The absolute value equation for each of the graphs are |x + 3| = 2 and |x - 4| = 1 respectively.

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

An inequality shows the non equal comparison of numbers and variables.

A) For the inequality shown, the midpoint is [(-1) + (-5)]/2 = -3. The distance from each of the endpoint to the midpoint is 2 units (i.e. from -1 to -3 or from -5 to -3). Hence:

Absolute inequality is:

|x - midpoint| = distance from endpoint to midpoint

This gives:

|x - (-3)| = 2

|x + 3| = 2

B) For the inequality shown, the midpoint is [3 + 5]/2 = 4. The distance from each of the endpoint to the midpoint is 1 units (i.e. from 3 to 4 or from 5 to 4). Hence:

Absolute inequality is:

|x - midpoint| = distance from endpoint to midpoint

This gives:

|x - 4| = 1

The absolute value equation for each of the graphs are |x + 3| = 2 and |x - 4| = 1 respectively.

Answer: 36 feet of wood

Step-by-step explanation:

P=perimeter. P=total length of wood

s= side length. A=area

A=s^2

81=s^2

s^2=9^2

s=9

P=4s

P=4(9)

P=36 feet of wood

Answer:

P = 36 ft

Step-by-step explanation:

The given length is,

→ a = ?

Formula we use,

→ A = a²

Now the length of one side is,

→ A = a²

→ a² = 81

→ a = √81

→ [ a = 9 ]

The total length of wood needed is,

→ P = 4a

→ P = 4 × 9

→ [ P = 36 ]

Hence, the total length is 36 ft.

A function exists described as a relation between a set of inputs containing one output each. The value of h(g(3)) is 5.

A relationship between a group of inputs and one output is referred to as a function.

In plain English, a function is an association between inputs in which each input is connected to precisely one output.

A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

Where, g(3) = 0

To get h, replace g(3) with 0 in the requested equation (0).

Since h(0) = 5 according to the question, your final response is 5.

Therefore, the value of h(g(3)) is 5.

Step-by-step explanation:

  Multiply 3 with 5 and multiply 3 with b and then add the results of the multiplication.

3*(5 + b) = (3*5) + (3*b)

Applying the midpoint formula, the coordinates of B are: (-7, 4).

The midpoint formula is:

M(x, y) = [(x2 + x1)/2, (y2 + y1)/2]

Given:

M(x, y) = (-3, 0)

A(x1, y1) = (1, -4)

B(x2, y2) = (?, ?)

Plug in the values into the midpoint formula:

M(-3, 0) = [(x2 + 1)/2, (y2 + (-4))/2]

Isolate each coordinate

-3 = (x2 + 1)/2

-6 = x2 + 1

-6 - 1 = x2

x2 = -7

0 = (y2 - 4)/2

0 = y2 - 4

y2 = 4

Therefore, applying the midpoint formula, the coordinates of B are: (-7, 4).

Given equation x + 2y = 15 and 3x -15 = -6y are real numbers so the equation has a solution.

Some equations have no solutions. In these equations, there is no value for the variable that makes the equation true. You can tell that an equation has no solutions if you try to solve the equation and get a false statement.

We have been given that

x + 2y = 15 ..........(1)

3x -15 = -6y ..........(2)

Multiply equation (1) with 3.

3(2y+x)=5

6y+3x=-15

Subtract equation (1) from equation (2)

0=15

Instead of 6y+3x=-15, 3x-15=-6y becomes 6y+3x=15. So, these 2 equations are saying the same thing (this is the first equation times 3), and therefore the solution is all real numbers.

Hence, The equation has a solution since the given values of x + 2y = 15 and 3x -15 = -6y are real numbers.

The measure of each of the small arcs of the circled glass stained window is 45°.

Congruent in circle:

Circles having the same radii are said to be congruent of one another.

For example,

When two circles are congruent, we can also say that they have the same area and circumference. Thus they can also be said to be equal circles.

Given,

In the stained glass window design, all of the small arcs around the circle are congruent. Suppose the center of the circle is point O.

Here we need to find the measure of each of the small arcs.

We know that.

Congruent circles can be defined as circles which are having the same or equal radii.

So, based on this the circle we need to divided it as equal radius arcs.

We know that, the measurement of the full circle is 360°.

So, here we have to divide it by 8.

Then we have each arc as,

We know that the businessman earns a basic salary of $1000 (it does not depend on how many items he sells) and $500 for each item he sells as a commission.

Then, if we define x as the number of items he sells, the amount he gets in commissions is: x*$500

to find the y intercept of AB, first find the slope of AB: m=(1-(-1))/(2-14)=-1/6

the equation of line AB is y=-(1/6)x+b

use either of the given two points to find out b: 1=(-1/6)*2+b => b=4/3

BC is perpendicular to AB, so the slope of BC is the negative reciprocal of the slope of AB, therefore, the slope of BC is 6

Equation of BC is y=6x+b

find out b by using the coordinates of point B: 1=6*2+b => b=-11

the equation of BC is: y=6x-11

Step-by-step explanation:

The area is 599.5 square feet and it is 22 feet wide. So in order to find the area we have to multiply the width (22 feet wide) and the legth (unknow number which will stand for "x"). Since we area multiplying the width and legth we need to do the inverse operation which is dividing. We didvide the area 599.5 by the width 22 to get 27.25 feet long.

22x = 599.5

----- -------- <------ Fraction bar/divide
