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} )

Answer:

t = 4

Step-by-step explanation:

you have -8 and twelve you equation is x -12 = -8 so we just have to flip the equation around to make it x = 12 -8 which is easy . You just have to make sure you don't get mixed up while flipping the signs.

Pls help, I don’t understand how to do this
MAVERICK [17]

Answer:

5 parts are shaded and 4 parts are white so:

There are 9 parts all together.

We can then form ratio's of the white areas and the shaded areas:

White Area Ratio =

\frac{4}{9}

Shaded Area Ratio =

\frac{5}{9}

Let the area of sqaure be equated to x, which means let the entire area of the square equal to x:

x = Area of whole square

Now we can form an equation :

\frac{5}{9} x = 165

So now we just need to solve for x:

x = \frac{165}{ \frac{5}{9} }

x = 297

The area of the square is:

297 {cm}^{2}
