Answer:
(5,4)
Step-by-step explanation:
midpoint = (6 + 4 / 2 , 3 +5 / 2)
= (5,4)
The answer is 15 percent.
5290-4600=690
690/4600=0.15
Covert the 0.15 into percent which is 15 percent
Answer:
x = -3, 
Step-by-step explanation:
The given quadratic equation is: 
This can be written as: 
To solve a quadratic equation of the form
we use the formula:

Here, a = 2; b = 3; c = - 9
Therefore, the roots of the equation are:



We get two values of 'x', viz.,
x =
and 

⇒ x = -3, 3/2
Since the factors of the quadratic equation is asked, we write it as:
(x + 3)(x -
) = 0
because, if (x - a)(x - b) are the factors of a quadratic equation, then 'a' and 'b' are its roots.
Multiply (x + 3) and (x -
to see that this indeed is the given quadratic equation.
