In places where there are crickets, the outdoor temperature can be predicted by the rate at which crickets chirp. One equation that models the relationship between chirps and outdoor temperature is f=14c+40, where c is the number of chirps per minute and f is the temperature in degrees Fahrenheit. Which statements are true? Select all that apply.

Step-by-step explanation:

This question requires a list of options.

Since, there are none; I'll give a general explanation to answer this.

We have that:

[tex]f = 14c + 40[/tex]

The general format of an equation in terms of f and c is:

[tex]f = mc + b[/tex]

Where

[tex]m = slope[/tex] and [tex]b = y\ intercept[/tex]

A true statement about the function above is:

The slope of the equation is 14

This means that at every minute, there's an additional 14 chirps from the cricket.

Another true statement about the function is that:

The y intercept is 40.

This means that the initial number of chirps by the cricket is 40

i.e. At time, c = 0 minutes.

There are 40 chirps.

A likely question could be to determine the number of chirps in (say) 5 minutes.

This means that:

[tex]c= 5[/tex]

Substitute 5 for c in [tex]f = 14c + 40[/tex]

[tex]f = 14 * 5 + 40[/tex]

[tex]f = 70 + 40[/tex]

[tex]f = 110[/tex]

This implies there are 110 chirps in 5 minutes

Answer:

:)

Step-by-step explanation:

I think you men 1/4 because I have the same problem

f=1/4c+40

f=1/4(110)+40

f=27 1/2 +40

f=67 1/2
