The function y=f(x) is graphed below. What is the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1?
Answer:
The average rate of change of the function is: 0
Step-by-step explanation:
The function y = f(x) is graphed below.
From the graph it is clear that:
at x = -8, the value of f(-8) = -10
at x = -1, the value of f(-1) = -10
We have to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.
so
at x₁ = -8, f(x₁) = f(-8) = -10
at x₂ = -1, f(x₂) = f(-1) = -10
Using the formula to determine the average rate of change of the function f(x) on the interval -8 ≤ x ≤ -1.
Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]
= [f(-1) - f(-8) ] / [-1-(-8)]
= [-10 - (-10)] / [-1+8]
= [-10 + 10] / 7
= 0 / 7
= 0
Therefore, the average rate of change of the function is: 0

7 blue socks and 6, 5, 8 of non-blue socks. If you add the numbers of non-blue socks you get 19. Blue socks to non-blue would be 7:19
Answer:
The ratio is 7 to 19 or 7:19
Step-by-step explanation:
Since there are 7 blue socks and other colors are not blue we add the number of other colors. So basically 8+5+6= 19 and then 7 blue socks :)
3. Triangle ABC has angle measures as noted below. Please note this triangle is not drawn to scale, and the longest leg of the figure may not be the longest leg of the actual triangle.
You will need to use the expressions for the angles given below.
A) 2(x + 15) B) 3x+10 C) 5x
(a) Identify the angle relationship and setup your equation with the given expressions.
(b) What is the value of x? Show your work.
(c) What is the measure of angle A, B, & C? Show your work and make sure to identify which is which.
Answer:
I only know B and C
Step-by-step explanation:
Part B)
2 (x+15) + 3x + 10+ 5x = 180 2x + 30 + 3x + 10 +5x = 180 10 +40 = 180
- 40 -40 10x divided by 10 = 140 divided by 10 x= 14
Part C)
A = 2 (x + 15) = 2 (14 + 15) = 2 * 29 = 58 degrees
< B = 3 x + 10 = 3 * 14 + 10 = 52 degrees
< C = 5 x = 5 * 14 = 70 degrees
Solve using the order of operations. (9+9+72)-4+9
PLZ ANSWER PLZ HURRY
Answer:
95
Step-by-step explanation:
The order of operations is PEMDAS
Equations in PARENTHESES come first
Numbers with EXPONENTS come second
MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation
ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)
So we do (9+9+72) first
So that equals 90
And then we subtract 4 from 90
90 - 4 = 86
Then we add 9 to 86
86 + 9 = 95
Answer: 72 is the answer

Answer:
n/3
Step-by-step explanation:
n×by n is=n square.
n/3
Probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].
What is probability?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Given
Probability that Sara wins a raffle is given by the expression
P(win) = [tex]\frac{n}{n+3}[/tex]
Probability that Sara does not wins a raffle is given by
P(does not win) = 1 - [tex]\frac{n}{n+3}[/tex]
= [tex]\frac{n+3}{n+3} -\frac{n}{n+3}[/tex]
= [tex]\frac{n+3-n}{n+3}[/tex]
= [tex]\frac{3}{n+3}[/tex]
Thus, probability that Sara does not wins a raffle is [tex]\frac{3}{n+3}[/tex].

Solve the inequality for x.
- 4x + 16 > -64
A)
X> 12
B)
X > 20
x < 12
D
x < 20
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
2/3(x+6)=-8 whats the value of x?
Answer:
x=-18
Step-by-step explanation:
Answer:
The answer is -18
Step-by-step explanation:
STEP 1:
[tex]3 \times \frac{2}{3} (x + 6) = 3( - 8)[/tex]
2(x+6) = -24
______________________________________
STEP 2:
Divide both sides by 2:

________________________________
STEP 3:
Simplify:
[tex]x + 6 = - 12[/tex]
Subtract 6 from both sides:
[tex]x + 6 - 6 = - 12 - 6[/tex]
________________________________
STEP 4:
[tex]x = - 18[/tex]
Therefore, your answer is -18.
