Answer:

20

Step-by-step explanation:

Make 12 into a fraction : 12/1

Then , using division with fractions , flip the 3/5 and multiply 12/1 and 5/3 .

The equation will look like this :

12/1 x 5/3

So 12 x 5 = 60 and 1 x 3 = 3 , making the fraction 60/3

That then simplifies to 20

Complete the square than convert to vertex form. y=2x^2+8x-9​
8_murik_8 [283]

y=2x^2+8x-9\\D=b^2-4ac\\D=64-4(2)(-9)\\D=64+72 > 0

There are 2 roots so the only way to complete the square is,

y=2x^2+8x-9\\y=2[(x^2+4x)]-9\\y=2[(x^2+4x+4)-4]-9\\y=2[(x+2)^2-4]-9\\y=2(x+2)^2-8-9\\y=2(x+2)^2-17

Just factor 2 out of 2x^2+8x (just ignore the -9) then find the number that will make the terms be able to complete the square.

then complete the square and multiply 2 inside the brackets.

subtraction as you already get the vertex form and know how to complete the square.

Vertex Form: y=2(x+2)^2-17

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16
Oksana_A [137]
To solve for the solution of this system of linear equation, it is best to use substitution. From the first equation, x = 3y

Substituting the expression on the right for the value of x on the second equation, 
 
                                    -2(3y) + 3y = 16

Solving for the value of y gives y = -5 1/3

With this value of y, solving for x gives x = -16

Thus, the solution for this system of linear equation is (-16, -5 1/3)
