The given line has a slope of -1 so the perpendicular line will have a slope of -1/1=1
y=x+5
Answer:
see below
Step-by-step explanation:
Each point moves to half its previous distance from P. It is probably easier to count grid squares on the graph than it is to do the math on the coordinates.
If you're doing the math on the coordinates, it is convenient to use P = (0, 0), then multiply each of the coordinates of A, B, and C by 1/2. For example:
A' = (1/2)A = (1/2)(8, 4) = (4, 2)
Divide 90.65 by 12.95
90.65/12.95 = 7 books
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
Multiply it out to get 5/7*1/9=5/63. This is an exact value of the product.
