ILL GIVE YOU BRAINLIST !! *have to get it right ! *
Marianna [84]

Answer:

-1/2

Step-by-step explanation:

Point L is at (-2,3)

Point M is at (2,1)

We can find the slope using

m =(y2-y1)/(x2-x1)

   = (1-3)/(2 - -2)

    =(1-3)/(2+2)

   =-2/4

  =-1/2

bogdanovich [222]
It Given the focus (h,k) and the directrix y=mx+b, the equation for a parabola is (y - mx - b)^2 / (m^2 +1) = (x - h)^2 + (y - k)^2.

The roots of a quadratic equation ax2+bx+c=0 are 3+sqrt2 and 3−sqrt2. Find the values of b and c assuming that a=1.
slamgirl [31]

Answer:

b=-6\\c=7

Step-by-step explanation:

we know that

The general equation of a quadratic function in factored form is equal to

y=a(x-x_1)(x-x_2)

where

a is a coefficient of the leading term

x_1 and x_2 are the roots

we have

a=1\\x_1=3+\sqrt{2}\\x_2=3-\sqrt{2}

substitute

y=(1)(x-(3+\sqrt{2}))(x-(3-\sqrt{2}))

Applying the distributive property convert to expanded form

y=x^2-x(3-\sqrt{2})-x(3+\sqrt{2})+(3+\sqrt{2})(3-\sqrt{2})

y=x^2-(3x-x\sqrt{2})-(3x+x\sqrt{2})+(9-2)

y=x^2-3x+x\sqrt{2}-3x-x\sqrt{2}+7

y=x^2-6x+7

therefore

b=-6\\c=7

postnew [5]

Answer:

(z+y)/6=x

Step-by-step explanation:

Solve for x: z=6x-y

Add y on both sides: z+y=6x

Divide by 6 on both sides (z+y)/6=x

Hope this helps plz mark brainliest if correct :D
