if you meant f(x)=\sqrt[3]{\frac{x}{7}}-9  then the inverse is f^{-1}(x)=7(x+9)^3

if you meant f(x)=\sqrt[3]{\frac{x}{7}-9}  then the inverse is f^{-1}(x)=7(x^3+9)
