A small craft in Lake Ontario sends out a series of distress signals. The coordinates of the boat in trouble first signal was (42,65). The coordinates of the second signal, sent one hour later, are (55,81). A rescue boat must be sent to the location of the craft one hour from now. Assuming the second signal is the midpoint between the first signal and the rendezvous location, where should the rescue craft be sent?

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
