The number of concert shows that singer A and singer B attended will be 41 and 18 shows respectively.

Based on the information, the equation for last year will be:

A = 2B + 5

The number will be illustrated as:

A = B + 23

Therefore, it should be noted that we will equate the expression. This will be:

2B + 5 = B + 23.

Collect like terms

2B - B = 23 - 5

B = 18.

A = 23 + B = 23 + 18 = 41

The solution using indices for the given equation is (x = 5/3).

For the given expression in question;

8 × 8⁴ˣ⁻³ = 512 × 8ˣ

By the property of indices, if the base is equal; then the powers are added with sign.

8⁴ˣ⁻³⁺¹ = 512 × 8ˣ

As, we know that 512 is the cube of 8.

8⁴ˣ⁻² = 8³ × 8ˣ

Apply the power law on right side;

8⁴ˣ⁻² = 8³⁺ˣ

As, the base on both side is equal, then the exponents are also equal.

Thus,

4x - 2 = 3 + x

Bring variables and constants on different sides.

4x - x = 3 + 2

3x = 5

x = 5/3

Therefore, the value of x is found as 5/3.

Answer: c

Step-by-step explanation:

The  absolute difference is 492 people per square mile and Relative difference: 435.4%.

Thus, option (B) is correct.

To find the absolute difference between the two population densities, subtract the population density of country A from the population density of country B:

Absolute difference = Population density of country B - Population density of country A

                                 = 605 people per square mile - 113 people per square mile

                                 = 492 people per square mile

Now, the relative difference as a percentage, we use the formula:

Relative difference = (|Absolute difference| / Population density of country A) * 100

                                = (|492| / 113) * 100

                               = (492 / 113) * 100

                               = 4.35398230088 * 100

                               = 435.4%

Therefore, the absolute difference is 492 people per square mile

Relative difference: 435.4%

The value of the function f(x + a) - f(x) is √(x + a - 9) - √(x - 9)

The function definition is given as

f(x) = √(x - 9) + 6

We start by calculating the function f(x + a)

So, we have

f(x + a) = √(x + a - 9) + 6

The function definition f(x + a) - f(x) is calculated as

f(x + a) - f(x) = √(x + a - 9) + 6 - (√(x - 9) + 6)

Open the bracket

So, we have

f(x + a) - f(x) = √(x + a - 9) + 6 - √(x - 9) - 6

Evaluate the difference

So, we have

f(x + a) - f(x) = √(x + a - 9) - √(x - 9)

Hence, the value of the function f(x + a) - f(x) is √(x + a - 9) - √(x - 9)

In order to be able to compensate to get the exact sum of the two prices, Kayla should subtract $0.05 from $55.75.

In order to be able to get the price of $55.75, Kayla rounded $34.95 up to $35 and then added $20.75.

To compensate for the rounding up and then get the exact sum of the prices of the sweaters, Kayla should subtract the difference between the $35 and the $34.95.

Given the change in altitude and time, the mean change of altitude of the airplane is -63 ft/min.

The mean change of altitude is simply know as the average rate of change.  

The average rate of change is the sum total of the change in altitude divided by the sum total of the change in time.

It is expressed as;

r = Δa/Δt

Where r is rate of change, Δa is total change in altitude and Δt is the total change in time.

Given the data in the question;

Plug the given values into the above formula and solve for r.

r = Δa/Δt

r = -378ft /  6min

r = -63 ft/min

The inequality to determine the number of outfits Zendaya can purchase while staying within her budget is

     269.88 + 4*10.57 + 17.76 + 65.65x ≤ 540

And the number of outfits Zendaya can buy is 3 .

According to the question we have been given that the

 Total money Zendaya has = $540

  Cost of new bicycle = $269.88

   Cost of bicycle reflectors = $10.57

   Cost of bike gloves = $17.76

  Cost of biking outfits = $65.65

Let the number of outfits Zendaya purchases be x.

The inequality to determine the number of outfits Zendaya can purchase while staying within her budget is

     269.88 + 4*10.57 + 17.76 + 65.65x ≤ 540

Now solving this inequality for x we get

     269.88 + 42.28 + 17.76 + 65.65x = 540

    329.92 + 65.65x = 540

In mathematical expression the given expression is written as;

⇒ S + 12 = x² + 2x + 4

Where, S is area of square with side x.

What is Area of square?

A square is a two dimension figure in which all the sides are equal. Since all the sides are equal, the area would be two times the side of a square.

Let a side of square is x feet.

Then, Area of a square (S) = x²

When, The side of the square is increased by 2 feet. Then area is increase by 12 sq. ft.

Then, Side of a square = (x + 2)

Hence, Area of a square = (x + 2)²

                            s + 12  = x² + 2 * x * 1 + 2²

                            s + 12 = x² + 2x + 4

Answer:

The values of x are -6 + √5 and -6 - √5.

Step-by-step explanation:

It is given that we need to find all of the points of the form (x,-1) which are 3 units from the point (-6, 1).

Now, let us suppose that these points are in 2D coordinate system such as;

=> (x1, y1) = (-6, -1)

and let us suppose that the other point is;

=> (x2, y2) = (x, 1)

Further, the distance between both these points them is 3 units and we can write this as;

=> d = √(x1 - x2)² + (y1 - y2)²

=> 3 = √(-6 - x)² + (-1 - 1)²

After squaring both the sides;

=> 9 = 36 + x² + 12x + 4

=> 9 = x² + 12x + 40

On rearranging the equation;

=> x² + 12x + 31 = 0

Now, this is a quadratic equation of the form ax² + bx + c = 0 in which;

=> x = -b ± √(b² - 4ac) / 2a

After putting values in this for obtaining the value of x on comparing we get;

=> x = -12 ± √(12² - 4×31) / 2

=> x = -12 ± √(144 - 124) / 2

=> x = -12 ± √20 / 2

=> x = -12 ± 2√5 / 2

=> x = 2(-6 ± √5) / 2

=> x = -6 ± √5

Therefore, the values of x are -6 + √5 and -6 - √5.

Answer:

Step-by-step explanation:

By using trigonometric relations, we can see that the hypotenuse of the right triangle measures 30.8 units.

Here we will need to use trigonometric relations. We want to find the value of x, which is the hypotenuse of the right triangle.

We know the measure of one angle, and the adjacent cathetus to said angle, the measures are:

angle = 65°

Cathetus = 13 units.

Now we can sue the trigonometric relation:

cos(a) = (adjacent cathetus)/(hypotenuse)

Replacing what we know, we can rewrite that as:

cos(65°) = 13/x

Now we just need to solve the equation for x, we will get:

x = 13/cos(65°) = 30.8 units.

We conclude that the hypotenuse of the right triangle measures 30.8 units.
