Find the points on x-axis where the circle with equation X square + Y square - 8 x - 8 Y - 9 = 0

Mathematics

Mamont248 [21]3 years ago
4 0

Answer:

(- 1, 0) and (9, 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0 in the equation and solve for x, that is

x² + y² - 8x - 8y - 9 = 0

x² - 8x - 9 = 0 ← in standard form

(x - 9)(x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 9 =0 ⇒ x = 9

x + 1 = 0 ⇒ x = - 1

x- intercepts are (- 1, 0 ) and (9, 0 )

8_murik_8 [283]

Answer:


Step-by-step explanation: Use the two points that are given to you and substitute them into the slope formula to find the answer.

m=<u><em>y2-y1/x2-x1</em></u>

m=9-5/3-1

m=4/2

Simplify the answer.

m=4/2

m=2/1

Final answer is 2.

The slope is positive meaning it is ascending (going up).

<u><em>Hope this helps!</em></u>

Which property of polynomial addition says that the sum of two polynomials
ArbitrLikvidat [17]

Answer:

The property of polynomial addition that says that the sum of two polynomial is always a polynomial is called closure property of addition or under addition.

Polynomials are closed under addition because when you add polynomials the letters and their exponents do no change, you just add the coefficients of the like terms (those with same letters raised to the same exponents), so the result will be other polynomial of the same kind, except for the terms that cancel (positive with negative) which does not change the fact that the result is still a polynomial.

In mathematics the closure property means that the result of an operation over a kind of "number" will result in a "number" of the same kind.
