Answer:
Y-5=-8/5 (x+3)
Step-by-step explanation:
Answer:
A. Right angle -- if you multiply the slopes of 2 intersecting lines and you "-1" then the lines are perpendicular - in this case the line in quadrant 3 has a slope of "1" and the line in quadrant 4 has a slope of "-1", hence their product is "-1" and the angles formed at the intersection of the lines are right angles.
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Let's call the width of the yard x and the length x + 3½. Since we know that perimeter = 2 * (width + length) and that the perimeter must be 26 we can write:
2 * (x + x + 3½) = 26
x + x + 3½ = 13
2x + 3½ = 13
2x = 9½
x = 4
The sequence is what is wrong and
Answer:
10.5
Step-by-step explanation:
there are 2 middle values when you have an even number of data items so you must take their average
(10+11)/2 = 21/2 = 10.5
