Biologist have found The number of shirts some crickets make per minute is related to temperature. The relationship is very close to being linear. When crickets chirp 124 times a minute it is about 68°F. When they charge 172 times a minute it is about 80°F

Step-by-step explanation:

Let y be the number of chirp and x be the temperature.

Given:

When crickets chirp 124 times a minute = 68°F

When crickets chirp 172 times a minute = 80°F

Solution:

Standard linear equation is written as:

Where:

y = Number of chirps

m = Temperature

From the above statement, crickets chirp 124 times a minute it is about 68°F. When they chirp 172 times a minute it is about 80°F

So, the equation is written as:

----------(1)

----------(2)

Substitute equation 1 from equation 2.

x = 4

Now, substitute x = 4 in equation 1 for value of b.

b = -148

Now we substitute x = 4 and b = -148 in equation 1.

Therefore, the relation between cricket chirp and its temperature is given by below equation.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
