You add the time she already drove (15+10) and get 25
56-25 = 31 minutes left.
Now if the 56 minute trip includes the stop at the store, we are OK with that answer. If not, then we have to know how long she stopped at the store and add it onto 31 minutes.
Answer:
Slope= 1/3
Step-by-step explanation:
find any 2 random points. Find the height difference and put it as the numerator of a fraction. Find the distance horizontally and put it as the denominator of the same fraction.
Let's use (10, 60) and (40, 70)
40-10=30 (denominator
70-60=10 (numerator)
10/30 (simplify)
1/3

Answer: Yes, y does vary directly with x.
Constant of variation = 1/4
The function rule is y = (1/4)x
=========================================================
Explanation:
Let's assume that y does vary directly with x.
If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.
Solving for k gets us k = y/x
For each row, divide the y value over the x value
- row one: k = y/x = 14/56 = 0.25
- row two: k = y/x = 20/80 = 0.25
- row three: k = y/x = 22/88 = 0.25
Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.
So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x
