Answer:

3*x

Step-by-step explanation:

Note that 3*x + 9 = 3*x if you choose to put the expression 3*x on the right side of the expression.

To solve this equation, you subtract 3 * x on both sides of the equation, obtaining:

3*x+9-3*x=3*x-3*x

9=0

You get 9 = 0. This expression cannot be true regardless of the value taken by x. You can tell then that in this case the equation has no solution.

Answer:

225 feet.

Step-by-step explanation:

15 X 15

Answer:

The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Step-by-step explanation:

I assume an x is missing, and the function is h(x) = -3x^2 + 30x + 225

You want to know the number of days in which the function value is zero.

-3x^2 + 30x + 225 = 0

Divide both sides by -3.

x^2 - 10x - 75 = 0

(x - 15)(x + 5) = 0

x - 15 = 0 or x + 5 = 0

x = 15 or x = -5

We discard the negative solution.

Answer: The equation is -3x^2 + 30x + 225 = 0, and the number of days is 15.

Answer:

h(x) = -3 (x + 5) (x - 15)

Step-by-step explanation:

h(x) = -3x^2 + 30 + 225

      = -3(x^2 - 10x - 75)

      = -3(x + 5)(x - 15)

      x = -5    x = 15

If we have two functions [tex]f \ and \ g[/tex] such that [tex]f(g(x))=x[/tex] for every [tex]x[/tex] in the domain of [tex]g[/tex], and [tex]g(f(x))=x[/tex] for every for every [tex]x[/tex]in  the domain of  [tex]f[/tex]. If we prove this, then [tex]g[/tex] is the invers function of [tex]f[/tex] and denoted by [tex]f^{-1}[/tex]

1. We need to prove whether [tex]f(g(x))=x[/tex]. So:

[tex]f(x)=\frac{4}{5}x+1 \\ \\ g(x)=\frac{5x-5}{4} \\ \\ So: \\ \\ f(g(x))=\frac{4}{5}\left(\frac{5x-5}{4})+1 \therefore f(g(x))=\frac{4}{5}\left(\frac{5x-5}{4})+1[/tex]

[tex]\therefore f(g(x))=x-1+1 \\ \\ \boxed{f(g(x))=x}[/tex]

2. We need to prove whether [tex]g(f(x))=x[/tex]. So:

[tex]g(f(x))=\frac{5(\frac{4x}{5}+1)-5}{4} \\ \\ \\ g(f(x))=\frac{4x+5-5}{4} \\ \\ \\ g(f(x))=\frac{4x}{4} \\ \\ \\ g(f(x))=x[/tex]

Since [tex]f(g(x))=g(f(x))=x[/tex], then:

[tex]f(x) \ and \ g(x)[/tex] are inverses to each other.

I would say 45 degrees

The whole square is 360 degrees because each corner is a 90 degree angle

Which means each triangle section would be 90 degrees but angle 2 is cut in half, so half of 90 is 45

A Monte Carlo simulation can be used to answer questions about the type of lunch students will choose.

A simulation that could be used to answer questions about the type of lunch students will choose is a Monte Carlo simulation.

In this simulation, the probability of a student choosing a salad over a grilled chicken sandwich is represented by a random number generator.

Each time the simulation is run, a random number between 0 and 1 is generated, and if the number is less than or equal to 0.33, it is considered a salad choice. This process is repeated multiple times to generate a distribution of lunch choices.

By analyzing the distribution, you can estimate the likelihood of students choosing a salad over a grilled chicken sandwich.

Final answer:

A simulation to model the 33% chance of students choosing a salad over a grilled chicken sandwich could involve a random generator where the number 1 (out of 1 to 3) represents the choice of a salad, simulating the probability accurately.

Explanation:

To simulate the situation where there is a 33% chance that a student will choose a salad over a grilled chicken sandwich for lunch, you could use a simple random process to model this probability. You might simulate the choice by using a random number generator set to generate numbers from 1 to 3, where one of the numbers (say 1) represents choosing a salad, and the other two numbers (2 and 3) represent choosing a grilled chicken sandwich. Every time the number 1 comes up, it would count as a 'success', representing a student choosing a salad. You could run this simulation a large number of times to answer questions about the likelihood of various outcomes related to the students' lunch choices.

Final answer:

To solve the equation 3w - 4z = 8 for w, add 4z to both sides and then divide by 3, resulting in the expression w = (4z + 8) / 3.

Explanation:

The student's equation, 3w - 4z = 8, involves algebraic manipulation to solve for the variable w. To isolate w, we rearrange the equation to get w by itself on one side of the equation:

Add 4z to both sides to get: 3w = 4z + 8

Divide both sides by 3 to solve for w: w = (4z + 8) / 3

Now we have w expressed in terms of z. This is the solution for w assuming you have a specific value for z you can substitute into this expression.

