Answer:
-4
Step-by-step explanation:
I know the parabola will open downward because the leading coefficient of the equation, being -5, is negative/less than zero.
We have been given that red, green, and white jellybeans are combined in a ratio of 5:4:3 respectively. We are asked to find out the ratio of green jelly beans to the total number of jelly beans.
In order to find out the ratio of green jelly beans to the total number of jelly beans we have to find out the total number of jelly beans.

Now we can find out out our desirable ratio by substituting our finding in the ratio.

Therefore, ratio of green jelly beans with respect to all jelly beans is 1:3.
I hope this helps you
(f (x))^2= (square root of x-2)^2
f^2 (x)=x-2
x=f^2 (x)+2
f^-1 (x)=x^2+2
The answer is the option A, which is: A. x-7=x²+2x-4
The explanation is shown below:
To solve this problem you must apply the proccedure shown below:
1. You have the following system equations given in the problem above:
<span>y=x-7
y=x²+2x-4
2. Therefore, when you substitute for y in the bottom equation, you obtain:
</span>x-7=x²+2x-4
