What is the value of the rational expression below when x is equal to 7? ( x+13)/x-3

5

Step-by-step explanation:

7+13/7-3

20/4

5

5

Step-by-step explanation:

(x+13)/x-3 = (7+13)/7-3 = 20 / 4 = 5

no pictures of the graph

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.
