Answer:
D. Both functions are decreasing at the same average rate on that interval
Step-by-step explanation:
The dashed lines on the attached graph of the two functions (f in red, g in purple) represent the average rate of change of each function on the interval. The lines are parallel, because the average rate of change is the same for each of the functions on that interval.
__
Function f decreases by 60 units from f(0) = 64 to f(4) = 4 on the interval x = [0, 4]. Function g decreases by 60 units from g(0) = 75 to g(4) = 15 on the same interval. The average rate of change is the amount of decrease divided by the interval width. Those values are the same for both functions.
Answer:
Slope= 2 / 10 = 1 / 5 = 0.2
y-intercept= (0, -4/5) or (0, -0.8)
Step-by-step explanation:
Answer:
(7,4)
Step-by-step explanation:
Use the midpoint formula:
(x1+x2/2,y1+y2/2)
Sub in the points
9+5/2,2+6/2
7,4
Final answer:
(7,4)
Hey there! I’m happy to help!
Let’s use the variable g to represent the girls. This ratio shows that there are twice as many boys as girls (boys=2g)We also see that there are 18 more boys that girls. Let’s set up an equation
g+18=2g
We subtract 18 from both sides
g=2g-18
We subtract 2g from both sides.
-g=-18
We divide both sides by -1
g=18
Therefore, there are eighteen girls.
I hope that this helps! Have a wonderful day!
