Answer:
Solve the following equation
4x + 1 = 2x + 7
4x-2x=7-1
2x=6
X=6/2
X= 3
It is a whole number, and is positive
Answer:
a1) The model is a = 15/b
a2) When a = 10, b = 1.5
b) The polynomial function in standard form is
Step-by-step explanation:
a1) Since a and b varies inversely and a = 9, b = 5/3. First find the constant of proportionality.
The function that models the inverse variation is :
a = 15/b............(1)
a2) When a = 10, find b.
Substituting the value of a into equation (1)
10 = 15/b
b = 15/10
b = 1.5
b) Find the polynomial function with zeroes 1, 2, -2,3
The factors of the polynomials are x -1, x - 2, x + 2, x - 3.
The polynomial becomes:
