First plot the points. Let’s just use the first graph. When you have done that. Draw a triangle. Find the right angle and look at what line is across from that. That is the hypotenuse. That is the length that you are trying to find. So you have to do your equation: a^2 + b^2 = c^2. A and B have to be the length of the other 2 lines(just count it). When you have done that repack you a and b with your #s. And what ever is equal to you c. Then that is you answer. (Im sorry if this was confusing)

How do i answer this question?

blondinia [14]

Answer:

$f^{-1}$ (59) = 20

Step-by-step explanation:

$f^{-1}$ (x) is the inverse of f(x)

to find the inverse function, let f(x) = y and rearrange to make x the subject.

y = 3x - 1 ( add 1 to both sides )

y + 1 = 3x ( divide both sides by 3 )

$\frac{y+1}{3}$ = x

change y back into terms of x with x = $f^{-1}$ (x) , then

$f^{-1}$ (x) = $\frac{x+1}{3}$ , then

$f^{-1}$ (59) = $\frac{59+1}{3}$ = $\frac{60}{3}$ = 20

What are the roots of the polynomial equation? x2+6x−72=0

Fantom [35]

⇒Δ=6^2+4*72= 36+288=324
V324=18

x1= ( -6+18)/2=6
x2= (-6-18)/2=-24/2=-12

⇒ x1= 6
x2= - 12
