Answer:
1/9 lbs
Step-by-step explanation:
1/3 ÷ 3
covert whole number to fraction
1/3 ÷ 9/3
copy dot flip
1/3 × 3/9
3/27
1/9
There is a really easy way to do this problem and that is to use a graphing website
after punching in the functions:
A. depending of whether it is -5/(2x) or (-5/2)x: intersecting but not perpendicular or parallel
B. These two lines are perpendicular
C. Parallel lines
D. intersecting but not perpendicular
Answer:
3 milkshakes and 3 sundaes
Step-by-step explanation:
3 * 5 = $15 + 3 * 2 = $21
If you use rise/run, the answer is 3/4. Up 3, over 4
Domain restrictions are values of x which are not acceptable in a function.
They may be arbitrary because we simply want to ignore them. eg y = x^2 between 0 and 4
They may make no sense in the context, eg graph a compounding investment over next 20 years.
Negative values for x make sense here.
They may avoid mathematical impossibilities eg y = (x^2 - 4x) / (x - 4) which must avoid dividing by zero, so x cannot = 4.
The graph will look like the line y = x but have a hole where x= 4
