Answer:
x = 6, y = 5
Step-by-step explanation:
When x = 6 and y = 5,
3(6) - 5 = 13
18 - 5 = 13
13 = 13
L.H.S = R.H.S
2x2 = 4
4x2 = 8
The next: 8x2 = "16"
------
16x4 = 64
64x4 = 256
The next: 256x4 = "1024"
One bag of soil is 5/8 pounds.
you have 16 of them.
just multiply 16 by 5/8.
you could just type it into your calculator, or you could do it the long way:

she has 10 pounds of potting soil.
Z=-9 I think ............
Distance Formula
d = sqrt((x1-x2)^2 + (y1-y2)^2)
d = sqrt((0-8)^2 + (0-3)^2)
d = sqrt((-8)^2 + (-3)^2)
d = sqrt(64+9)
d = sqrt(73)
You are correct. Nice work.
