Rip van winkle has fallen asleep for a very long time.
the length of his beard (in millimeters) as a function of time (in weeks) is graphed.
graph
how long did it take each time rip van winkle's beard grew by 5 millimeters?

choose 1
2 weeks
2.5 weeks
7.5 weeks
5 weeks

For the beard to grow by 5 mm, it would take 2 weeks.

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the beard length in mm and x represent the time in weeks.

From the graph, the line passes through (0, 10) and (10, 35). Hence:

For the beard to grow by 5 mm, it would take 2 weeks.

Step-by-step explanation:

We can solve this problem by just using the given graph.

Notice that the straight line starts at , that means in week zero the beard was 10 millimeters long.

First, let's find the constant ratio of change, using two points (0,10) and (20,60)

According to the ratio, every 5 millimeter grows each 2 weeks, in other words, the ratio of growth is 2.5 millimeters per week.

Therefore, the right answer is 2 weeks.

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
