Which table contains the vertex of the graph represented by y=x^2-6x+4?
Vaselesa [24]

vertex = (3,- 5 )

given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then

the x-coordinate of the vertex is

x_{vertex} = - \frac{b}{2a}

y = x² - 6x + 4 is in standard form

with a = 1, b = - 6 and c = 4, hence

x_{vertex} = - \frac{-6}{2} = 3

substitute this value into the equation for y- coordinate

y = 3² - 6(3) + 4 = 9 - 18 + 4 = - 5

vertex = (3, - 5 ) → second table

what is the equation of a line that passes through the point (6,1) and is perpendicular to the line whose equation is y=2x-6?
alexandr402 [8]

Answer:

y = -(1/2)x + 4

Step-by-step explanation:

Use the standard form on an equation:  y = mx + b

A line that is perpendicular has a slope that is the opposite reciprocal of the other line.  We also have a point (x, y) that is on the line, so our equation begins as..

1 = -(1/2)(6) + b           We must solve for b (  -1/2 is the opposite reciprocal of 2)

1 = -3 + b

4 = b  

so our equation is

y = -(1/2)x + 4

Find the length of the third side. If necessary, write in simplest radical<br> form.<br> 8<br> 17
statuscvo [17]

Answer:

9

Step-by-step explanation:

so we know that its a right triangle and 8 and \sqrt{17} are not the hypotenuse.

the equation for this is a^{2}+b^{2}=c^{2} with c being the hypotenuse.

8^{2}+\sqrt{17} ^{2}=c^{2}

64+17=c^{2}

81=c

\sqrt{81}=c

9=c
