Answer: D. Subtracting 9 from each side
Step-by-step explanation:
Always start with numbers without variables first before doing anything with x. And make sure one side must not equal 0 unless you're doing polynomials.
All of them are true except AD = GH.
Answer:
x=2;y=2
Step-by-step explanation:
2x+y=6..........1
3x-y=4............2
adding equation1 with equation 2
2x+y+3x-y=6+4
5x=10
x=10/5=2
substituting vslue of y in equation 1
2×2+y=6
y=6-4
y=2
How many times does 4 go into 37?
Well, 4*9 is 36.
37 and 36 have a difference of 1. You take that one and put it over the 4.
Therefore, 37/4 into a mixed number is 9 and 1/4
Answer:

Step-by-step explanation:
Rewrite the given polynomial in the form ax² + bx + c:

To find the zeros, set the function to zero and solve for x using the quadratic formula.

<u>Quadratic formula</u>:

Therefore,
Substituting the values into the quadratic formula:






The sum of the roots of a polynomial is -b/a:

The sum of the found roots is:

Hence proving the sum of the roots is -b/a
The product of the roots of a polynomial is: c/a

The product of the found roots is:

Hence proving the product of the roots is c/a
Therefore, the relationship between the roots and the coefficients is verified.
