Looks like the whole equation was

[tex]y = 2.5x + 3[/tex]

So it's asking to choose a random x value, well choose 2 I guess. You'll plug that in where X is

[tex]y = 2.5(2) + 3[/tex]

Now after we work this out, Y should equal 8 because that's the Y value right below 2 on the table. If it equals 8, then the equation is correct.

The inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

Inverse of a function can be calculated by following the steps mentioned below -

According to the question, the equation given is as follows

y = f(x) = 2x + 5

y = 2x + 5

Replace 'y' with 'x', we get -

x = 2y + 5

Now, solve for y -

2y = x - 5

y = (x/2) - (5/2)

Replace 'y' with f⁻¹(x) -

f⁻¹(x) = (x/2) - (5/2)

Hence, the inverse of the function → f(x) = 2x + 5  is → f⁻¹(x) = (x/2) - (5/2).

WXYZ is a parallelogram.

A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.

here, we have,

The slope of both sides is needed in order to determine whether they are parallel

The slope of a line connecting two points is just the change in y over change in x.

so, we get,

WX

m_1 = (1 - 5)/(-2 -1)

m_1 = -4/-3

m_1 = 4/3

Answer: 7/9

Step-by-step explanation:

The ratio of AP to PB is 3 to 2 then the point P exists (8, 2).

An area or portion of a line with two endpoints is known as a line segment. A line segment has a set length as opposed to a line. Both metric measurements, such as millimeters and centimeters, as well as conventional units, such as feet or inches, can be used to measure the length of a line segment.

An uncurved path with two ends is called a line segment. With points at either end, a line segment is drawn.

The arrowheads at both ends are used to portray it as a straight, lengthy, and continuous road. It stretches out both ways. The straight line that connects two places is called a line segment.

Since 3+2 = 5, we are dividing line segment AB into 5 congruent parts with point P 3/5 of the way from A to B.  

x-coordinate of P = x-coordinate of A + (3/5)(change in x from A to B)

= -4 + (3/5)(20) = 8

y-coordinate of P = y-coordinate of A + (3/5)(change in y from A to B)

= 8 + (3/5)(-10) = 2

P = (8, 2)

The complete question is:

The values of x for which the above expression can become rational is -

[5, 14, 25]

We must convert a given number to decimal form in order to determine whether it is rational or irrational. If the decimal has repeated decimal patterns and is ending or nonterminating, the number is rational.

If not, it is illogical. However, if we look at the example of 5 = 2.2360679774997896409173..., we can see that it is non-terminating and lacks repeated decimal patterns. It is therefore an irrational number. Checking whether a number is a natural number, a whole number, an integer, or a fraction of integers is another method of determining whether it is rational. It is a rational number if it fits into one of these categories.

Given the expression is √x+11,

√a It cannot be expressed in the form of a ratio, So, it is an irrational number.

The value of x has to be something which upon adding 11, gives perfect square root, in order to become rational number.

So, the number that can have possible values is x ≥ 5; √x+11 = perfect square root.

The values of x for which the above expression can become rational is -

[5, 14, 25]

The value will be - √5 + 11 = √16 = 4

The value will be - √14 + 11 = √25 = 5

The value will be - √25 + 11 = √36 = 6

The result is. It indicates that there exist 17 units between the two points supplied as the answer to the given distance problem.

An object's travels are quantified by distance. Simply explained, distance, or t, is the amount of space an object covers within a specific period of time. Displacement is still the quickest route a moving object can travel. We frequently take into account the concepts of distance and motion.

Here,

the numbers (6, -3) & (2, -2)

The distance among points (a, b) and (c, d) is now

d= √(c-a)² + ( d- b) ( d- b) ²

Consequently, d= (-3+2)2 + (2-6)2

d= √ 1 + 16

d= √17

Therefore, there are 17 units between the two places.

As a result. The answer to the above distance calculation issue indicates that there are 17 units between the two points.

Answer:

14=90

Step-by-step explanation:

You're on the right track with writing the measure of MK = angle N. To figure out angle N we can use the right angle sign right next to it (at LNK). We know that line JK is a straight line meaning it's angle = 180. Therefore, if LNK is 90 degrees, then N also has to be 90 degrees because 90+90=180. From there we know that the measure of MK = 90 due to MK and N being vertical angles.

The y-intercept of the equation is 5.

What are intercepts?

A point on the y-axis known as an intercept is where the line's slope passes.

X-intercept and Y-intercept are the two main intercepts. The line's x-intercept and y-intercept are located where the line crosses the x and y axes, respectively.

We are given two points (2, 11) and (3, 14).

First, we need to form the equation.

General form of a point slope form of equation is y-y₁=m(x-x₁)

Here, y₁= 11 and x₁= 2, y₂= 14 and x₂=3

Now, m = (y₂ - y₁) / (x₂ - x₁)

⇒m = (14 - 11) / (3 - 2)

⇒m = 3

Thus, we get the equation as y-11 = 3(x-2)

In order to find the y-intercept, we need to put x=0

So,

⇒y-11 = 3(0-2)

⇒y = -6 + 11

⇒y = 5

Hence, the y-intercept of the equation is 5.

The system of equations is solved and the amount of 45 % copper is 34.74 pounds and the amount of 64 % copper alloy is 20.26 pounds

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total amount of the third alloy = 55 pounds

So , the amount the 45 % of copper alloy = x

And , the amount of 64 % of copper alloy = ( 55 - x )

The percentage of amount of alloys is given by the equation ,

( 45/100 )x + ( 64/100 ) ( 55 - x ) = ( 52/100 ) 55

On simplifying the equation , we get

0.45x + 0.64 ( 55 - x ) = 0.52 ( 55 )

0.45x + 35.2 - 0.64x = 28.6

Subtracting 35.2 on both sides of the equation , we get

-0.19x = -6.6

Divide by 0.19 on both sides of the equation , we get

x = 34.736

x ≈ 34.74 pounds

Hence , the amount of 45 % of copper alloy is 34.74 pounds and the amount of 64 % copper alloy is 20.26 pounds
