The maximum value of P = 11.

Given: P = -x + 6y

In this question we have to first solve the given system of equations.

Ignore the greater or lesser than sign that is:

y = -2x+ 4 -------- 1

And y = x + 1 ---------  2

On solving these two equations we get;

0= -3x + 3

⇒ -3x = -3

⇒ x= 1

Substituting the value of x in equation 2 we get

y = x+ 1

= 1 + 1 = 2

Thus y = 2 and x = 1

So on putting these values in P = -x + 6y we get

P = - 1 + 6× 2

P = - 1 + 12 = 11

Therefore P= 11.

Using the similar triangle principle, the height of Dixon in feet is 6 feet.

Ariadne's shadow is 15 feet long and Dixon's shadow is 18 feet long.

Ariadne is 5 feet tall.

The height of Dixon can be found using similar triangle principle.

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.

Therefore, using the similar triangle theory,

Let

x = height of Dixon

Hence,

shadow length of  Ariadne / Ariadne height = Dixon shadow length / Dixon height

shadow length of  Ariadne = 15 ft

Ariadne height  = 5 feet

Dixon shadow length = 18 feet

15 / 5 = 18 / x

cross multiply

15 × x = 18 × 5

15x = 90

divide both sides by 15

15x / 15 = 90 / 15

x = 6 ft

Therefore, Dixon height is 6 feet.

If Jacob ran 10 miles in 80 minutes at that he will run the distance of 18.75 miles in [tex]2\frac{1}{2}[/tex] hours

Number of miles that Jacob will run in 80 minutes = 10 miles

Number of miles that Jacob will run in 1 minutes = Number of miles that Jacob will run in 80 minutes/ 80

What is linear equations?
Linear equations are a subset of first order equations. One homogeneous variable of degree one constitutes a linear equation in one variable (i.e., only one variable). A linear equation could contain multiple variables. When a linear equation comprises two variables, for instance, linear equations in two variables are utilized. A mathematical statement known as an equation contains an algebraic expression and the equal symbol (=). It is the equation for a straight line. The equation is shown to be valid when values are substituted for the unknown values in the solutions of linear equations. When there is just one variable, there is just one answer.

How to Solve?
Solving a linear equation involves determining the answer to a linear equation with one, two, three, or more variables. The answer to a linear equation is the value or values of the variable(s) that are part of the equation. There are six main ways to resolve linear equations. For the purpose of solving linear equations, these methods include the Graphical Method, Elimination Method, Substitution Method, Cross Multiplication Method, Matrix Method, and Determinants Method.

Let the greater of the two numbers be "x" and the smaller one be "y".
Given, x - y = 1200 --(i) & x + y = 6484 --(ii)
Adding (i) and (ii), we get, 2x = 7684 ⇒ x = 3842
Subtracting (i) from (ii), we get, 2y = 5284 ⇒ y = 2642
Thus, the greater number of the two numbers is 3842 and the smaller number is 2641.

The equation of the line will be y = -2x + 3.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation of the line that passes through the points (0,3) and (2,-1).

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

First calculate the slope of the line:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -1 - 3 ) / ( 2 - 0 )

Slope = -2

The y-intercept will be:-

y = mx + c

3 = 0 + c

c = 3

Equation of the line:-

y = mx + c

y = -2x + 3

The opposite of 0 is 0, the opposite of 7 is -7 and the opposite of 6 is -6.

If we consider a number x, then the opposite of the number x will be equal to -x. In a number line the opposite of a number lying on the positive side always lies on the negative side of number line. Also, the opposite of a number -x is the x that is the number itself. It is given in the question that we need to find opposite of 0, 7 and 6.

Let x = 0, opposite of x is -x.

=> -x = -0

=> -x = 0

Now, let x = 7, opposite of x is -x

=> -x = -7

Now, let x = 6, opposite of x is -x

[tex]\textsf{Exact form}: \quad x=-7 +\sqrt{49+e^3}[/tex]

[tex]\textsf{Decimal form}: \quad x=1.312\; \sf (3\:d.p.)[/tex]

Step-by-step explanation:

Given equation:

[tex]\ln x + \ln (x+14)=3[/tex]

[tex]\textsf{Apply the product law} \quad \ln x + \ln y=\ln xy:[/tex]

[tex]\implies \ln (x(x+14))=3[/tex]

[tex]\implies \ln (x^2+14x)=3[/tex]

[tex]\textsf{Apply the log law} \quad e^{\ln x}=x:[/tex]

[tex]\implies e^{\ln (x^2+14x)}=e^3[/tex]

[tex]\implies x^2+14x=e^3[/tex]

Subtract e³ from both sides to form a quadratic equation:

[tex]\implies x^2+14x-e^3=e^3-e^3[/tex]

Therefore:

Substitute these values into the quadratic formula and solve for x:

[tex]\implies x=\dfrac{-14 \pm \sqrt{14^2-4(1)(-e^3)} }{2(1)}[/tex]

[tex]\implies x=\dfrac{-14 \pm \sqrt{196+4e^3} }{2}[/tex]

[tex]\implies x=\dfrac{-14 \pm \sqrt{4(49+e^3)} }{2}[/tex]

[tex]\implies x=\dfrac{-14 \pm \sqrt{4}\sqrt{49+e^3} }{2}[/tex]

[tex]\implies x=\dfrac{-14 \pm 2\sqrt{49+e^3} }{2}[/tex]

[tex]\implies x=-7 \pm \sqrt{49+e^3}[/tex]

The cardinality of a set is a measure of the "number of elements" of the set. For example, the set contains 3 elements, and therefore. has a cardinality of 3.

Set A is the set of integers greater than -8 and less than -4.

Therefore set A = {-7, -6, -5,}

-7 is greater than -8 and -5 is less than -4 from the number line.

Therefore, set A = { -7, -6, -5 }

The probability of getting an even number greater than 800 is 0.08

Total outcomes possible when a three-digit number is formed without repetition:

Using the digits 3,4,5,6,7 and 8:

The first digit can be filled in using any of the 6 options

The second digit can be filled using the remaining 5 options

The third digit can be filled in using the remaining 4 options

So, total outcomes possible = 6*5*4 = 120 possibilities

Now, finding even number greater than 800:

The first digit can only be filled by 8 for a number to be greater than 800 which means there is only one option for the first digit

The second digit can be filled using any of the remaining options except 8 which means there are 5 options

The last digit can be filled using 4 and 6 because these are the only even numbers which mean 2 options

Total possible outcomes = 1*5*2 = 10 possibilities

The probability that the number is even and greater than 800:

= 10/120 = 0.08

Answer:

Range: [30,33]

Step-by-step explanation:

A Range is all possible values of a certain variable or piece of information commonly notated by a minimum and maximum. In this example, our variable is the speed traveled by drivers in a road. We are provided a minimum of 30 mph as this is the speed limit, and told that drivers may speed up to a maximum of 3 mph faster ( or 33 mph).

Therefore, our minimum would be 30, maximum would be 33, and Range would be [30, 33].

Brackets are used here because both our minimum and maximum values are included in the range.
