Answer:
n=4
Step-by-step explanation:
To get an undefined slope, the denominator has to be zero
m= (y2-y1)/ (x2-x1)
This means that x2-x1 = 0
or x2=x1
So 4=n
40:260 is the ratio for this problem
Answer:
Step-by-step explanation:
hello :
a(x) = 3x - 12 and b(x) = x-9, so
a[b(x)]=a(x-9) =3(x-9)-12
a[b(x)]=3x-9-12
a[b(x)]=3x+21
Answer:
Polynomials are algebraic expressions that consist of variables and coefficients. ... We can perform arithmetic operations such as addition, subtraction, multiplication and also positive integer exponents for polynomial expressions but not division by variable. An example of a polynomial with one variable is x2+x-12.
