A function is a relation where each input value is assigned to exactly one output value.<span>
The domain of a function is the set of all input values, or x-values, for which the function is defined.
The range of a function is the set of all output values, or y-values, for which the function is defined.
To write the equation y = ax + b in function notation, f(x) substitute for y.</span><span>

5/20=x/28 therefor x equals 7 and since the triangles are similar to each other so y =120
Answer:
$14.07
Step-by-step explanation:
100 - 15 = 85
You change this into a multiplier 0.85.
18 x 0.85 = 15.30
100 - 8 = 0.92
0.92 x 15.30 = 14.07
The expression can be used to show the length of one side of the triangle is 4x+6.
Given
An equilateral triangle has a perimeter of 12 x + 18 units.
<h3>What is the perimeter of an equilateral triangle?</h3>
The perimeter of the Equilateral Triangle is simply the sum of its three sides which are equal in length. Perimeter is denoted by the P symbol.
![\rm Perimeter= 3 \times S](https://tex.z-dn.net/?f=%5Crm%20Perimeter%3D%203%20%5Ctimes%20S)
Therefore,
The expression that can be used to show the length of one side of the triangle is;
![\rm Perimeter = 12x+18\\\\Perimeter = 3(4x+6)](https://tex.z-dn.net/?f=%5Crm%20Perimeter%20%3D%2012x%2B18%5C%5C%5C%5CPerimeter%20%3D%203%284x%2B6%29)
Hence, the expression can be used to show the length of one side of the triangle is 4x+6.
