Using the concept of function, it is found that:
- Graphs B, C, D and F are functions.
- Graphs A and E are not functions.
-----------------------------
- In a function, one value of the input can be related to only one value of the output.
- In a graph, it means that for <u>each value of x(horizontal axis), there can only be one respective value of y(vertical axis). </u>That is, if a vertical line is traced at a value of x, it can cross the function only once, that is, there cannot be points aligned vertically.
- In graphs B, C, D and F, it can be seen that <u>for each x value, there is only one respective y-value</u>, thus, they are functions.
- In graphs A and E, for <u>values of x,</u> such as x = 3 for both, there are <u>two respective values of y</u>, thus they are not functions.
A similar problem is given at brainly.com/question/12463448
You need at least 2 congruent angles , or 3 proportional sides , or 2 proportional sides and 1 congruent angle to prove that 2 triangles are similar.
I presume that there should be a picture attached to this question , but if you only have 1 side in proportion ( x ) , you cannot prove the similarity of two triangles.
But if there already were two proportional sides or 1 proportional side and one congruent angle , you can prove they are similar if x = 48
Hope it helps
Answer:
4
Step-by-step explanation:
Use PEMDAS. Use a calulator to solve 3 and 1/3 times 1.9+19.5 divided by 4 and 1/2 and after you solve that solve 62/75- 0.16. Divided the first answer by the second. Now move to 3.5+4 and 2/3+ 2 and 2/15 then solve. Next solve 0.5 times ( 1 and 1/20+ 4.1) and with the answer you got from the equation above divided that by the answer just solved. Now divided the number on the left with the number on the right and you should get 4.

Step-by-step explanation:
The transformation that changes the area of a shape is dilation (Option D)
Step by step explanation
Option A: Translation
A translation is a geometric transformation that moves every point of a figure, shape, or space by the same distance in a given direction. For this type, the image is congruent with the original shape.
Option B: Rotation
A rotation is a type of transformation that takes each point in a figure and rotates it a certain number of degrees around a given point. For this type, the image is congruent with the original shape.
Option C: Reflection
A reflection is a transformation where each point in a shape appears at an equal distance on the opposite side of a given line - the line of reflection. For this type, the image is congruent with the original shape.
Option D: Dilations
Dilation in math is a transformation that changes the size of a figure so it becomes larger or smaller without changing shape. This type changes the area since the area is the size of a figure.