Final answer:

To find w, isolate it by adding 4z to both sides and then dividing by 3, resulting in w = (8 + 4z) / 3.

Explanation:

To solve for w in the equation 3w - 4z = 8, you would isolate w on one side of the equation. First, add 4z to both sides of the equation so that you have 3w = 8 + 4z. Then, divide both sides by 3 to get w by itself. The final equation representing w would be w = (8 + 4z) / 3. This doesn't directly correspond to the provided physics equations; however, we can apply a similar method of isolating the unknown in those as well.

Answer:

d.  4, 8, 16, 32

Step-by-step explanation:

We'll use the formula  f(x) = 2x  for each iteration.  The output of the first iteration will be come the input of the second iteration, and so on.

So, we start with x0 = 2 and we plug that into the base equation:

x0 = 2 ==> f(x) = 2(2) = 4

x1 = 4 ==> f(x) = 2(4) = 8

x2 = 8 ==> f(x) = 2(2) = 16

x3 = 16 ==> f(x) = 2(2) = 32

x4 = 32 ==> f(x) = 2(2) = 64

Answer:

The simple interest is 3.80% per year.

Step-by-step explanation:

We are presented with a simple interest problem and the following information has been availed;

Accumulated amount = 5503.51

Time = 19 years

Principal = 3196

The first step is to determine the total interest earned over the entire time period;

Interest = Amount - Principal

             = 5503.51 - 3196

             = 2307.51

The simple interest formula states the total interest earned is equal to the product of the principal, the interest rate and the time;

[tex]I=\frac{P*R*T}{100}[/tex]

Making R the subject of the formula yields;

[tex]R=\frac{100*I}{P*T}[/tex]

Substituting the values we have and simplifying;

[tex]R=\frac{100*2307.51}{3196*19}=3.80[/tex]

The simple interest is thus 3.80% per year.

Answer:

[tex]x=\frac{32}{3}, y=\frac{2}{3}[/tex]

Step-by-step explanation:

We can multiply the second equation by 2 to eliminate.

Let's eliminate.

[tex]2x-5y=18 \\ -2x+2y=-20 \\ -3y=-2 \\ y=\frac{2}{3}[/tex]

Now we can substitute back into the equation to find the value of [tex]x[/tex].

[tex]\frac{2}{3}-x=-10 \\ \\ \frac{2}{3}-x=-\frac{30}{3} \\ \\ -x=-\frac{32}{3} \\ \\ x=\frac{32}{3}[/tex]

EXPLANATION

The linear function includes the ordered pairs (2,5), (6,7) and (k,11).

The slope of this line is the same for any two given points:

[tex] \frac{7 - 5}{6 - 2} = \frac{11 - 7}{k - 6} [/tex]

[tex]\frac{2}{4} = \frac{4}{k - 6} [/tex]

Cross multiply,.

2(k-6)=4×4

2(k-6)=16

Divide both sides by 2

k-6=8

k=8+6

k=14

Answer:

Option D will be the answer.

Step-by-step explanation:

y intercept form of a line is represented by y = mx + c

Where m = slope of the line and c = y- intercept of the line.

A line passing through two points (2, 5) and ( 6, 7) has the slope

m = [tex]\frac{y-y'}{x-x'}[/tex]

   = [tex]\frac{7-5}{6-2}[/tex]

  = [tex]\frac{2}{4}[/tex]

  = [tex]\frac{1}{2}[/tex]

Equation will be y = [tex]\frac{x}{2}+c[/tex]

This line passes through (2, 5)

5 = [tex]\frac{1}{2}\times 2+c[/tex]

c = 5 - 1

c = 4

And the equation will be y = [tex]\frac{1}{2}x+4[/tex]

Since a point (k 11) passes through the line then we will plug in these values in the equation to find the value of k.

11 = [tex]\frac{1}{2}\times k+4[/tex]

11 - 4 = [tex]\frac{k}{2}[/tex]

7 = [tex]\frac{k}{2}[/tex]

k = 2×7

  = 14

Option D will be the answer.

Answer:

Length: 28 ft  Width: 12 ft

Step-by-step explanation:

So to solve this, we know that perimeter means the sum of all the lengths added together. And we can start by dividing 80 by 4.

80 ÷ 4 = 20

And now, the width must be eight feet less than the length, meaning we just subtract eight from the width, and add eight to the length.

20 - 8 = 12

20 + 8 = 28

L = 28

W = 12

And now we can double check:

12+ 28 + 12 + 28 = 80

AREA = 2770 if you're shortening.

