Find the length of AM.

AM = 26

Step-by-step explanation:

AM = MC

x+20 = 5x-4

Subtract x from each side

x+20-x = 5x-x-4

20 = 4x-4

Add 4 to each side

20+4 = 4x-4+4

24 = 4x

Divide by 4

24/4 = 4x/4

6 =x

We want AM

AM = x+20

       =6+20

      =26

26

Step-by-step explanation:

x+20=5x-4

x+24=5x

24=4x

x=6

x+20

substitute 6 for x

6+20

26

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.
