PLZ HELP!!!Solve the equation, and enter the solutions from least to greatest. If there is only one solution, enter “n.a.” for the second solution.

Answer:

The graph in the attached figure

Step-by-step explanation:

Let

x -----> the number of solved puzzles

y -----> the number of solved riddles

we know that

[tex]2x+y \geq 4[/tex]

The solution of the inequality is the shaded area above the solid line [tex]2x+y=4[/tex]

The slope of the solid line is negative [tex]m=-2[/tex]

The y-intercept of the solid line is the point (0,4)

The x-intercept of the solid line is the point (2,0)

therefore

The graph in the attached figure

Answer:

The graph that representss this scenario is attached.

Explanation:

You can create the graph by determining the expression that shows the relationship between the variables and then drawing the graph in a coordinate system.

1. Determine the expression that relates the variables.

a) The name of the variables is given:

x: number of solved puzzles

y: number of solved riddles

b) Point rules:

Each solved puzzle is worth two points: 2x

Each solved riddle is worth 1 point: 1y = y

Sum of points: 2x + y

The video game requires at least 4 points to advance: this means that the number of points must grater than or equal to 4 ⇒ 2x + y ≥ 4 .

In conclusion, it has been determined that the expression that rules the system of points is the inequality 2x + y ≥ 4.

2) Building the graph

Solve algebraically for y: y ≥ 4 - 2x

You want to draw the border line of the function, that is y = 4 - 2x

You have a linear function, so you need only two points to draw it. It is generally easier to work with the intercepts.

x-intercept (y = 0) ⇒ 2x + 0 = 4 ⇒ 2x = 4 ⇒ x = 2 ⇒ point (2, 0)

y-intercept (x = 0) ⇒ 2(0) + y = 4 ⇒ y = 4 ⇒ point (0, 4).

In conclusion, you can use the points (2,0) and (0,4) to draw the line that is the border of your graph.

Addtional constrains: x and y cannot be negative, so add the constrains:

       x ≥ 0 and y ≥ 0

The set of solutions of y ≥ 4 - 2x is the same line y = 4 - 2x and the region over the line, so you have to shade that portion of the graph, but only in the first quadrant (since x and are greater than or equal to zero).

Answer:

Option C (d = 14n + 50).

Step-by-step explanation:

The observations for Year 1, 2, 3, and 4 are 64, 78, 92, and 106 respectively. It can be observed that the difference between second term and the first term is 78 - 64 = 14. This is also true for the third term and the second term. In fact, the difference between the terms is fixed. This means that the sequence is an arithmetic sequence, in which the difference between the terms is fixes for all the terms. The nth term in this case is defined as:

S = a + (n-1)*d; where S is the output at a given n, a is the first term, n is the position, and d is the common difference. In this question, S = ducks (d), a = 64, and d = 14. Therefore, plugging in the values in the above formula gives:

d = 64 + (n-1)*14.

d = 64 + 14n - 14.

d = 14n + 50.

Therefore, the model which best describes the amount of ducks that will be in the pond during the nth year is d = 14n + 50, i.e. Option C!!!

Answer: Third Option

[tex]a_n =14n+50[/tex]

Step-by-step explanation:

By subtracting consecutive terms from the number of ducks each year you will get a common difference of 144.

[tex]78-64 = 14\\92-78 = 14\\106-92 = 14[/tex]

This means that the data can be modeled by the equation of an arithmetic sequence

The arithmetic sequences have the following form:

[tex]a_n = a_1 + d(n-1)[/tex]

Where [tex]a_1[/tex] is the first term and d is the common difference between the consecutive terms.

So :

[tex]a_1 = 64[/tex]

[tex]d = 14[/tex]

Then the equation is:

[tex]a_n = 64 + 14(n-1)[/tex]

[tex]a_n = 64 + 14n-14[/tex]

[tex]a_n =14n+50[/tex]

Answer:

The monthly compounded interest rate of 0.14% of Unity Bank is a better plan.

Step-by-step explanation:

Step 1 : Write the formula for calculating a monthly compound interest rate and for calculating an annually compounded interest rate.

Monthly compound interest rate = P(1+r/n)^nxt

n=12 (number of months in a year)

t=1 (number of years)

Annually compound interest rate = P(1+r/n)^nxt

n=1 (because it is for 1 year only)

t=1 (number of years=1)

Step 2 : Lets assume that P is $100 in both banks and time is 1 year.

Step 3 : Lets substitute the values to find out which one is better.

