The initial number was 3.915 and doubled to 7.830

Regression equation  y = 3. 915(1. 106)x

7.830=3.915(1.106)D

we have to find the value of D.

This is the concept of algebra,

suppose the initial number was x, and the new number is 2x.

The constant rate of growth is r and time is D,

Then,

what is the  function representing growth?

2x=x(r)D

from our choices the equations that represents the information above will be:

7.830=3.915(1.106)D

and

7.830=3.915(2)D

Therefore

from both equations we see the initial number was 3.915 and doubled to 7.830

Answer: slope is 0
to find the slope , you have to subtract y-es and divide them by x-es.(delta y/ delta x)
so,
(-6,-2) (-7,-2)
slope: -2-(-2)/-7-(-6)
slope:0/ -1
slope: 0
which looks on the graph like this:

Alla [95]

The statement C is true about the proportional relationship that is modeled by Peter’s equation. Peter walks at a rate of 13/4 miles per hour.

<h3>What is the equation?</h3>

A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.

The complete question is

"Peter uses the equation Y=13/4x to model the number of miles that he has walked in x hours. Which statement is true about the proportional relationship that is modeled by the peat there's the equation?

A: Peter walks a rate of 4/13 miles per hour.

B: Peter walks at a  rate of 4 miles per hour.

C: Peter walks at a rate of 13/4 miles per hour.

D: Peter walks at a rate of 13 miles per hour."

Given equation;

Y=13/4x

Where,

y represents the number of miles

x is the time period

The equation shows Peter walks at a rate of 13/4 miles per hour.

Hence statement C is true about the proportional relationship that is modeled by Peter’s equation.
