Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16

pishuonlain [190]

$y = - 3(x - 2) ^{2} + 4$
$y = - 6x + 16$
distribute the -3 and the square into the first equation
$y = - 3x ^{2} + 12x - 8$
$y = - 6x + 16$
multiply the second equation by 2
$y = - 3x ^{2} + 12x - 8$
$y = - 12x + 32$
add the equations together
$y = - 3x ^{2} + 24$
factor out -3
$y = - 3(x ^{2} - 8)$
factor inside parenthesis
$y = - 3(x + \sqrt{8} )( x - \sqrt{8})$
refine
$y = - 3(x + 2 \sqrt{2} )(x - 2 \sqrt{2} )$

Add the followinf expresion<br>b. x- 3y + 4z , y – 2x- 8z ,5x – 2y – 3z

Mariana [72]

Answer:

4x - 4y - 7z

Step-by-step explanation:

x - 3y + 4z + y - 2x - 8z + 5x - 2y - 3z =

(x - 2x + 5x) + (y - 3y - 2y) + (4z - 8z - 3z) =

4x + (- 4y) + (-7z) =

4x - 4y - 7z <===

Choose the point-slope form of the equation below that

PilotLPTM [1.2K]

Answer:

A) y-4=-1/2(x+6)

Step-by-step explanation:

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

m=(0-4)/(2-(-6))

m=-4/(2+6)

m=-4/8

simplify

m=-1/2

y-y1=m(x-x1)

y-4=-1/2(x-(-6))

y-4=-1/2(x+6)
