Graph the image of the figure using the transformation given.
(its multiple choice!)

Answers

The answer is B. Reflection across x=-3. This is the answer because the shape is reflecting across the imaginary line of x=-3

The original image undergoes reflection across x=-3.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

In the given graph DEFG is the original image.

D'E'F'G' is the new image after the transformations applied.

A reflection is defined by the axis of symmetry or mirror line. In the above diagram, the mirror line is x = -3.

Under reflection, the shape and size of an image is exactly the same as the original figure.

This type of transformation is called isometric transformation.

Hence, the original image undergoes reflection across x=-3.

4x +40 = 80
Step by step how to solve?

Answers

Answer:

x=10

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

4x+40=80

Step 1: Subtract 40 from both sides

4x+40−40=80−40

4x=40

Step 2: Divide both sides by 4

4x/4=40/4

Answer:

x=10

Answer:

collect like terms

4x=80 - 40

4x= 40

divide both sides by 4

4x/4÷ 40/4

x = 10

Step-by-step explanation:

6 is not a factor only terms count as factors

The number 6 is the only number in the expression. Then the correct option is 2.

What is factorization?

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

Simply said, it is the biggest common element. The highest consistent element in the above example is 15, making 15 the greatest common factor amongst 15, 30, and 105. The biggest chunk of the common factors is called the "Greatest Common Factor" (of two or more numbers).

The expression is given below.

⇒ (b + 6)

The number 6 is a factor only terms count as factors because the variable b is the multiple of 6.

The number 6 is the only number in the expression. Then the correct option is 2.

A sign in front of a roller coaster says "You must be 40 inches tall to ride." What percentage of this height is: (use whatever strategy you would like)

Answers

The question is incomplete. The complete question is :

A sign in front of a roller coaster says ''you must be 40 inches tall to ride". What percentage of this height is A). 34 inches and B). 54 inches

Solution :

It is given that " You must be 40 inches tall to ride."

The formula used will be :

% [tex]$=\frac{V}{T} \times 100$[/tex]

Where, V is the value of the percentage to be calculated

T is the value out of which the percentage of V is to be calculated.

A). What percentage of 40 inches is 34 inches

Where, V is 34 inches and T is 40 inches.

Therefore, the percentage of 34 inches in 40 inches will be

[tex]$\frac{34}{40} \times 100$[/tex]

= 85 %

B). What percentage of 40 inches is 54 inches

Where, V is 54 inches and T is 40 inches.

Therefore, the percentage of 54 inches in 40 inches will be

[tex]$\frac{54}{40} \times 100$[/tex]

= 135 %
