Answer:
b) 1
Step-by-step explanation:
The average rate of change on an interval is given by the rise on the interval divided by the run (the width of the interval). Here, the end points are ...
(5, -3) and (8, 0)
The rise is 0-(-3) = 3. The run is 8 -5 = 3. The ratio of rise to run is 3/3 = 1.
The average rate of change on [5, 8] is 1.
Linear function equation is Y= 1/3x-4
150/4 = 37.5cm. You divide by four because there are four sides on a rectangle. But 37.5 is the cm of a square. Since it says one of the sides is 15cm greater, you subtract 37.5 - 15 = 27.5cm on 2 of the width. While the other 2 lengths are greater than the width by 15 cm, so you add 15 to 37.5 which gives you 52.5cm. So the 2 width are 27.5cm and the length is 52.5cm.
