Answer:
The result after adding a set of numbers or is called a sum.
Step-by-step explanation:
Consider the provided information.
The four mathematical operations are:

The sign + is used to add numbers.
The sign - is used to subtract the numbers.
The sign × is used for the product of the numbers.
The sign ÷ is used for division of the numbers.
When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.
For example:
Consider the number: 2 + 5 if we add the number the resulting value will be 7.
The number 7 is the sum of 2 and 5.
Thus, the result after adding a set of numbers is called a sum.
B.
You can get this by using the quadratic equation, which I listed below.

With a = 2, b = 1, c = -45
Answer:
1/2
Step-by-step explanation:
I will assume you would like the line
slope = (y2-y1)/ (x2-x1)
m = (4-0)/(9-5) = 4/4 = 1
equation of a line in point slope form is
y-y1 = m (x-x1)
y-0 = 1 (x-5)
y=x-5
