The given functions are

r(x) = - 2x - 2

s(x) = x^2 + 2

To find s(r(4)), the first step is to substitute x = - 2x - 2 into s(x) = x^2 + 2. Thus, we have

s(r(x)) = (- 2x - 2)^2 + 2

s(r(x) = (- 2x - 2)(- 2x - 2) + 2

s(r(x) = 4x^2 + 4x + 4x + 4 + 2

s(r(x)) = 4x^2 + 8x + 6

Finally, we would substitute x = 4 into s(r(x) = 4x^2 + 8x + 2. Thus, we have

s(r(4)) = 4(4)^2 + 8(4) + 6

s(r(4)) = 64 + 32 + 6

s(r(4)) = 102

To find: The value of x.

Explanation:

It is given that,

That implies,

Hence, the value of x is 4.

SOLUTION:

If the value of a lies in between - 1 and 1 in the absolute value function y = a|x|, then the graph is farther from the y- axis. This is because the bounding lines of the function are the lines y = x and y = -x. Thus, when a varies from -1 to 1, the graph gets farther from the y-axis.

The total money Isabella spent on tickets will be $1362.48

In the given question, it is stated that Isabella bought a total of 84 Tickets. Each of the tickets she bought cost $16.22. We have to find out the total amount that she spent on buying tickets for everyone. From this given situation we know:

The cost of one ticket: $16.22

Total number of tickets: 84

From this formula, we can calculate the total amount spent

Total Amount = Total ticket * cost of one ticket

Putting values in this formula, we get:

=> Amount = cost*number

=>  Amount = 16.22*84

=>  Amount = 1362.48

Hence, the Total amount that she spent on Tickets will be $1362.48

We will say that x is the salary before the raise, to calculate how much the salary grows, we just have to take the given percent from x, in this case, the payment increased by 4% (0.04 expressed in decimal form) then the increased amount would be x times 0.04.

Salary increase = x*0.04 = 0.04x

Adding 0.04 x to the original salary x (before applying the increase) we get the actual monthly salary, $2,496, then we can formulate the following expression:

Current salary = original salary + salary increase

2,496 = x + 0.04x

From this equation, we can solve for x like this:

1. Factoring x on the right side of the equation:

2,496 = x(1+0.04)

2. making the sum inside the parentheses:

2,496 = x*1.04

3. Dividing both sides by 1.04:

2,496 / 1.04 = x * 1.04 / 1.04

2400 = x

x = 2400

Then, Linda was making $2400 before the pay increase

To find the slope, we will use the formula;

slope = y₂ - y₁ / x₂- x₁

From the points give,

x₁ = -4 y₁= 10

x₂ = -4 y₂=3

slope = 3 - 10 / -4+ 4

slope = -7/0

slope = ∞

The slope is undefined.

Answer:

720

Step-by-step explanation:

Formula: P (n,r) = n! ÷ (n - r)!

n = Total number of objects in a set

r = The number of items you choose

Mark knows the account number includes the numbers 2,3,5,7,8, and 9. There are obviously 6 numbers in total in this set and 6 he must choose in order to have a 6 digit account number, which the problem also directly states he has.

That means P(n,r) = P(6,6)

!/Factorial = Product of all positive numbers less than or equal to the given positive number

Therefore, 6! = 1 x 2 x 3 x 4 x 5 x 6

P (n,r) = P(6,6) = 6! ÷ (6-6)! = 720

Answer: F. $1.25

Explanation:

First, we need to find the probability of the coin landing faceup and facedown. We know that landing faceup is 3 times the probability of landing facedown. Since the highest probability is 1 (100%):

With this, we know that:

probability of the coin landing faceup = 3×0.25 = 0.75

probability of the coin landing facedown = 0.25

To find the expected value of each toss, we need to solve for the total of each value multiplied by its probability:

Therefore, the expected value of each toss of Coin C is $1.25

Okay, here we have this:

According with the provided info we obtain the following equation:

The area of the rectangle with 8 and 3 1/2 units is 28 sq. units.

The region occupied by a rectangle within its four sides or boundaries is known as its area. The area of a rectangle is determined by its sides. Essentially, the formula for area is equal to the product of the rectangle's length and breadth.

It is given that the length of the rectangle is 8 units and the breadth 3 1/2 units.

the area of the rectangle = length x breadth = 8 x 3 1/2 = 8 x 7/2 = 28 sq. units

So, the area of the rectangle is 28 sq. units.

y = 11

EXPLANATION

wo lines are parallel if they have the same slope and diffenrent y-intercepts.

In this case, we have to write the equation of a line parallel to the line y = 8, which is a line with a slope of 0 - i.e. it is a horizontal line. Therefore, the equation of the line we have to find must have the same form - y equal to a constant. This constant is the y-coordinate of the point where the line must pass through, (-3, 11).

Hence, the equation of the described line is y = 11.

Answer:

Find x first.

Since angle EOG = 90°,

x = 90 - 54 = 36°

Angle AOD = angle COB = 156° (vertically opposite angles)

y + 54 + 36 + 2y = 156

3y + 90 = 156

3y = 66

y = 22°

Answer:

(-1, 3)

Step-by-step explanation:

We could imagine the point G and H are points on a straight line.

We know that:

Point G is at (-10, 14)

Midpoint at M (-4.5, 5.5)

To calculate the x coordinate of the mid-point, we suppose to subtract x coordinate of H from coordinate x of G, divide by 2 to get the x coordinate of the midpoint m, which is -4.5

To calculate the y coordinate of the mid-point, we suppose to subtract y coordinate of H from y coordinate of G, divide by 2 to get the x coordinate of the midpoint m, which is 5.5

Therefore, x coordinate of H:

(- 10 - x) / 2 = -4.5

-10 - x = -9

- x = 1

x = - 1

And y coordinate of H:

(14 - y) / 2 = 5.5

14 - y = 11

- y = -3

y = 3

Based on the calculations, the length (L) of this rectangle is equal to 5 feet.

A rectangle can be defined as a type of quadrilateral in which its opposite sides are equal and all the angles formed are right angle.

Mathematically, the area of a rectangle can be calculated by using this formula:

A = LW

Where:

Given the following data:

Area of rectangle, A = 35 square feet.

Width of rectangle, W = (L + 2) feet.

Substituting the given parameters into the formula, we have;

35 = L(L + 2)

35 = L² + 2L

L² + 2L - 35 = 0

Solving the quadratic equation by using the factorization method, we have:

L² + 7L - 5L - 35 = 0

L(L + 7) - 5(L + 7) = 0

(L + 7)(L - 5) = 0

Therefore, the length (L) of this rectangle is equal to 5 feet since the dimension can not be negative.

The function operation g( x - 1 ) of the function g( x ) = −4x − 1 is -4x + 3.

A function is simply a relationship that maps one input to one output.

Given the data in the question;

To find g( x - 1 ), replace all the occurrence of x with ( x - 1 ) in the function and simplify.

g( x ) = −4x − 1

g( x - 1  ) = −4( x - 1 ) − 1

Simplify by distributive property

g( x - 1  ) = −4( x - 1 ) − 1

g( x - 1  ) = x( -4 ) - 1( -4 ) - 1

g( x - 1  ) = -4x + 4 - 1

g( x - 1  ) = -4x + 4 - 1

Add 4 and -1

g( x - 1  ) = -4x + 3

Therefore, the function operation g( x - 1 ) is -4x + 3.
