Biologists have noticed that the chirping of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. a cricket produces 112 chirps per minute at 74 degrees fahrenheit and 179 chirps per minute at 82 degrees fahrenheit..

Step-by-step explanation:

Please consider the complete question.  

Biologists have noticed that the chirping rate of crickets of a certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 112 chirps per minute 74° F at and 179 chirps per minute at 82°F. Find a linear equation that models the temperature T as a function of the number of chirps per minute N.

We have been given two points on the line and .

First of all, we will find the slope of the line using given points as:

Now, we will points-slope form of an equation to write our required equation as:

Since we are required to write temperature T as a function of the number of chirps per minute N, so we will get:

Therefore, our required function would be  .

c. side angle side. u shares the same sides

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
