For this case we have a factorized quadratic equation. We equal each factor to zero and thus find the roots:

Subtracting 5 from both sides we have:

Thus, the first solution of the equation is:

On the other hand we have:

Adding 3 to both sides:

Thus, the second solution of the equation is:

Answer:
The solutions of the equation are:

Answer:
11th floor
Step-by-step explanation:
So to figure out what floor Rosa's office is in, we need to declare some variables.
x = Rosa's office
down 5 floors = -5
up 8 floors = 8
down 13 floors = - 13
One major clue to find Rosa's office is that she went down 13 floors to get to the 1st floor. So let's declare that Rosa is on the first floor.
x - 5 + 8 - 13 = 1
x - 10 = 1
x = 1 + 10
x = 11
So Rosa's office is at the 11th floor of the building.
Answer: if you have infinity points, which i will asume are the events, they cant have the same probability because then the probability will not be normalized, because in graph of prob vs variable, you will se infinite area under the curve if the probability is constant.
And yes, can all points have positive probability of occurring, but besides you medium value (the bell for example) you will see an asintotic decrease to the zero.
Answer:
y = -x+3
Step-by-step explanation:
We have two points so we can find the slope
m =(y2-y1)/(x2-x1)
(1-2)/(2-1)
-1/1
The slope is -1
We can use the slope intercept form of the equation
y = mx+b where m is the slope and b is the y intercept
y = -x+b
Substitute a point into the equation to find b
2 = -1 +b
Add 1 to each side
2+1 =-1+1 +b
3 =b
y = -x+3
