Which expression gives the distance between the points (5, 1) and (9,-6)?
o a. (5-9) +(1+6)
o b. (5-9) + (1-6)
o c. 15-9)2 + (1 - 6)?
o d. 15-9)2 + (1 + 6)?

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