Monthly compound interest rate = P(1+r/n)^nxt

Monthly compound interest rate = 100(1+0.14/12)^12x1

Monthly compound interest rate = 114.93

114.93 - 100 = $14.93 per month

14.93 x 12 = $179.16 for 12 months or 1 year

Annually compound interest rate = P(1+r/n)^nxt

Annually compound interest rate = 100(1+1.6/1)^1x1

Annually compound interest rate = 260

260-100 = $160 for 1 year

Therefore, the monthly compounded interest rate of 0.14% of Unity Bank is a better plan.

!!

Answer:

The Unity Bank is offering a good plan.

Step-by-step explanation:

Unity Bank offers a monthly compounded interest rate of 0.14%

So, yearly rate will be = [tex]0.14\times12=1.68[/tex]% or 0.0168

Sunrise Banking offers 1.6% or 0.016 interest compounded annually.

Lets check an example with these two rates.

The compound interest formula is = [tex]A=P(1+r/n)^{nt}[/tex]

Lets take P = $1000 and t = 1 year

Case 1: when r = 1.68% and n = 12

Putting the values in formula we get

A = [tex]1000(1+0.0168/12)^{12}[/tex]

= [tex]1000(1.0014)^{12}[/tex]

A = $1016.92

Case 2: when r = 1.6% and n = 1

Putting the values in formula we get

A = [tex]1000(1+0.016/1)^{1}[/tex]

= [tex]1000(1.016)^{1}[/tex]

A = $1016.00

So, we can see that the first case gives more return than second one.

Therefore, the Unity Bank is offering a good plan.

Answer:

Step-by-step explanation:

The two represents 2000

The one represents 10

The fraction you want is 10/2000 = 1/200 or 0.005

The value represented by the digit 1 in the number 2010 is 1/200 of the value represented by the digit 2. This is determined by comparing their place values, with 1 in the tens place and 2 in the thousands place.

To determine the value represented by the digit 1 in the number 2010, we need to understand place value.

→ The digit 1 is in the tens place, so its value is 10 (1 × 10).

→ The digit 2 is in the thousands place, so its value is 2000 (2 × 1000).

The fraction of the value represented by the digit 1 to the value represented by the digit 2 is calculated as follows:

→ Fraction = Value of digit 1 / Value of digit 2

                = 10 / 2000

                = 1/200

Therefore, the value represented by the digit 1 is 1/200 of the value represented by the digit 2 in the number 2010.

Answer:

So the factors of the given are:

(x-4) and (x-9).

The factored form of the given expression is (x-4)(x-9).

Step-by-step explanation:

To factore the given quadratic with leading coefficient one, you must find two numbers that add to be and multiply to be c.

a=1

b=-13

c=36

So we need two numbers that multiply to be 36 and add to be -13.

These numbers are -4 and -9 since

(-4)(-9)=36 and -4+-9=-13.

So the factors of the given are:

(x-4) and (x-9).

The factored form of the given expression is (x-4)(x-9).

Answer:

They are 2 and 3.

Step-by-step explanation:

2 * 3 = 6

The answer is:

Range: All the real numbers or (-∞,+∞)

To solve the problem, we need to rewrite the variable "x" as "y" and the variable "y" as "x", and then, isolate "y". Then, we need to look if there is any restriction to the resulting value of "y".

We are given the function:

[tex]y=log_8(x)[/tex]

Now, rewriting we have:

[tex]x=log_8(y)[/tex]

Then, isolating we have:

[tex]8^{x} =8^{(log_8(y))}\\\\8^{x}=y[/tex]

Therefore, we can see that the resultant function is a quadratic or polynomial function, we need to remember that there is no restriction for this type of functions, it means that the range of the function is equal to the Real numbers where the values of  "x" exist.

Hence, the answer is:

Range: All the real numbers or (-∞,+∞)

Answer:

-1/100

Step-by-step explanation:

10^(-2) becomes 1/100.

-(10)^(-2) is -1/100.

To find the cost of 4 ounces of pecans, we set up a proportion comparing the cost to weight, resulting in $2.25 after rounding to the nearest cent.

To determine the cost of 4 ounces of pecans when a one-pound (16 ounces) canister costs $8.99, we set up a proportion where the cost is directly proportional to the weight.

The proportion is $8.99/16 ounces = $X/4 ounces, where X represents the cost of 4 ounces of pecans.

Multiplying both sides by 4 to solve for X gives us $X = (4 ounces × $8.99) / 16 ounces.

Simplifying this, we find that $X = $2.2475, which, when rounded to the nearest cent, gives us an answer of $2.25.

