To find the rate of change, also known as the slope, we can use the slope formula with these two given points.
Point 1: (20, 25)
Point 2: (50, 40)
(40 - 25) / (50 - 20)
15 / 30
0.5
The rate of change of this function is $0.50 / lb.
Hope this helps!! :)
Answer:
Step-by-step explanation:
The average rate of change over a interval is the slope m of the straight line joining the two points.
The average rate of change is 
Answer:
¼ yd
Step-by-step explanation:
2/5 - 3/20
1. Find the lowest common denominator of the two fractions.
The LCD of 5 and 20 is 20.
2. Give the fractions the same LCD
2/5 - 3/20 = 8/20 - 3/20
3. Subtract the numerators
Keep the same denominator.
8/20 - 3/20 = 5/20
4. Simplify the fraction
5/20 = ¼
The beetle crawled ¼ yd further than the spider.
: -x/2+3/2<5/2=x>-2
-x/2+3/2-3/2= -x/2<5/2-3/2=1
-x/2<1
-x/2/2= -x<1/2
-x can be transformed into -1/2x
-1/2x / -1/2=x
1/-1/2=-2

The dilation it’s increasing by is 4
If you multiply each of the sides by 4 you’ll get the sides of triangle B
