Answer:
Observe that f(x) is a continuous function when
because is a polynomial. The possible problem may occur in x=1.
Then, f(x) is discontinuous in x=1 if the limits of f to the right and the left of 1 exist and are different or if some of those limits doesn't exist.
Let's calculate the limits:


Since,
then f(x) is discontinuous in x=1.
distance = rate * time
rate = distance / time
rate = .75 miles / .666666 hours
rate = 1.125 miles per hours (.125 = (1/8) ) so
rate = 1 plus 1/8 miles per hour. answer is B
Based on the advertisement seen by Dazuri, the cost of each soccer ball is $22.50
<h3>How to find the cost?</h3>
The advertisement says that the original cost of the ball is $30 but there is a 25% discount.
The price of each soccer ball is therefore reduced by the 25% discount on the ball.
The amount that each soccer ball costs is therefore:
= 30 - ( 30 x 25%)
= 30 - 7.5
= $22.50
Rest of the question is:
Soccer balls on sale at a 25% discount. Prices go back to $30 in a week. Don't miss out.

Answer:
- 2 1/4 pounds of blueberries
Step-by-step explanation:
Blueberries - b, raspberries - x
<u>Equations as per question:</u>
<u>Eliminate b and solve for x:</u>
- 1/5x = x - 1 4/5
- x - 1/5x = 1 4/5
- 4/5x = 9/5
- x = 9/5 : 4/5
- x = 9/5 *5/4
- x = 9/4
- x = 2 1/4
The answer would be y=32/11
