If f(x) and its inverse function, F(x), are both plotted on the same coordinate plane, what is their point of intersection?

polet [3.4K]

Answer: d) (3, 3)

<u>Step-by-step explanation:</u>

Inverse is when you swap the x's and y's.

Let's look at the points and find their inverse:

f(x) f⁻¹(x)

(0, -2) --> (-2, 0)

(1, -1) --> (-1, 1)

(2, 0) --> (0, 2)

(3, 3) --> (3, 3) f(x) = f⁻¹(x) so this is where they intersect!

What is y=\dfrac{2}{3}x+4y=

lara [203]

Answer:

$12y+x-12=0$

Step-by-step explanation:

If I'm not mistaken by the question, we have

$x+4y=\dfrac{2}{3}x+4$

Multiply through by the LCM of all the denominators to clear the fractions. Since we have only one fraction, we multiply through by its LCM (3)

$3\timesx+3\times4y=3\times\dfrac{2}{3}x+3\times4$

$3x+12y=2x+12$

Putting all terms on the LHS (left hand side) and evaluating,

$12y+x-12=0$

Solve the formula C = πd for d

REY [17]

Answer:

$d = \frac{C}{\pi}$

Step-by-step explanation:

$C= \pi d\\$

Isolate d ; Divide both sides of the equation by $\pi$

$\frac{C}{\pi} = \frac{\pi d}{\pi }$

Simplify

$\frac{C}{\pi} = d\\\\d = \frac{C}{\pi}$

Note; Another formula for d(diameter) =

$2\times radius$
