Answer:

Step-by-step explanation:

you can't really solve for x because there is no equal sign to determine how much x needs to be in order to get the sum.

The average rate of change of the function over the interval is -9.25

The given parameters are

h(x) = x^2 - 5x + 11

−8 ≤ x ≤ 4

Calculate h(4) and h(-8)

So, we have

h(4) = (4)^2 - 5(4) + 11 = 7

h(-8) = (-8)^2 - 5(-8) + 11 = 115

The average rate of change of the function over the interval is then calculated as

Rate = [h(4) - h(-8)]/[4 - -8]

This gives

Rate = [7 - 118/[12]

Evaluate

Rate = -9.25

Hence, the average rate of change of the function over the interval is -9.25

Step-by-step explanation:

25. 5 < x < 7

The equation of the polynomial with the given roots of 2, -2, and 4 is x³ - 4x² - 4x + 16 = 0.

Roots are the points where the graph intercepts with the x-axis ( y = 0 ).

Given the roots in the question;

x = 2, -2, 3

Now, the root of x = 2 was found solving for x when x - (2) = y but y = 0.

Hence, (x - 2) is a factor.

Next, the root of x = -2 was found solving for x when x - (-2) = y but y = 0.

Hence, (x + 2) is a factor

And the root of x = 4 was found solving for x when x - (4) = y but y = 0.

Hence, (x + 2) is a factor

Now, combine all the factors into a single equation and simplify.

( x-2 )( x + 2 )( x - 4 ) = y

( x² + 2x - 2x - 4 )( x - 4) = 0

( x² - 4 )( x - 4) = 0

x( x² - 4 ) -4( x² - 4 ) = 0

x³ - 4x - 4x² + 16 = 0

x³ - 4x² - 4x + 16 = 0

x³ - 4x² - 4x + 16 = 0

Therefore, the equation of the polynomial with the given roots of 2, -2, and 4 is x³ - 4x² - 4x + 16 = 0.

Explanation:

Recall that the opposite sides of any rectangle are the same length.

This means the top and bottom sides are the same length

top = bottom

2x+17 = 6x+9

2x-6x = 9-17

-4x = -8

x = -8/(-4)

x = 2

Then we can find each side:

We get the same length for top and bottom (21), which confirms the correct x value.

This is a 7 by 21 rectangle with area = length*width = 7*21 = 147 square units.

Due to length restrictions, we kindly invite to check the explanation of this question for further details on equations.

In this problem we find equations that have got to be cleared with respect to a given variable, this can be done by taking advantage of algebra properties:

14) b / c = a → c = b / a

15) k = a - y → y = a - k

16) d · f · g = h → f = h / (d · g)

17) 2 · x + 3 · y = 12 → 3 · y = 12 - 2 · x → y = 4 - (2 / 3) · x

18) 2 · n = 4 · x + 2 · y → n = 2 · x + y

19) a · b · c = 1 / 2 → b = 1 / (2 · a · c)

20) y = 3 / (5 · u) + 5 → y - 5 = 3 / (5 · u) → 5 · u = 3 / (y - 5) → 3 / [5 · (y - 5)]

21) 8 · (x - a) = 2 · (2 · a - x) → 8 · x - 8 · a = 4 · a - 2 · x → 10 · x = 12 · a → x = (6 / 5) · a

22) 12 · (m + 3 · x) = 18 · (x - 3 · m) → 12 · m + 36 · x = 18 · x - 54 · m → 66 · m = - 18 · x → m = - (3 / 11) · x

23) V = (π / 3) · r² · h → h = [3 · V / (π · r²)]

24) V = (π / 3) · r² · (h - 1) → h - 1 = [3 · V / (π · r²)] → h = 1 + [3 · V / (π · r²)]

25) y · (a - b) = c · (y + a) → a · y - b · y = c · y + a · c → (a - b - c) · y = a · c → y = (a · c) / (a - b - c)

26) x = [3 · (y - b)] / m → (m · x) / 3 = y - b → y = b + (m · x) / 3

27) F = - (G · m) / r² → G = - (F · r²) / m

Answer: 7x -4

Step-by-step explanation:

The angles EFG and GFH are 71 and 109 degrees

The given parameters are:

EFG =2n + 25

GFH = 4n + 17

Linear pair angles are supplementary angles

So,we have

2n + 25 +4n + 17 = 180

Evaluate the like terms

6n= 138

Divide by 6

n = 23

Substitute n = 23 in EFG =2n + 25 and GFH = 4n + 17

EFG = 2 * 23 + 25 =71

GFH = 4 * 23 + 17 = 109

Hence, the angles EFG and GFH are 71 and 109 degrees

Step-by-step explanation:

The coordinate of point X such that the ratio of MX to XJ is 3:1 is 12

The coordinates are given as:

M = 2

J = 18

The ratio is given as:

Ratio = 3 : 1

The location of the point X is then calculated as:

X = Ratio * (J - M)

This gives

X = 3/(3 + 1) * (18 - 2)

Evaluate

X = 3/4* 16

This gives

X = 12

Hence, the coordinate of point X such that the ratio of MX to XJ is 3:1 is 12

Step-by-step explanation:

First, we know the total number of students: 135

Then we can see that 22+31+28 students like two flavours: 81

Then we can see how many students like all three flavours: 15

Because the students who like two flavours are counted twice, we need to subtract them once.

Because the students who like three flavours are counted three times, we need to subtract them twice.

So we get 135-81-15*2

135-81-30

24

24 students do not like any of the given flavours

if this was helpful pls give me brainliest <3

Answer: 24 students dislike any of the flavors

Step-by-step explanation:

Soo since you have the diagram without any error it the other question soo at the start of the question they have told that in total there are 135 students.

so at the all the number of students with the different types of flavors then you will get the total amount of students who like 2 kinds of flavors and all three flavors.

31+22+28+15+15= 111 students  (since the students who like three flavors are counted three times, we need to subtract them twice, I add it here to make it easier *15+15*)

so next you should subtract that amount from the total amount of students  who likes multiple flavors in order to get the number of students who dislikes and of the flavors.

135-111= 24 students dislike any of the flavors

Based on the given parameters, the numerical length of PT is 9 units

The given parameters are:

P is a point on ST such that P is between S and T.

SP = x + 3,

PT = 2x - 1

ST = 17

The statement "P is a point on ST such that P is between S and T" implies that

ST = SP + PT

Substitute the known values in the above equation

17 = x + 3 + 2x - 1

Evaluate the like terms

17 = 3x + 2

Add 2 to both sides of the equation

3x = 15

Divide both sides of the equation by 3

So, we have

x = 5

Substitute x = 5 in PT = 2x - 1

So, we have

PT = 2 x 5 - 1

Evaluate

PT = 9

Hence, the numerical length of PT is 9 units
