13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8
Do you need x as your answer or y
X= -2
25x+30= -22 -x
*subtract 30 from -22*
25x= -52
*divide 25 from each side*
x= -2
Answer:

Step-by-step explanation:
we know that
The volume of a pyramid is given by the formula

where
B is the area of the base
h is the height of the pyramid
we have

substitute the given values

Answer:part a :yes it is a linear function because it is a straighten lined Part b : LINEAR FUNCTION Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x. When x is 0, y is already 1. NONLINEAR FUNCTION An example of a nonlinear function is y = x^2. This is nonlinear because, although it is a polynomial, its highest exponent is 2, not 1.
