We are given equation 2x+3y=9xy.
A linear equation is a equation that has maximum degree of the equation as 1.
Degree is the maximum power(exponent) of the variables.
If two variables are being multiplied together in a term, we can find power of the that term by adding powers of those variables.
In the given equation, on the left side we have two terms 2x and 3y, each opf the variable x, and y has power 1 and right side of the eqaution we have term 9xy. There x and y variables are being multiplied together.
So, the total power of the term would be 1+1=2.
So, the degree of the given equation would be 2.
Because degree of the given equation is not 1. Therefore, given equation is not a linear eqaution and it is a non-linear equation.
Answer:
Step-by-step explanation:
The following ratio solves the problem
AM/MN = x / MP
(67.2 - 32) /67.2 = x / 81.9
35.2 / 67.2 = x / 81.9
Cross Multiply
67.2 * x = 81.9 * 35.2
67.2 x = 2882.88
Divide by 67.2
x = 2882.88 / 67.2
x = 42.9
You need 96 Square yards of carpet
The distance of sparky to the fire is 99.445 feet
<h3>
Application of SOH CAH TOA identity</h3>
Given the following parameters
The angle of depression = 6 degrees
If Sparky is looking over the fairly level, hence the hypotenuse is 100 foot
Required
Distance from spark tower to the fire
Using the expression below
Cos 6 = D/100
D = 100cos6
D = 100(0.9945)
D = 99.45foot
Hence the distance of sparky to the fire is 99.445 feet

Y=2x-9
therefore, slope is 2 and y-intercept is 9
