Answer:
rational because it's a decimal
Answer:
D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
9x - 7y = 22
x= -24-3y
9(-24-3y)-7y=22
x= -24-3y
-216-27y-7y=22
x= -24-3y
-34y=22+216
x= -24-3y
-34y=238
x= -24-3y
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
y=-7
x=-24+21
y=-7
x=-3
(x,y)=(-3,-7)

Answer:
15.03
Step-by-step explanation:
To find the distance between two points:
To find the distance between the points A and B, we plug the coordinates into the formula, in which case the distance is 15.03 to the nearest hundredth.
