Consider the two functions described below.

function 1 is represented by the graph below. it shows the distance carl travels y in x hours at a constant speed.

function 2 represents the following scenario: the equation y = 25x gives the distance y sheila travels in x hours.

which is a correct description of how to compare the rates of change in each scenario?
a. compare the change in x over the change in y for each function.
b. compare the change in y over the change in x for each function.
c. compare the values at which the graphs cross the x-axis.
d. compare the values at which the graphs cross the y-axis.

B.Compare the change in y over the change in x for each function.

Step-by-step explanation:

Find the rate of change [slope]:

-y₁ + y₂\-x₁ + x₂ = m

Change in y\Change in x

y = 40x

By the definition of slope, you have your answer.

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
