The x- intercepts shown in the table are (-2,0) and (2,0)
The y- intercept shown in the table is (0,-4)
To determine the number of possible arrangements for 6 out of 8, we should use combinations. That is

Answer: b. Combination
Answer:
C) 
Step-by-step explanation:
The formula for area is
A=pi * radius ^2
If the diameter is 40, the radius is 20
Therefore

Let x be the number of weeks; therefore, the two linear equations are

Where T stands for the punches on the tea punch card and C for the punches on the coffee punch card.
Solving by substitution. Set T=C, then

Thus, substitute the value of x=3 into the first equation,

Thus, after 3 weeks, Josiah will have the same number of punches on each card, and he will have 23 punches on each card.
