Answer: x + 7/2
Explanation:
1/2(2x + 7) = x + 7/2
Answer:
B -4/5
Step-by-step explanation:
The slope of line D is given by
m = (y2-y1)/(x2-x1)
= (6-1)/ (5-1)
=5/4
We want the slope of the line perpendicular
That would be the negative reciprocal
- (4/5)
Answer:
3/2 cm/s
Step-by-step explanation:
speed = gradient of the line (slope)
To calculate the slope divide the change in y by the change in x:
(9 - 0) / (6 - 0) = 9/6 = 3/2 cm/s
The formulas for the perimeter and area of a square may be derived from the corresponding formulas for a rectangle because, like rectangles, squares are quadrilaterals, therefore sharing the same formal characteristics as a rectangle. They both contain a pair of lengths and a pair of widths, giving us 2-dimensional figures on a plane.
