Answer:

The value of x is 1 and y = -2

Step-by-step explanation:

y = 2x²- 3x - 1;

y = x - 3

2x²- 3x - 1 = x - 3

2x² - 3x - 1 - x + 3 = 0

2x² - 4x + 2 = 0

take 2 as common

2(x² - 2x + 1) = 0

x² - 2x + 1 = 0

x² - x - x + 1 = 0

x(x - 1) - 1(x - 1) = 0

(x - 1) (x - 1) = 0

x - 1 = 0 or x - 1 = 0

x = 1 or x = 1

Now,

y = x - 3

y = 1 - 3

y = - 2

Thus, The value of x is 1 and y is -2

What is the answer when subtracting (-3y2-8)-(5y2+1)?

Alona [7]

You have to distribute the minus sign to the second parenthesis, changing the sign of every term:

$-3y^2-8-(5y^2+1) = -3y^2-8-5y^2-1 = -8y^2-9$

Describe the relationship of the segments made when chords intersect inside a circle. Use the following image as reference.

slavikrds [6]

There is a theorem that said that the ratio of lengths of chords at point of intersection are the same.
I think the relationship would be X/W = Y/Z

hope this helps

PLEASE ANSWER I WILL MARK THE BRAINIEST ANSWER :) factorise: X^2 + 10x + 16

Damm [24]

Answer:

(x+2)(x+8)

Step-by-step explanation:

1.)find factors of the third expression(16)that will add up to give the second expression(10)

16=2×8. 10=2+8

2.)substitute those factors inplace of 10

${x}^{2} + 10x + 16$

$x {}^{2} + 2x + 8x + 16$

3.)factorise using grouping method

$( {x}^{2} + 2x) + (8x + 16)$

$x(x + 2) + 8(x + 2)$

$= (x + 2)(x + 8)$
