Answer:

Every 60 days.

Step-by-step explanation:

This is very similar to a sequence.

try starting out with:

Abe: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21

Barb: 2, 4, 6, 8, 10

Carl: 3, 6, 9, 12

Dee: 4,8, 12, 16, 20, 24, 28, 32, 36

Earl: 5, 10, ....

so If today they all worked together....

We need a common multiple of 5, 4, 3.... so it is 60

It appears that it will be in 60 days

Leviafan [203]

Answer:

Line 1: $\infty$

Line 2: $-\frac{4}{3}$

Line 3: $\frac{4}{3}$

Line 4: $\infty$

Line 5: $\frac{7}{4}$

Line 6 : $-\frac{7}{3}$

Line 7: 0

Line 8: 0

Line 9: $\infty$

Line 10: $\infty$

Line 11: 0

Line 12: $\infty$

Step-by-step explanation:

Slope of line is given by the formula:

$\text{Slope = }\dfrac{\text{Change in } y\text{ coordinate}}{\text{Change in } x\text{ coordinate}}$

Line 1:

The change in $x$ coordinate is zero.

Therefore slope of line 1 is $\infty$ .

Line 2:

Change in $y$ coordinate = -4

Change in $x$ coordinate = 3

Slope = $-\frac{4}{3}$

Line 3:

Change in $y$ coordinate = 4

Change in $x$ coordinate = 3

Slope = $\frac{4}{3}$

Line 4:

The change in $x$ coordinate is zero.

Therefore slope of line 4 is $\infty$ .

Line 5:

Change in $y$ coordinate = 7

Change in $x$ coordinate = 3

Slope = $\frac{7}{3}$

Line 6:

Change in $y$ coordinate = -7

Change in $x$ coordinate = 3

Slope = $-\frac{7}{3}$

Line 7:

Change in $y$ coordinate = 0

Slope = 0

Line 8:

Change in $y$ coordinate = 0

Slope = 0

Line 9:

The change in $x$ coordinate is zero.

Therefore slope of line 9 is $\infty$ .

Line 10:

The change in $x$ coordinate is zero.

Therefore slope of line 10 is $\infty$ .

Line 11:

The change in $y$ coordinate is zero.

Therefore slope of line 11 is 0.

Line 12:

The change in $x$ coordinate is zero.

Therefore slope of line 12 is $\infty$ .
