We have -2 from the values in the provided solution set, which is the necessary value.

what is solution set?

A solution set is a group of values in mathematics that satisfy a specified set of equations or inequalities. A constrained optimization problem's viable zone is its solution set of constraints.

Given: - 5x - 15 > 10 + 20x

Let's eliminate the variable x in order to solve the inequality.

5 times both sides,

- 5x - 15 + 5x > 10 + 20x + 5x

- 15 > 10 + 25x

Subtracting 10 from both sides

- 15 - 10 > 10 - 10 + 25x

- 25 > 25x

Dividing both sides by - 25

-1 > x

x < - 1

Step-by-step explanation:

Given function:

[tex]f(x)=2x-1[/tex]

where:

----------------------------------------------------------------------------------------------------

f(1) means the value of the function when x = 1.  

Therefore, substitute x = 1 into the given function to find f(1):

[tex]\begin{aligned}x=1 \implies f(1)&=2(1)-1\\&=2-1\\&=1\end{aligned}[/tex]

[tex]\begin{aligned}x=4.5 \implies f(4.5)&=2(4.5)-1\\&=9-1\\&=8\end{aligned}[/tex]

As the faces of the six-sided die are labelled 1 to 6, the only values of x that make sense are 1, 2, 3, 4, 5 and 6.  Therefore, rolling a "4.5" does not make sense.

f(10) means the value of the function when x = 10.

Therefore, substitute x = 10 into the given function to find f(10):

[tex]\begin{aligned}x=10 \implies f(1)&=2(10)-1\\&=20-1\\&=19\end{aligned}[/tex]

As the faces of the six-sided die are labelled 1 to 6, the only values of x that make sense are 1, 2, 3, 4, 5 and 6.  Therefore, rolling a "10" does not make sense.

[tex]\textsf{$f(10) = \boxed{19}$ , meaning when a $\boxed{10}$ is rolled on the die, the player is awarded} \\\\ \textsf{ $\boxed{19}$ points. This interpretation $\boxed{\sf does \; not \; make \; sense}$ in the context of the problem.}[/tex]

----------------------------------------------------------------------------------------------------

The domain of a function is the set of all possible x-values.

As the faces of the six-sided die are labelled 1 to 6, the only possible values of x are 1, 2, 3, 4, 5 and 6.  

[tex]\textsf{Based on the observations above, it is clear that an appropriate domain for the}\\\\ \textsf{function is $\boxed{ \{1, 2, 3, 4, 5, 6\}}$ .}[/tex]

The domain can also be written as:

[tex]\{x \in \mathbb{N} \; | \; 1 \leq x \leq 6 \}[/tex]  

or [tex]\{x \in \mathbb{Z} \; | \; 1 \leq x \leq 6 \}[/tex]

The choice that is true are:

f(0) > g(0)

f(6) = g(12)

f(-4) = g(-4)

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 4x + 2

g(x) = (5/2)x - 4

Now,

f(0) = 2

g(0) = -4

f(0) > g(0)

f(6) = 24 + 2 = 26

g(12) = (5/2) x 12 - 4 = 30 - 4 = 26

f(6) = g(12)

f(-4) = -16 + 2 = -14

g(-4) = -10 - 4 = -14

f(-4) = g(-4)

f(2) = 8 + 2= 10

g(2) = 1

f(2) > g(2)

Thus,

f(0) > g(0) is true

f(6) = g(12) is true

f(-4) = g(-4) is true

g(2) > f(2) is not true

Answer:

The expression √x+5+√1-x is defined for all values of x such that the value under the square root sign is non-negative. We can find the values of x that satisfy this condition by considering each of the square roots separately.

For the first square root, the value under the square root must be non-negative, so we have the following inequality:

x + 5 ≥ 0

x ≥ -5

For the second square root, the value under the square root must be non-negative, so we have the following inequality:

1 - x ≥ 0

x ≤ 1

Therefore, the expression is defined for all values of x that satisfy both of these inequalities. This means that the expression is defined for values of x in the range -5 ≤ x ≤ 1. The correct answer is therefore option D.

The cos(m) In the right triangle lmn is  19/20.

Complementary angles are formed when the total of two angles equals 90 degrees. 30 degrees and 60 degrees, for example, are complementary angles.

We have L + M = 90 because the angles L and M are complimentary.

Assuming that,

sin L = sin (90 - L) = sin M

sin (L) = 19/20.

As we know from our rule, the sine of angle L is equal to the cosine of L's complement, which is M.

This implies that the cosine of M is 19/20.

As a result, cos(M) equals 19/20.

6 socks must be removed from the drawer to guarantee that at least two socks of same color have been removed.

Given,

It makes no difference how many socks there are; what matters is how many different colours of socks there are, as there are five different colours.

So, if 6 socks are taken from the drawer, it is almost certain that at least two of them will be the same colour.

Because, after taking 5 socks, you will either have a match or a difference. To ensure a matching pair, add one more sock.

You have a pair if the first five are the same colour. If none of the first five socks match, the sixth sock will match one of the first five.

So with 6 socks, you are guaranteed that at least 2 of them will be the same color.

Kinetic Energy is referred to as "energy possessed by an object as a result of its MOTION".

What is Kinetic Energy?

The energy that an item or particle has as a result of its motion is known as kinetic energy. An object accelerates and gains kinetic energy when work—the transfer of energy—is done on it by exerting a net force.

An object in motion always has a velocity, or "v," at any given moment. This energy is referred to as "kinetic energy," and it comes from:

Kinetic Energy = 12×m×v2

Here, m = Mass of the object in motion

Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. A moving object or particle has kinetic energy, which depends on both its mass and its rate of motion. The type of motion can be vibration, rotation on an axis, translation (or travel along a path from one place to another), or any combination of these.

A body's translational kinetic energy is equal to 1/2mv2, which is the product of its mass, m, and square of its velocity, v.

To find the account balance after 17 years, we need to first calculate the annual interest rate. Since the interest is compounded 4 times per year, the effective annual interest rate is equal to (1 + 0.04/4)^4 - 1, which is about 4.169%.

To find the account balance after 17 years, we can use the formula for compound interest: A = P(1 + r/n)^(nt), where A is the final amount, P is the initial principal, r is the annual interest rate, n is the number of times the interest is compounded per year, and t is the number of years. Plugging in the values we know, we get:

A = 5360(1 + 0.04169/4)^(4*17)

A = $9,907.35

So the account balance after 17 years will be about $9,907.35.

This is just an estimation, as the actual time it would take Jamie to swim the length of the pool would depend on factors such as Jamie's swimming ability and the speed at which they swim.
