The vertex of this parabola is at (-3, 6). Which of the following could be its equation?

12345 [234]

Nice, already in vertex form
y=a(x-h)^2+k
(h,k) is vertex

therfor since (-3,6) is vertex
we are looking for something like
y=a(x-(-3))^2+6 simplified to
y=a(x+3)^2+6

A is ansre

A complete table with values for x or y that make this equation true:3x+y=15

Andreyy89

Answer:

Step-by-step explanation:

The given equation is: $3x+y=15$ ,

Now, putting x=2 in above equation,

$3(2)+y=15$

$y=15-6=9$

Now, put y=3 in the given equation,

$3x+3=15$

$3x=12$

$x=4$

Putting x=6,

$3(6)+y=15$

$y=15-18$ $y=-3$

Putting x=0,

$0+y=15$

$y=15$

Putting x=3,

$3(3)+y=15$

$y=15-9$

$y=6$

Putting y=0,

$3x+0=15$

$x=5$

Putting y=8,

$3x+8=15$

$3x=7$

$x=\frac{7}{3}$

M is the midpoint of AB and C is the midpoint of AM . Let the coordinate of A = 7y and the coordinate of B = 3x. Find the coordi

xz_007 [3.2K]

Answer:

The answer is below

Step-by-step explanation:

The coordinate of the midpoint of a line is gotten by adding the values of the two end points and then dividing the result by 2.

Given that M is the midpoint of AB, A = 7y and B = 3x, hence the coordinate of point M is given as:

M = (A + B)/2 = (7y + 3x)/2

Also, C is the midpoint of AM, hence the coordinates of point C is given as:

$C=\frac{A+M}{2}\\ \\C=\frac{7y+\frac{3x+7y}{2} }{2}\\ \\C=\frac{\frac{14y+3x+7y}{2} }{2}\\ \\C=\frac{21y+3x }{4}$

Hence the coordinates for point C is $C=\frac{21y+3x }{4}$
