Choose the variable expression that matches this phrase. the sum of the number of crew members on the tour boat and the 5
passengers.
O A. 50
O B. 5+ c
O c. 5-c
D. 5+ c

B. 5 + c

Step-by-step explanation:

The sum of the numbers of crew members is a unknown value that can be represent as c and the 5 passengers is a number that can be add to the variable. Hope it make sense.

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.
