y = x + 5
If it's perpendicular the slope is the opposite inverse of the other line,
The slope of line y = x + 5 is 1, because it's the number before x, so, the opposite inverse would be -1/1 = -1.
Answer:
36km hr
Step-by-step explanation:
Sides of first rectangle are 12 inches and 6 inches
and sides of second rectangle are 10 inches and 5 inches
So to find the ration of sides we can do
Ratio of bases = 12/10 = 6/5
Ratio of altitudes = 6/5
Area of first rectangle = base * altitude = 12 *6 = 72 square inches
Imagine the area is 360 degrees, or
radians.
You would multiply it by (3/8) to get your answer.
4 weeks at 7 days per week = (4 x 7) = 28 days
28/-14 = - 2....so the average change is -2 per day
