Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.
subtracting 3x2 + 4x – 5 from 7x2 + x + 9 results in a polynomial. after subtracting 4x2 – 3x from this polynomial, the difference is

14

Step-by-step explanation:

Please be certain to use " ^ " to denote exponentiation:

3x^2 + 4x – 5, 7x^2 + x + 9, 4x^2 - 3x

First, perform this subtraction:

 7x2 + x + 9

-(3x2 + 4x – 5)

 4x^2 - 3x + 14

Next, subtract 4x^2 - 3x from the above result:

 4x^2 - 3x + 14

-(4x^2 - 3x)

                    14 (answer)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
