Y= x2 - 6x - 8 complete the square in the quadratic equation in order to write the equation in vertex form. a) y = (x - 3)2 + 1 b) y = (x + 3)2 + 1 c) y = (x - 3)2 - 17 d) y = (x + 3)2 - 17

Hello :

y  = x² - 6 x - 8

y = (x² -2(3)(x) + 9) - 9 - 8

y = ( x - 3)² - 17 ...(answer D )

Step-by-step explanation:

The answer is C)y = (x - 3)2 - 17. I took the usatestprep test.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
