Answer:
like segment BC is parallel to AD
It is not linear.
In a linear equation, you cannot divide by a variable.
Here you are dividing by x, so the equation is not linear.
Answer:
![2x^2y[x^{2}y^{2}-6xy-4]](https://tex.z-dn.net/?f=2x%5E2y%5Bx%5E%7B2%7Dy%5E%7B2%7D-6xy-4%5D)
Step-by-step explanation:
we have

so
Answer: The answer is -19.
Step-by-step explanation: We are given to write the numerical coefficient of -9x.
The given expression is a monomial with unknown variable 'x'.
We know that a numerical coefficient of a monomial is a constant multiplied to the variable(s). For example, in the term -5xy, the unknown variables are 'x' and 'y' and the numerical coefficient is -5.
Therefore, in -9x, the unknown variable is 'x' and the numerical coefficient is -9.
Thus, the answer is -9.
8 * 9 = (5 + y) * 9
multiply 8 and 9
72 = (5 + y) * 9
use the distributive property
72 = 45 + 9y
subtract 45 from both sides
27 = 9y
divide both sides by 9 to isolate the variable
y = 3
