This function shows a translation of a function f(x) = x, 2 units to the right and 4 units down.
<h3>Graphing modulus function</h3>
Modulus of a function are positive value of a function. Given the modulus expression as shown
f(x) = |x – 2| – 4
This function shows a translation of a function f(x) = x, 2 units to the right and 4 units down.
The resulting graph of the function is as shown below;

Height of the wall is 27 m.
<u>Explanation:</u>
Let the height of the wall = h
Length of the ladder = 9 m
Angle of elevation = 60°
Ladder rests at 9 m below a vertical wall.
So, length of the wall upto which the ladder rests = h - 9
We know,
Cos Ф = base/ hypotenuse
cos 60° = length of the ladder / height of wall upto which the ladder rests
So,
h - 9 = 18
h = 27
Therefore, height of the wall is 27 m
8x = 36 + 18y ⇒ -2(8x = 36 + 18y) ⇒ -16x = -72 - 36y
9x = 28 + 4y ⇒ 9(9x = 28 + 4y) ⇒ <u> 81x</u> = <u>252 + 36y</u>
65x = 180
x =
9x = 28 + 4y
9 = 28 + 4y
9(36) = 13(28 + 4y)
324 = 364 + 52y
-40 = 52y
Answer: x = , y =
