Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Step-by-step explanation:
Given
The function is [tex]f(x)=x+4[/tex]
for [tex]x_2>x_1[/tex], we will check the values of [tex]f(x_1)[/tex] and [tex]f(x_2)[/tex]
Take 3 and 4
[tex]f(4)=4+4\\f(4)=8[/tex]
Similarly,
[tex]f(3)=3+4\\f(3)=7[/tex]
Thus, [tex]f(4)>f(3)[/tex]
Also, [tex]f'(x)[/tex] is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.

WILL MARK BRAINLIEST WHOEVER CAN HELP WITH THIS :DDD!
Answer:
8) 1/4
9) 1/4
10) 1/8
11) 3/8
Here are the correct answers :)
Answer:
P(2): 1/4
P(1): 1/4
P(4): 1/8
P(3 or 5): 3/8
Step-by-step explanation:
The areas marked 1, 2, and 3 each take up 1/4 of the box. This means that the probability that you will spin the arrow and land in any of those spaces is 1/4 each.
Areas 4 and 5 are HALF the size of areas 1, 2, and 3. This means that areas 4 and 5 are half of 1/4. Half of 1/4 is 1/8.
The word "or" means that you ADD whatever two probabilities they are asking for. In this case, you add areas 3 and 5. So, add 1/4 + 1/8 = 3/8.
(an easy way to add 1/4 to 1/8 is to change 1/4 to 2/8. Then you can add the two areas easily)
If y=3x and 2x−4y=3 , then x=
Answer:
x = -3/10
Step-by-step explanation:
Solve for x by substituting y = 3x into the other equation:
2x - 4y = 3
2x - 4(3x) = 3
Simplify and solve for x:
2x - 12x = 3
-10x = 3
x = -3/10
So, x = -3/10
Answer:
[tex]x=-\frac{3}{10}[/tex]
Step-by-step explanation:
2x - 4y = 3
y = 3x
2x - 4(y = 3x) = 3
2x - 4(3x = 3)
2x - 12x = 3
- 10x = 3
- 10x ÷ - 10 = 3 ÷ - 10
[tex]x=-\frac{3}{10}[/tex]
HYRIGH fararefant et fanter i In a class of 25 student,
17 like volleyball, 15 like basketball and 10 like both games.
Illustrate it with a Venn-diagram and find the number of
students who don't like any of the games. (Ans: 3]
Given:
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
To find:
The students who don't like any of the games.
Solution:
We have,
Total students in a class = 25
Students who like volleyball = 17
Students who like basketball = 15
Students who like both = 10
Now,
Students who like only volleyball = 17-10
= 7
Students who like only basketball = 15-10
= 5
Students who don't like any of the games is the difference of total number of students and number of students who like at least one game.
Students who don't like any of the games = 25 - (7+5+10)
= 25 - 22
= 3
Therefore, 3 students don't like any of the games.

Answer:
x = 9
Step-by-step explanation:
Corresponding sides are in proportion, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{3}{8}[/tex] ( cross- multiply )
8x = 72 ( divide both sides by 8 )
x = 9
A game spinner is divided into 5 congruent sections and labeled, as shown below.
The arrow will be spun 100 times. Which of the following is most likely the number of times the arrow will stop on the section labeled “lose a turn”?
Answer:
G. 20
Step-by-step explanation:
The spinner has a total of 5 equally sized sections. This means that each possible outcome has an equal probability of 1/5 (0.20 in decimal form) that the spinner lands on it. Therefore, to calculate the number of times that the spinner would most likely land on "lose a turn", we need to multiply the probability that we just mentioned by the number of times the spinner will be spun...
0.20 * 100 = 20 times
Finally, we can see that the spinner will most likely land on "lose a turn" 20 times in 100 spins.
Answer:
20
Step-by-step explanation:
Which of these describe a scenario in which the given quantity changes at a constant rate with respect to time? Select
all that apply.
A. A town's population increases by 218 people every 2 years.
B. There are 1,240 people exiting a football stadium every 10 minutes.
C. A country's population increases by 1.65% each month.
D. The number of registered voters in a county decreases by 0.25% each year.
Answer: A,B
Step-by-step explanation: the numbers constantly add up only by 218 or 1240 , C and D would not be correct because the rate of change increases as will with the total sum after each period of time
also tiny hint, if you were to draw an X,Y axis graph, A and B would be a straight line while C and D are curved up-wards

Look at the picture A cube has a volume of 27 cubic units. A square has an area of 16 square units. Which of the following statements is true?
side length of square =4
side length of cube=3
hence the correct statement is,
the side length of the cube is less than the side length of the square
Please someone teach me this don't just solve it I wanna learn how to do it thank you!
Answer:
284 cubic cm
Step-by-step explanation:
Volume = length x width X height
Volume of first shape: 11 x 4 x 6 = 264 cubic cm
Volume of second shape: 5 x 2 x 2 = 20 cubic cm
Vol of 1st + vol of 2nd = 264 + 20 = 284 cubic cm
Answer:
284 cm^3.
Step-by-step explanation:
These are 2 prisms.
Their volume = length*width*height.
Volume of the large prism
= 4 * 6 * 11
= 264 cm^3
Volume of the small prism
= 2 * 2* 5
= 20 cm^3
So the volume of the whole solid = 264 + 20
= 284 cm^3.

f(x) = x2. What is g(x)?
g(x)
5
-(1,4)
f(x)
X
-5
5
-5
Answer:
B. g(x) = 4x²Step-by-step explanation:
f(x)= x²
the shape of f (x ) and g( x ) is same.
and those graphs lower point is ( 0 , 0 )
therefore,
will, g(x) = kx² (k ∈ real numbers)
the g(x) graph goin through the point ( 1 , 4 )
therefore,
4 = k × 1²
k = 4
∴ g(x) = 4x²

the system of equatuions 2y = 14 - 2x and y= -x+7 is graphed. what is the solution to the system of equations
Answer:
the solution is the whole line y = -x + 7
Step-by-step explanation:
both equations are identical
2y = 14 - 2x
=> y = 7 - x
which is exactly the same information as y=-x+7
so, there is no single crossing point. they are exactly covering each other. what "remains" is simply the whole line.

A and i'm pretty sure
Step-by-step explanation:
:D
Answer:
I think it's B.
Step-by-step explanation:
-5x + 1 ≥ -29
-5x + 1 - 1 ≥ -29 - 1
-5x ≥ -30
-5x / -5 ≥ -30 / -5
x ≥ 6
You flip the inequality sign because you divided both sides by a negative number.
x ≤ 6
