Two functions are represented in different formats.
function 1:
let x = number of hours worked
let y = total pay in dollars
y = 20x + 15

function 2: a babysitting club charges a $25 flat rate and $10 for each hour.

which statements are true?

select each correct answer.

function 1 has a greater rate of change than function 2.

function 2 has a greater rate of change than function 1.

function 1 has a greater y-intercept than function 2.

function 2 has a greater y-intercept than function 1.

function 1 has a greater rate of change than function 2.

function 2 has a greater y-intercept than function 1.

Step-by-step explanation:

Function 1 is given by: y=20x+15

and Function 2 is given by:y=10x+25

as we know that the rate of change of an equation is the same as the slope of an equation and the slope of the general form of the equation of the type y=mx+c is given by 'm'.

for function 1 the slope is:20

and for function 2 the slope is:10

so the slope of function 1 is greater than the slope of the function 2.

Hence function 1 has greater rate of change than function 2.

also the y-intercept of a line is the value of y for which x=0.

for function 1 when x=0 y=15

and for function 2 when x=0 y=25.

Hence,  the y-intercept for the function 2 is greater than that of function 1

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
