What is the average rate of change of the function
f(x) = 2x + 8
over the interval [2, 6)?
Answers
The average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.
Important information:
The function is [tex]f(x)=2x+8[/tex].The given interval is [2,6].Average rate of change:The average rate of change of the function f(x) over the given interval [tex][a,b][/tex] is:
[tex]m=\dfrac{f(b)-f(a)}{b-a}[/tex]
Using the above formula, we get
[tex]m=\dfrac{f(6)-f(2)}{6-2}[/tex]
[tex]m=\dfrac{(2(6)+8)-(2(2)+8)}{4}[/tex]
[tex]m=\dfrac{12+8-4-8}{4}[/tex]
[tex]m=\dfrac{8}{4}[/tex]
[tex]m=2[/tex]
Thus, the average rate of change of the function f(x) over the interval [tex][2, 6][/tex] is 2.

(-5,-3) (5,-4) slope =
Answers
Answer:
Your slope would be -1/10
Step-by-step explanation:
To find the slope from two points, you would use the formula y2-y1/x2-x1
In this case, the equation would look like -4-(-3)/5-(-5)
-4 - (-3) = -1
5 - (-5) = 10
-1/10 = -1/10

....
Simplify
5z+9-8z-7: -3z+2
Answer:
-3z +2
Step-by-step explanation:
A expression in terms of z is given to us and we need to simplify out the given expression . The give an expression to us is ,
[tex]\implies (5z + 9 ) - ( 8z + 7 )[/tex]

Answer: x^4 + x^3 + 7x^2 + 49x - 30
Step-by-step explanation:
first, we use the distributive property.
x^2 x (x^2 - 2x + 15) + 3x x (x^2 -2x + 15) - 2(x^2 - 2x + 15)
then, we remove the parenthesis.
x^4 - 2x^3 + 15x^2 + 3x^3 - 6x^2 + 45x - 2x^2 + 4x - 30
then, we collect like terms.

Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?
Answers
Answer:
2x - 5 = (1/2)
4x - 10 [multiply by 2]
x - 10 = -13 [subtract 3x from both sides]
x = -3 [add 10 to both sides]
Step-by-step explanation:
The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"
What is algebra?Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.
When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."
"Twice the value of a number" is simply 2x.
"Five less" is simply -5, so for the first part we have (2x-5)
Examine the second section next. "Three times four times more than one half the number."
"Three times the quantity" simply indicates "three times something."
4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."
So the second part is simply 3(4+x/2).
Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.
2x-5 = 12 + (3/2)x
2x-(3/2)x = 17
x/2 = 17
x = 34
Therefore, the required number would be 34.

Step-by-step explanation:
m∠5 +m∠6 = 180° ( the angles form a line)
m∠2 + m∠3 = m∠6 ( exterior angle is the sum of 2 not adjacent angles)
