Find the coordinates of d if e (-6,4) Is the midpoint of df and f has coordinates (-5,-3)
Oksanka [162]

Answer:

Step-by-step explanation:

Let the coordinates of d be (x,y)

The midpoint of (x,y) and (-5,-3) is equal to ((-5+x)/2, (-3+y)/2)

this should be equal to the coordinates of e, (-6,4)

we have (-5/2+x/2, -3/2+y/2)

-5/2+x/2 = -6

-5 + x = -12

x = -7

-3/2+y/2 = 4

-3+y = 8

y = 11

Therefore the coordinates of d are (-7,11)

I am Lyosha [343]

Answer:

The answer is yes because no value of x repeats remember a function is for every value of x is exactly one output for y so if you input the same value of x and you get two different values then it's not a function

Is this equation standard form of an ellipse or circle?
Usimov [2.4K]
The standard form equation for a circle is

(h-x)^2+(k-y)^2=r^2

where (h, k) is the center and r is the radius.

The standard form equation for an ellipse is

\frac{(x-h)^2}{a^2}} + \frac{(y-k)^2}{b^2} = 1

(center h, k and major and minor axes a and b)

This equation is standard form for neither, but might be general form for one.

-3x^2-3y^2-12x-12y+24=0 \\ -3(x^2+y^2+4x+4y)=-24 \\ x^2+4x+y^2+4y=8\ (complete\ the\ squares)\\ (x^2+4x+4)+(y^2+4y+4)=8+4+4\\ (x+2)^2+(y+2)^2=16 \\ Circle\ with\ radius\ 4\ and\ center\ (2,\ 2)
