Y=9x-2
3x-2y=7
3x-18x+4=7
-15x=3
x=-1/5
y= -19/5
No, y does not vary directly with x. When y varies with x, it means that y and x always have the same ratio. Simplified, the first ratio is 1:5 and the second and third ratios simplified are 1:6. Therefore, y does not vary with x.
Answer:
p = 17/48 or 0.354
Step-by-step explanation:
11/16 = p + 4/12
subtract 4/12 from both sides
11/16 - 4/12 = p
convert so you have a common denominator
3(11/16) - 4(4/12)
33/48 - 16/48
= 17/48
p = 0.354
Slope = rise/run = 12/28 = 3/7
hence slope is 3/7 feet or 0.43 feet.
