Step-by-step explanation:
If y was directly proportional to x, the graph of y against x would pass through the origin (O).
Since the graph above does not show this, y is not directly proportional to x.
Answer:
The correct option is C. 126 in²
Step-by-step explanation:
Diameter of the container = 5 inches
⇒ radius of the container = 2.5 inches
Height of the container = 8 inches
To find how much paper is needed to create the label : We need to find the lateral surface area of the cylindrical shaped container
Lateral Surface Area of Cylinder = 2·π × radius × height
= 2 × 3.14 × 2.5 × 8
= 125.66 square inches
≈ 126 square inches
Hence, 126 square inches of paper is needed to create the label.
So, The correct option is C. 126 in²
Answer: <em>The values of......</em>
<em>
</em>
Step-by-step explanation:
Given function is: 
For 
the value of 
is -5, which is not equal to -2.
So, 
For 
the value of is -2.
So, 
For 
the value of is 4, which is not equal to -2.
So, 
Answer: Length = 28cm
Width = 7cm
Step-by-step explanation:
Let the width be represented by x.
Since the length is four times its width. Therefore, the length would be:
= 4 × x = 4x
The perimeter of a rectangle is calculated as:
= 2(length + breadth)
Therefore, 2(4x + x) = 70
2(5x) = 70
10x = 70
x = 70/10
x = 7
Therefore, width = 7cm
Length = 4x = 4 × 7 = 28cm
