Answer:
The correct option is B . (-1, 3)
The Point A is left of one unit Y -axis and above 3 unit X-axis, therefore the coordinates of point A is ( -1 , 3 ).
Step-by-step explanation:
Given:
Point A is on the Graph.
To Find:
coordinates of point A = ?
Solution:
Graph consist of X -axis and Y-axis
The intersection of X -axis and Y-axis is called as Origin.
Origin coordinate is ( 0 , 0 )
Coordinate is always given as ( x-coordinate , y-coordinate ) i.e ( x , y ).
So above X-axis y-coordinate is Positive, and below X-axis y-coordinate is Negative.
Similarly, Right of Y-axis x-coordinate is Positive, and Left of Y-axis x-coordinate is Negative.
The Point A is left of one unit Y -axis and above 3 unit X-axis, therefore the coordinates of point A is ( -1 , 3 ).
I also think the answer is "3".
|3x| = 9
|3x| = ±9
|3x| = 9 U |3x| = -9
3x = 9 U 3x = -9

x = 3 x = -3
|-3r| = 9
|-3r| = ±9
|-3r| = 9 U |-3r| = -9

The diameter of cylinder is 2.28 cm and area of wrapper is 60.56π cm².
<h3>What is Cylinder?</h3>
A cylinder is a three-dimensional solid figure which has two identical circular bases joined by a curved surface at a particular distance from the center which is the height of the cylinder.
Here, Given area of cylinder = 25π cm²
Height of cylinder = 11 cm.
Now, Area of Cylinder = 2πrh
25π = 2πr X 11
25 = 22r
r = 25 / 22
r = 1.14 cm
Then, diameter = 2r = 2 X 1.14 = 2.28 cm
Now area of wrapper = total surface area = 2πr(r + h)
= 2π X 2.28 (2.28 + 11)
= 4.56π X 13.28
= 60.56π cm²
Thus, the diameter of cylinder is 2.28 cm and area of wrapper is 60.56π cm².

Answer:
x=m-a/12
the m-a should be over 12 as the numerator but it's hard to type it like that
Step-by-step explanation:
a+12x=m
12x=m-a
x=m-a/12
