First, let's call "a number": n

Then. "eight less than a number" can be written as: n-8

This expression "is no more than 14" can be written as: n−8≤14

A linear function and its inverse are given.

jarptica [38.1K]

Answer:

x: -5, -3, 0, 1, 4

y:-23, -15, -3, 1, 13 for the function.

x:-23, -15, -3, 1, 13

y: -5, -3, 0, 1, 4 for the inverse.

Step-by-step explanation:

we know that if we have the function f(x) = y, then the inverse of f(x) (let's call it g(x)) is such that:

g(y) = x.

now we have

y=4x-3

y=(1/4)x+3/4

The only table that works for our first function is:

x: -5, -3, 0, 1, 4

y:-23, -15, -3, 1, 13

You can see this by replacing the values of x and see if the value of y also coincides.

Then, using the fact that the other table must be for the inverse, we should se a table with the same values, but where the values of x and y are interchanged.

The second table is that one:

x:-23, -15, -3, 1, 13

y: -5, -3, 0, 1, 4

(1,2) and (3,-8) in slope-intercept form

ycow [4]

Y=5x-3. First, you have to find the slope, which is 10/2 or 5/1. Then, you plug in the x and y with either of the 2 coordinates (I chose the first), and sole for the y-intercept.

in the blanks below. Find the slope of the line passing through the points (-9, 2) and (9,2). slope:

user100 [1]

I will assume that we are trying to find the slope between (-9,2) and (9, 2)

The slope's equation ⇒ $\frac{y2-y1}{x2-x1}$

Let's set the variables:

(x1, y1) --> (-9, 2)

(x2, y2) --> (9, 2)

Now let's plug them in:

$Slope = \frac{2-2}{9--9} =\frac{0}{18} =0$

Thus the slope of the line is 0.

Hope that helps!
