bulgar [2K]

Answer:

The signup fee is $17

Step-by-step explanation:

we know that

The equation in point slope form is equal to

y-y1=m(x-x1)

where

m is the slope or unit rate of the linear equation

(x1,y1) is a ordered pair of the line

Let

x -----> the number of months

y -----> the total cost of a gym membership

In this problem we have

The slope of unit rate is equal to

m=\$13\ per\ month

The ordered pair is

(x1,y1)=(4,69)

substitute

y-69=13(x-4) ----> equation in point slope form

Convert to slope intercept form

y-69=13x-52

y=13x-52+69

y=13x+17 ---> equation in slope intercept form

The y-intercept is the signup fee (value of y when the value of x is equal to zero)

therefore

The signup fee is $17

11Alexandr11 [23.1K]

Answer and Step-by-step explanation:

I will be using Desmos to show you the graph.

So, draw your line from the equation, and then lightly shade the left and ride side. That middle side is where there is no solutions for -3 ≤ x ≤ -5 for y = 2x - 5.

The parts that are shaded have the solutions.

3241004551 [841]

Answer:

The radius is 0.398 feet to produce a perfect lawn for the lawnmower.

It is given that the width of the lawnmower is 2.5 feet and the length of the rope is 25 feet.

It is required to calculate the radius (R) of the pole that will produce a perfect lawn.

What is a circle?

It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).

We have,

Width of the lawnmower =  2.5 feet

Length of the rope = 25 feet

For the perfectly mowed lawn, it means the lawnmower width which is 2.5 feet must wrap the pole with radius R, mathematically:

The perimeter of the pole = width of the lawnmower

2πR = 2.5

R =  0.398 Feet     ( π = 3.14 )

Thus, the radius is 0.398 feet to produce a perfect lawn for the lawnmower.
