Answer:
3 hours
Step-by-step explanation:
We can solve using ratios
18 lbs 12 lbs
------------ = --------------
4.5 hrs x hours
Using cross products
18x = 12 * 4.5
18x = 54
Divide by 18
18x/18 = 54/18
x=3
Answer:
what type
Step-by-step explanation:
Answer:
yes, you did
Step-by-step explanation:
When it's x= a number the line is vertical and when it's y= a number it's horizontal.
3.65 is less than 
First, you must change the mixed number into a decimal so you can compare the two numbers.

Then, you must compare the terms.
3.65 < 3.75
3.65 is less than 
Distance from the point (x,y) to the focus = distance of (x,y) from the directrix
so we have
sqrt [(x - 2)^2 + y2] = 12 + y
squaring both sides
x^2 - 4x + 4 + y^2 = 144 + 24y + y^2
x^2 - 4x + 4 = 144 + 24y
24y = x^2 -4x - 140
y = x^2/24 - x/6 - 35/6 is the required equation
