Y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value and 'm' is the slope.
y - 8 = -1.2(x - 7)
Distribute -1.2 into the parenthesis:
y - 8 = -1.2x + 8.4
Add 8 to both sides:
y = -1.2x + 16.4
Answer:
A. 41 ft / sec.
Step-by-step explanation:
28 miles per hour = 28/(60*60)
= 28 /3600 miles per second
= 28 * 5280 / 3600 feet per second
= 41 ft / sec.

The score set above has no mode
This is because mode is a measure of what score occurs the most
In this score set no numbers occur more than once
Answer: the total cost for an order of 20 copies is $13.9
Step-by-step explanation:
Let x represent the number of copies ordered.
The printing service charges a set-up fee of $12.50 for each order and 7 cents more for each copy.
The equation representing the total cost, C (in dollars), for an order of x copies is expressed as
C = 0.07x + 12.50
Therefore, the total cost for an order of 20 copies would be
C = 0.07 × 20 + 12.5
C = 1.4 + 12.5
C = 13.9 dollars
