Considering the definition of zeros of a function, the zeros of the quadratic function f(x) = x² + 4x +9 do not exist.
<h3>Zeros of a function</h3>
The points where a polynomial function crosses the axis of the independent term (x) represent the so-called zeros of the function.
In summary, the roots or zeros of the quadratic function are those values of x for which the expression is equal to 0. Graphically, the roots correspond to the abscissa of the points where the parabola intersects the x-axis.
In a quadratic function that has the form:
f(x)= ax² + bx + c
the zeros or roots are calculated by:
<h3>This case</h3>
The quadratic function is f(x) = x² + 4x +9
Being:
the zeros or roots are calculated as:
and
If the content of the root is negative, the root will have no solution within the set of real numbers. Then 
has no solution.
Finally, the zeros of the quadratic function f(x) = x² + 4x +9 do not exist.

Answer:
the total cost of milk for Brand B will pass through the points (0,1.50) and (0.5,4.50).
Step-by-step explanation:
Brand A 2% milk costs $3.50 a gallon. If 0 gallons of milk are purchased, the cost is $0. If 1 gallon of milk is purchased, the cost is $3.50. So, the ray representing the total cost of milk for Brand A will pass through the points (0,0) and (1,3.50).
Brand B whole organic milk costs $3.00 for a half-gallon, plus a one-time deposit of $1.50 for the glass jug. At 0 gallons, the cost is $1.50 for the deposit. At 0.5 gallons, the cost is $3.00 + $1.50, or $4.50. So, the ray representing the total cost of milk for Brand B will pass through the points (0,1.50) and (0.5,4.50).
Since Brand A goes through the origin, Brand A is proportional. The correct graph is shown below.
Step-by-step explanation:
The answer of this question is -5 + 3x > 1
If my answer is wrong so I am really sorry for it
An equation shows the equal value of two expressions while an inequality shows that an expression is either less than or more than the other; an equation shows equality, inequality shows inequal
