Area of rectangle = Length*width
A = 28 so 28 = 4 * height
height = 28/4 = 7
A relation is a function, if and only if, the x- values do not repeat in a given set.
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
The answer is
13.76 because when u multiply negative times negative it gives u a positive
Step-by-step explanation:
high: 91, 91, 91, 91, 90, 90, 92, 94
low:59, 60, 60, 60, 60, 60, 60, 61
