The property of real numbers illustrated by the equation  - [ -(x - 10)] = x-10 is Distributive property.

Distributive Property of real number is represented by the expression

a(b+c)=a*b+a*c.

For Example : 3(2+4)=3*2+3*4

                                  =6+12

                                  =18

In the given question ;

LHS  =-[-(x-10)]

First applying distributive property in side "[ ]".            

=  -[-x-(-10)]

= -[-x+10]   

Again applying distributive property , we get

= -(-x)-(+10)

= x-10  =RHS

Therefore , Distributive Property of Real numbers is illustrated by the equation  - [ -(x - 10)] = x-10.

The standard form is 3/2x + y +2 = 0 for line perpendicular to -2 x+3 y=9 through (-1,-3)

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

See, that was so simple, using the mentioned methods, every linear equation can be solved easily.

In an equation, parallel lines have the opposite reciprocal slope. In other words, if a line's slope is a positive fraction, its reciprocal slope is negative.

Here given that  -2 x+3 y=9

can also be written as

y = 2/3x + 3

Here -2/3 is the slope and 3is the y-intercept

To find a parallel line to the following equation, use the opposite reciprocal slope and point, then solve using the point-slope formula.

y - y₁ = m(x - x₁)

We have, m = -3/2 x₁ = -1 and y₁ = -3

y - (-3) = -3/2(x - (-1))

y + 3= -3/2x +1

3/2x + y +2 = 0

We have the standard form 3/2x + y +2 = 0 of a line  perpendicular to y = (2/3)x - 1 through (0,6)

The height of the tree is 2.22 feet so that the point on the ground is 70 ft from the base of a tree

An equation is an expression that shows the relationship between two or more numbers and variables.

Let h represent the height of the tree. Hence the distance to the top of tree = 3h + 2.

Using Pythagoras theorem:

(3h + 2)² = h² + 70²

9h² + 12h + 4 =  h² + 70²

8h² + 12h - 66 = 0

h = 2.22 feet

The equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.

A straight line is represented using its slope and a point on the line using point slope form. In other words, the point slope form is used to determine the equation of a line whose slope is "m" and passes through the point (x1, y1).

given that

the coordinates points are (4, 6) and (10, 30)

(x1,y1) = (4,6)

(x2, y2) = (10,30)

The formula of point-slope is

(y - y1) = m(x - x1)

Here,

x1 = 4 and y1 = 6 but we don't know the value of

m.

now,find the value of m using the following formula

[tex] m = \frac{(y2 - y1)}{(x2 - x1)}[/tex]

now, substitute the values, we get

[tex]m = \frac{(30 - 6)}{(10 - 4)}[/tex]

[tex]m = \frac{24}{6}[/tex]

m = 4

so, the value of m is 4.

substitute these values into the point-slope formula

(y - 6) = 4(x - 4)

y-6 = 4x - 16

y = 4x -16 + 6

y = 4x - 10

-4x + y + 10 =0

Hence, the equation of point slope form of (4,6) and (10,30) is -4x + y + 10 = 0.

Comparing the functions f(x) = ln (x) and [tex]f^{-1}(x) = e^x[/tex], we can conclude that the domain of [tex]f^{-1}(x)[/tex] is all real numbers and the range is all real numbers greater than 0.

Given function is the logarithmic function f(x) = ln(x).

Now, f(x) has a domain(D) of all real numbers greater than zero and a range(R) of all real numbers.

i.e., f : D → R defined by f(x) = ln(x)

So if an inverse exist for f(x), then, [tex]f^{-1}(x)[/tex] will have R as its domain and D as its range.

i.e.,  [tex]f^{-1}[/tex] : R → D defined by [tex]f^{-1}(x) = e^x[/tex].

Answer:

Step-by-step explanation:

By elimination, the system of equations, 9a - 3d = 3 and -3a + d = -1, has infinite solutions.

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using the elimination method, given two equations in a and d, a variable should be eliminated by adding/subtracting the two equations.

Simplifying the first equation by dividing it by -3,

9a - 3d = 3 ⇒ -3a + d = -1     (equation 1)

-3a + d = -1     (equation 2)

Since the simplified equation of the first equation is the same as the second equation, then the two lines are exactly the same or overlapping.

Hence, the system of equations has infinite solutions.

From figure we can say that there is present five rectangle of same size.

So far finding the area of this irregular figure we have to find the area of this single rectangle and multiply it by 5 so from that process we can calculate the area of this irregular figure.

Now first we have to learn about the area,

The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a shape or planar lamina.

So, we know

The area of one rectangle = l x w

Now, putting the values = 3 x 2 = 6

So,

The area of this irregular figure = 5 ( The area of one rectangle )

                                                   = 5 x 6

Step-by-step explanation:

Answer:

m = 3/19

Step-by-step explanation:

Let's solve your equation step-by-step.

19m = 3

Step 1: Divide both sides by 19.

19m/19 = 3/19

- You might be wondering, why do we need to divide both sides by 19? -

Well, to find m, you need to get it by itself. So by dividing 19m by 19, m stands alone. But again, what we do to one side, we need to do to the other. So 3 must also be divided by 19.

Answer:

m = 3/19

Step-by-step explanation:

(a+b)² = (a+b) × (a+b)

The quantities X and Y are proportional as y = rx  then the constant of proportionality r is 1/9.

Firstly, there is proportional relationship.

Two values x  and  y are said to be in a proportional relationship if x=ky, where x and y are variables and k is a constant.

The constant k is called constant of proportionality.

WE have been given quantities X and Y are proportional

y = rx

Where r is constant of proportionality.

Then x = 45 and y = 5

Thus,

y = rx

5 = 45r

Now divide by 45 on both side;

r = 5/45

r = 1/9

We will rewrite this equation in the exponential form by considering the definition of logarithm.

The definition states that,

If x and b are two positive real numbers and the value of b is not equal to 1, then the log of

log b (x)=y is equivalent to by=x

We will convert the given equation according to the above definition,

2x=16

The bases of all the values involved must be identical. So, we will create equivalent expressions in the equation that all have equal bases.

A variable, a number, or a mix of numbers, operations, and numbers symbols make up an expression. Two expressions joined by an equal sign form an equation.

A formula called an equation uses the equals symbol (=) to denote the equality of two expressions.

Consider the expression,

1/2x + 1/2x + x + 1

Taking common out,

( 1/2 )x + ( 1/2 )x + x + 1 = ( 1/2) × [ x + x ] + x + 1

( 1/2 )x + ( 1/2 )x + x + 1 = (1/2x) × 2 + x + 1

Using two points on the line, say, (-2, 0) and (3, -4), follow the steps below to find the equation of the line:

Step 1: Find the slope of the line

Slope (m) = (-4 - 0)/(3 -(-2))

Slope (m) = -4/5

Step 2: Find the y-intercept (b)

Substitute m = -4/5 and (x, y) = (-2, 0) into y = mx + b

0 = -4/5(-2) + b

0 = 8/5 + b

0 - 8/5 = b

b = -8/5

Step 3: Substitute m = -4/5 and b = -8/5 into y = m + b

y = -4/5x - 8/5
