Answer:
the ratio of horizontal change compared to vertical change
Step-by-step explanations
slope = difference of y/ difference of x
rise (y) over (/) run (x)
change in y over change in x (y/x)
horizontal change (x): to vertical change (y) WRONG
Answer:
undefined
Step-by-step explanation:
A line with a slope of zero is a horizontal line parallel to the x- axis
Thus, a line perpendicular to it is a vertical line parallel to the y- axis, with an undefined slope.
Answer:
Leah has 48 marbles.
Step-by-step explanation:
Represent the number of marbles that each person has by L and D.
Leah has 28 more marbles than Dan: L = D + 28.
Then (1/3)L = (4/5)D. Here the LCD is 15, and so multiplying this equation by 15 will remove the fractions: 15(1/3)L = 15(4/5)D.
Therefore, 5L = 12D, and D = 5L/12.
Then, since L = D + 28, L = (5/12)L + 28, or
12L = 5L + 336, or
7L = 336, or
L = 336/7 = 48.
Leah has 48 marbles. That means that Dan has 20 marbles.
