.Bryan was given the equation y= -5x+3. He says the rate of change is 3 and the initial value is -5. Is Bryan correct? If not, c
Mekhanik [1.2K]

Answer:

Correct rate of change is -5; correct initial value is 3.

Step-by-step explanation:

The rate of change is the coefficient of the x term, which here is -5.  So Bryan has the rate of change wrong.

The initial value of the function is found by letting x  =  0.  Here, we get

y = -5(0) + 3, or y = b = 3.  The initial value is 3, not -5.

C = 172.7 cm
Anika [276]
I am hoping that the a in c = ad is supposed to be x.

The formula for circumference is c = pi * diameter with 3.14 substituting for pi.

Let’s plug in some values

172.7 = 3.14d

Divide

55 = d

The diameter should be 55 cm.
