Can anyone help me please? (I already posted this once but I forgot the picture)

Constant of Proportionality = 12

Explanation:

x = number of swimmers

y = number of laps

k = constant of proportionality

k = y/x

Use any row to find that k = 12

The direct proportion equation in the form y = kx turns into y = 12x. This means the number of laps is 12 times that of the number of swimmers. Put another way, each swimmer did 12 laps.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
