The answer is 1.496 times 10^9
Explanation: When there are two parallel lines, these two lines are never able to intersect or touch. Perpendicular lines are two lines in which one of the lines intersects the other line, and the angles created from the intersection of these two lines are all right angles.
To solve this problem you must apply the proccedure shown below:
1. By definition, the rate of change of a linear function is the slope of the line and it is constant. Based on this, you must find the slope of the given function.
2. You have the equation of the line has the following form:

Where
is the slope and
is the y-intercept.
3. Then, you have that the slope of the function
is:

Therefore, the answer is: 
Answer:
$30
Step-by-step explanation:
-One week has 7 days, so the total number of eggs laid by both chickens:

-One doze is equivalent to 12 items. There's only one full dozen unit in 21 pieces.

Hence, she makes $30 in week one.
