The equation would look like
Y=-4x+7
Y=mx+b
7. y = 1, AB = 1, BD = 10 and AD = 11
8. x = 5, AB = 20 and BC = 20
9. x= 5 and AB = 33
10. No, because AC = 12.5 while AB + BC = 20 (they should equal the same and they don't.)
3*2*6 is 36 yards cubed or 36 yards to the power of 3.
1) 1 + 1 = 2
2) 1 - 1 = 0
3) 1 * 1 = 1
4) 1 / 1 = 1
Hope this helps!
1/r = (3 1/2)/245
(3 1/2)r = 245
r = 245/3 1/2
r = 70
scale is 1 in to 70 miles.
