Hi!
Your answer is Infinite.
Here's why:
When you solve this system of equations your final answer will come down to x=x.
When this happens you know that the solution amount is infinite!
I hope this helps!
Feel free to give brainliest of you think this answer deserves it!
I believe it’s 1/2 because 3/6 chances it’ll be a red marble. And 3/6 is also 1/2
The answer is 7*5*3*4=420
F(x) = x² + 4
y = x² + 4
First, I reverse the equation to be
x² + 4 = y
Second, we need only x to remain on the left side and we need to move the others to the right side
x² + 4 = y
x² = y - 4
x = √(y - 4)
Last, change into invers function
f⁻¹(x) = √(x - 4)
