If f(x) = one/nine x -2, what is f^-1(x)

Mathematics
1 answer:
astraxan [27]3 years ago

Answer:

f^{-1} (x)=9x+18

Step-by-step explanation:

Assuming f(x)=\frac{1}{9} x-2

What we have to do is replace f(x) with y, swap the locations of x and y, and then solve for y.

y= \frac{1}{9} x-2\\\\x=\frac{1}{9}y-2\\ \\x+2=\frac{1}{9}y\\\\y=9x+18\\\\f^{-1} (x)=9x+18

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his
evablogger [386]

Answer/Step-by-step explanation:

a. Using a point on the graph, (6, 12), and the slope of the line, we can first generate an equation in the point-slope form, given as y - b = m(x - a), where,

m = slope, and (a, b) is a point on the line.

Using two points, (6, 12) and (3, 21), let's find slope, m.

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{21 - 12}{3 - 6} = \frac{9}{-3} = -3

Using a point (6, 12) and slope, m = -3, generate an equation in the point-slope form by substituting a = 6, b = 12, and m = -3 in y - b = m(x - a).

✅Equation in point-slope form would be:

y - 12 = -3(x - 6)

Rewrite this to make it be in the slope-intercept form, y = mx + b.

y - 12 = -3(x - 6)

y - 12 = -3x + 18

Add 12 to both sides

y = -3x + 18 + 12

y = -3x + 30

✅The equation in slope-intercept form is y = -3x + 30

b. ✍️Based on the linear model, y = -3x + 30, the 30 represents b = y-intercept.

✅Therefore, it took Peter 30 mins long initially to deliver his package.

✍️Based on the linear model, y = -3x + 30, "-3" represents the slope.

✅Therefore,  Peter's delivery time decreased 3 mins per day.

Name the polynomial -2x^4-x^3*8x^2-12 by degree
Murrr4er [49]

Answer:

see below

Step-by-step explanation:

-2x^4-x^3+8x^2-12

First list by highest power to lowest power

The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial

If you really mean the multiply sign

-2x^4-x^3*8x^2-12

-2x^4 - 8x^5 -12

-8x^5 -2x^4 -12

This would be a 5th degree or quintic

What number is less than -12
Natali5045456 [20]

Hey there! Your answer is:

F.) -14

Here's why:

The higher a number goes when it's negative the smaller the number is. The higher a number goes when it's not a negative number the bigger it is.

I hope this answer helped you out! Have a great day/night :)
