Hello!
First of all we need to find what y equals to have it in slope intercept form.
y-x=5
y=x+5
As you can see, our slope has to be one, and our y-intercept is 5.
y=x+5
I hope this helps!

Answer:

If we find the individual probabilities we gotL

And replacing we got:
![P(X \geq 3) = 1- [0.0068 +0.0494 +0.1543]= 0.7895](https://tex.z-dn.net/?f=P%28X%20%5Cgeq%203%29%20%3D%201-%20%5B0.0068%20%2B0.0494%20%2B0.1543%5D%3D%200.7895)

Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
For this case we want to find this probability:

And we can use the complement rule for this case:

If we find the individual probabilities we gotL

And replacing we got:
![P(X \geq 3) = 1- [0.0068 +0.0494 +0.1543]= 0.7895](https://tex.z-dn.net/?f=P%28X%20%5Cgeq%203%29%20%3D%201-%20%5B0.0068%20%2B0.0494%20%2B0.1543%5D%3D%200.7895)
Turn the percentage into a decimal by sliding the decimal twice from the right to the left and multiply it to the number
add/subtract it depending on if it's increasing or decreasing
Answer:
see below
Step-by-step explanation:
f(x)= -(x-2)^2 +4
This is the vertex form of the equation for a parabola
y= a ( x-h)^2 +k where (x,k) is the vertex of the parabola
a = -1 h= 2 k = 4
The vertex is ( 2,4)
