How can x^2=x^2+2x+9 be set up as a system of equations
Nikitich [7]

Answer: \left \{ {{y=x^{2} } \atop {y=x^2+2x+9}} \right.

Step-by-step explanation:

1. As you can see, x^{2} is equal to the other quadratic equation x^2+2x+9.

2. Then, this would the same as write the quadratic equations as following:

y=x^{2}

y=x^2+2x+9

3. And then set them equal to each other, as you can see below:

y=y

Substituting, you obtain:

x^{2}=x^2+2x+9

3. Keeping the above on mind, you can set up the given equations as a system of equations as folllowing:

\left \{ {{y=x^{2} } \atop {y=x^2+2x+9}} \right.

A) Necsito Ayudaa Con Eso<br />ayuden Porfa<br /-3x-7y=8 3x-2y=-44
STALIN [3.7K]
Hi! 

[1] -3x-7y=8
[2] 3x-2y=-44

lets take [1]
-3x-7y=8
-7y=8+3x
-7y-8=3x
3x=-7y-8

No use 3x=-7y-8 and put it in 3x-2y=-44
-7y-8-2y=-44
-9y-8=-44
-9y=-36
9y=36
y=4

then use y in 3x-2y=-44
3x-2(4)=-44
3x-8=-44
3x=-36
x=-12
Therefore, y = 4 and x = -12
