Quadratic is where the degree of x is 2
I would think 3 is the one that might have been written as y=x² which would be correct

Answer:

x=-2.25,y=-2.25

Step-by-step explanation:

The given system is

$4x - y = - 9 \\ 3x - 3y = 0$

We want to solve the system for x and y that makes the system true.

Let us multiply the first equation by 3 while maintaining the second equation:

$12x -3 y = - 27 \\ 3x - 3y = 0$

Subtract the current second equation from the first one.

$12x = - 27$

Divide through by 12:

$x = - \frac{27}{12} = - 2.25$

From the second equation we have:

$3x = 3y$

This implies that:

$x = y = - 2.25$

12)<br> Which graph represents the solution for the equation-x-1=-x+ 2?

antiseptic1488 [7]

Answer:

Find the graph that has (2,0)

Step-by-step explanation:

$\frac{1}{2}x -1=-x+2$

+ x +x

$\frac{3}{2}x - 1 = 2$

$2(\frac{3}{2}x - 1 = 2)$

3x - 2 = 4

+ 2 + 2

3x = 6

/3 /3

x = 2

Your image is blurry, but the point that has (2,0)

Hope that helps!

What is the greatest common denominator of 81, 108, and 117?

stira [4]

If you mean greatest common factor then that means

factor each and group the ones that are same

81=3 times 3 times 3 times 3
108=2 times 2 times 3 times 3 times 3
117=3 times 3 times 13
so we look for the group common to all (I bolded it)

81=3 times 3 times 3 times 3
108=2 times 2 times 3 times 3 times 3
117=3 times 3 times 13
the answeis 3 times 3=9

greates common denomenator of these nubers is 9