For this case we assume that the moon is spherical. For definition, the surface area of a sphere is given by:

[tex]S = 4 \pi*r ^ 2[/tex]

Where:

A: It is the radius of the sphere

ANSWER

The system has one solution.

EXPLANATION

The given system is

1st: 5x-3y=10

2nd: 10x+6y=20

Make y the subject in the first equation to get:

[tex]y = \frac{5}{3} x + \frac{10}{3} [/tex]

Solve for y in the second equationquation to get;

[tex]y = - \frac{5}{3} x + \frac{10}{3} [/tex]

The slope of the two equations are not the same.

The two lines will intersect at exactly one point.

.The system has one solution.

Answer:

One solution

Step-by-step explanation:

We are given the following system of equations and we are to tell if the system has one solution, infinite solution, many solutions or no solutions:

[tex]5x-3y=10[/tex] --- (1)

[tex]10x+6y=20[/tex] --- (2)

If we take the common out from (2), we get:

[tex]2(5x+3y) = 20 [/tex]

[tex]5x+3y = 10 [/tex] --- (3)

So adding the two equations (1) and (3) gives 10x=20 ⇒ x=2.

Therefore, this system of equations has one solution.

Answer:

20.25π

Step-by-step explanation:

The circumference (C) of a circle is calculated using the formula

C = 2πr ← r is the radius

given C = 9π, then

2πr = 9π ( divide both sides by 2π )

r = [tex]\frac{9\pi }{2\pi }[/tex] ( cancel the π on numerator/denominator )

  = 4.5

The area (A) of a circle is calculated using the formula

A = πr² = π × 4.5² = 20.25π

Answer:

r = 6

Step-by-step explanation:

Given that p varies directly as r, then the equation relating them is

p = kr ← k is the constant of variation

To find k use the condition p = 4, r = 2

k = [tex]\frac{p}{r}[/tex] = [tex]\frac{4}{2}[/tex] = 2

p = 2r ← equation of variation

When p = 12

12 = 2r ( divide both sides by 2 )

hence r = 6

Answer:

If a car can go 200 miles in 6 hours at a constant rate, in 7 hours it will have gone 233.33 (0.33 repeating) miles.

Step-by-step explanation:

If a car can go 200 miles in 6 hours, then we know it can go about 33.33 miles per hour (found by dividing 200 by 6).

If the car is going at this constant rate we can then multiply 33.33 by 7, which would give us 233.33.

The car can go 233.33 miles in 7 hours

A comparison of two entities by dividing them is called Proportion and when two ratios are equated to one another , they are said to be in proportion.

It is given in the question that

a car can go 200 miles in 6 hours

Distance covered in 7 hours

In the given question the ratio of Distance covered and time is

200/6 = 100/3 = 100:3

Let the distance covered in 7 hours is x

therefore the ratio will be x : 7

These two ratios will be in proportion

100:3 = x: 7

100/3 = x / 7

x = 100 * 7 / 3

x = 700 / 3

x = 233.33 miles

Therefore The car can go 233.33 miles in 7 hours .

The next term would be -27

Lets pretend that all the negative signs went away, that way you have the data:

2, 5, 9, 14, 20

^^^In my opinion it just makes it easier because I don't like negative numbers. Keep in mind that the negatives are still there but I just made them "Invisible"

The pic below is how I found the pattern. If you can't tell by the picture from 2 to 5 it increases by 3. From 5 to 9 it increases by 4. From 9 to 14 it increases by 5. From 14 to 20 it increases by 6.

This means the pattern is to increase the number 1 more then the amount the previous number was increased (keep in mind this is the pattern for the positive version and therefore the original pattern would be decreasing (since the bigger a number that is negative is, the farther away it gets from zero, therefor getting smaller.) For the original version the rule would be: it would decrease the number 1 more then the amount the previous number was decreased) <<<Hope that makes sense

That means that 20 will be increased by 7 ( 6+ 1 = 7). Which equals 27. Make the negative sign visible again and your answer is -27.

Answer:

A) Quadratic

Step-by-step explanation: It has the U shape of a parabola which a quadratic equation has.

Answer:

The correct option is A.

Step-by-step explanation:

In a scatter plot the best fit curve in known as regression curve. Types of regression curves are

1. Linear regression line : If the best fit of a data is a straight line, then it is known as linear regression line.

2. Quadratic regression : If the best fit of a data is a U-shape curve, then it is known as quadratic regression.

3. Exponential regression : If the best fit of a data is an exponential curve, then it is known as exponential regression.

From the given graph it is clear that scatter data forms a U-shaped curve. Since the best fit of a data is a U-shape curve, therefore the quadratic regression model is best for the data.

Thus, option A is correct.
