Answer:The equation x² + 7 = 0 has no solution
Explanation:1- using graph:To solve the equation means graphically means to find the x-intercepts.
The attached image shows the graph of the given function.
We can note that there are no x-intercepts. This means that the given function has no real solutions
2- using algebra:To solve the equation algebraically means to find the values of x that would make the equation equal to zero.
Solving the given equation, we would find that:
x² + 7 = 0
x² = -7
x = <span>± </span>√-7
The square root of a negative number will always give imaginary values. This means that the equation has no real solutions
Hope this helps :)
Hello,
Let's x² the square number
and 3*y the multiple of 3.

2 solutions : for (x,y) as integers : (-6,18) and (6,18)
but one solution for (x²,3y) as integers :<u> (36,54) </u>

Answer:
(5,2)
Step-by-step explanation:
You have to look to the X axis and you'll see the smiley face 5 bars/lines across from the vertex or 0.
Next, you'll need to look at the Y axis and see that the smiley face is 2 bars/lines vertically from 0.
So all you need to do is put the numbers into (x,y) and you'll get (5,2)
Hope this helps!
