Answer:
2
Step-by-step explanation:
f(-1)=2(-1)+2+1
f(-1)=-2+2+1
f(-1)=1
f(0)=2(0)+2+1
f(0)=0+2+1
f(0)=3
Use slope formula for the average rate of change.
(y2-y1)/(x2-x1)
(3-1)/(0+1)
(2)/(1)

Hope this helps!
If not, I am sorry.
The function is decreasing from -6 to -3, that is, on the interval (-6,-3), and again on the interval (1, infinity).
The function is increasing on (-3,1).
No local or absolute minimum.
(1,4) is an absolute max.
Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.
Answer:
her average speed is 16 miles per hour
Step-by-step explanation:
do 48 divided by 3 = 16
3x(x²-5)
Multiply the bracket by 3x
(3x)(x^2)=3x^3
(3x)(-5)=15x
Answer: 3x^3+15x
