<span>To find the answer for how many cards were sold take the amount per card that she made a profit on which is $.35 multiply that by the amount she profited in one week which is $42. $.35 x $42 equals 120 cards sold.
Now that we know how many cards she sold, take that number (120 cards) and multiply is by the amount each card was sold for ($.75). 120 x $.75, which equals $90 all together before paying expenses.</span>
Answer:
a. parallel b. neither c. neither d. perpendicular
Step-by-step explanation:
Find the gradient of the line in the graph
Choose 2 coordinates, I choose (0,1) and (3,3)
Use the formula
(y2 - y1)/(x2 - x1)
(3 - 1) / (3 - 0)
2/3
Gradient of a parallel line is the same
Gradient of a perpendicular line formula m1m2 = -1
(2/3)m2 = -1
m2 = -3/2
The gradient of the perpendicular line will be -3/2
The gradient of the parallel line will be 2/3
Any other gradient will be neither parallel nor perpendicular.