Step-by-step explanation:

Answer:

The slope of given line = -3/2

Step-by-step explanation:

Points to remember

slope of the line with end points (x1, y1) and (x2, y2) is given by,

Slope = (y2 - y1)/(x2 - x1)

To find the slope of the line

Here (x1, y1) = (-7, 3) and (x2, y2) = (1, -9)

Slope = (y2 - y1)/(x2 - x1)

 = (-9 - 3)/(1 - -7)

 = (-12)/8

 = -3/2

Therefore the slope of given line = -3/2

Answer:

62 DEGREES

Step-by-step explanation:

TWO ANGLES=2A

LARGEST ANGLE=A+3

2A+A+3=180

3A=180-3=177

A=177/3=59

LARGEST ANGLE=59+3=62

Answer:

The Largest Angle angle has a measure of 62 degrees.

Step-by-step explanation:

In triangle ABC, angle ABC equals to angle ACB.

and BAC is the largest angle.

Let angle measure of ABC and ACB angles be "x" degree.

then, measure of third angle i.e BAC will be "x + 3" degrees.

Since sum of all angles of any triangle is 180 degree.

so,  first angle + second angle + third angle = 180

       x  + x + (x + 3) = 180

        3x  = 180 - 3

         3x = 177

          x = 59 degrees

So, First angle = 59 degree

     Second angle = 59 degree

     Third Angle = 62 degree.

The Largest Angle angle has a measure of 62 degrees.

m - slope

b - y-intercept → (0, b)

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

From the graph we have the points:

(0, 3) - y-intercept → b = 3 (for both lines)

Part 3) [tex]A=28.9\°[/tex]

Part 4) [tex]C=90\°[/tex]

Step-by-step explanation:

step 1

Find the length side c

Applying the Pythagoras Theorem

[tex]c^{2}=a^{2}+b^{2}[/tex]

substitute the given values

[tex]c^{2}=10.6^{2}+19.2^{2}[/tex]

[tex]c^{2}=481[/tex]

[tex]c=21.9\ units[/tex]

step 2

Fin the measure of angle B

we know that

In the right triangle

[tex]tan(B)=b/a[/tex]

substitute the given values

[tex]tan(B)=19.2/10.6[/tex]

[tex]B=arctan(19.2/10.6)=61.1\°[/tex]

step 3

Find the measure of angle A

we know that

The measure of interior angles in a triangle must be equal to 180 degrees

so

∠A+∠B+∠C=180°

Remember that in a right triangle the measure of angle C is 90 degrees

we have

[tex]B=61.1\°[/tex]

[tex]C=90\°[/tex]

substitute

[tex]A+61.1\°+90\°=180\°[/tex]

[tex]A=28.9\°[/tex]

Answer:

2(x-2y)/(4x-y)  =  dy/dx

Step-by-step explanation:

2x^2+y^2=8xy

Take the derivative of each term, remembering that we take the 8xy as derivative by parts)

2 * 2x dx +  *2y dy = 8 ( x dy + dx *y)

4x dx +2y dy = 8x dy + 8y dx

Subtract 2y dy from each side

4x dx +2y dy -4y dy = 8x dy - 2y dy + 8y dx

4x dx  = 8x dy - 2y dy + 8y dx

Subtract 8y dx from each side

4x dx -8y dx  = 8x dy - 2y dy + 8y dx-8y dx

4x dx -8y dx  = 8x dy - 2y dy

(4x-8y) dx = (8x-2y) dy

Factor out a 4 from the left side and a 2 from the right side

4(x-2y) dx = 2( 4x-y) dy

Cancel a 2

2(x-2y) dx = ( 4x-y) dy

Divide each side by (4x-y)

2(x-2y)/(4x-y) dx = ( 4x-y)/(4x-y) dy

2(x-2y)/(4x-y) dx =  dy

Divide by dx

2(x-2y)/(4x-y) dx/dx =  dy/dx

2(x-2y)/(4x-y)  =  dy/dx

Hello There!

X = 6

First, we would add 5 to both sides so adding 5 to -5 is 0 and adding 5 to 7 is 12 so we would get the equation 2x = 12

Next, we would divide 2x by 2 and divide 12 by 2 and we would get a quotient of 6.

Our final answer is x = 6

Answer:

x=6

Step-by-step explanation:

2x - 5 = 7

Add 5 to each side

2x-5+5= 7+5

2x = 12

Divide by 2

2x/2 = 12/2

x = 6
