Answer:
Sam workrate 1/5
Lucy workrate 1/3.5 = reciprocal of 7/2 = 2/7
combined workrate: 1/5 + 2/7 = 17/35
they will mow the lawn in 35/17 = 2 and 1/17 hours
2 hours 3 1/2 mins
Step-by-step explanation:
So first divide the equation on both sides by 3. We get

. Slope-y-intercept form is of the form

. Rearranging

, we get

. Divide by two, we get

, which is of that form.
Graphing: The y intercept is at -2, and the slope is 1/2.
a) The equation of axis is the middle y-coordinate, which is y = -1.5.
b) The period is the amount of time it takes for the graph to repeat, which is 6.
c) The amplitude is the vertical distance from an extreme point to the midpoint, which is 3.
d) This is a cosine graph since when x=0, y is not equal to 0.
Answer:
60%
Step-by-step explanation:

Given:
- value = 24 votes
- Total value = 40 members
