To represent the solution set of a linear equation parametrically, we introduce other parameters like s and t for the free variables.
Every linear equation has n - 1 free variables where n is the number of variables.
For x + y + z = 2, we have 3 variables and 3 - 1 = 2 free variables.
First, let y and z be the free variables, we first solve the linear equation for x to get:
x = 2 - y - z
Therefore , the parametric representation of the solution set is given by :
x = 2 - s -t
y = s
z = t

Hello,
The method is to find the roots of the denominator.
x²-2x-15=x²+3x-5x-15=x(x+3)-5(x+3)=(x+3)(x-5)
Roots are x=-3 and x=5
Answer C
Answer:
66. Assuming after you substituted 3 in place of x, you followed order of operations, or PEMDAS.
Step-by-step explanation:
6(2x) + 9x +3 = area
6 (2(3)) + 9(3) + 3 = area
6 x 6 + 27 + 3 = area
36 + 30 = 66
area = 66
Answer:
order
500x+38000
500(22)+38000
11000+38000
49000
Step-by-step explanation:
We can write the following equation
38000+500x= salary
where x is the number of air conditioners sold
To get the answer just plug in 22 for x
38000+500(22)=49000
