Help i dont remember dis stuff from last year
1 answer:
See below for the solution to the systems of equations
<h3>How to solve the systems of equations?</h3><u>System of equations 1</u>
Here, we have
3x - 4y = -16
3x + 4y = 8
We start by plotting the graph of both equations
Next, we write out the point of intersection of the equations
See attachment for the equation of the system
From the attached graph, the point of intersection of the equations is (-4/3, 3)
Hence, the solution to the system is (-4/3, 3)
<u>System of equations 2</u>
Here, we have
-x = - 6 + 2y
-18 + 6y = -3x
We start by plotting the graph of both equations
Next, we write out the point of intersection of the equations
See attachment for the equation of the system
From the attached graph, both lines are on each other
This means that the system of equations have infinite many solutions

Answer:
Step-by-step explanation:
It is given that The probability a person is infected by a certain cold virus is 0.2 that is p=0.2, then q=1-0.2=0.8.
Now, we have to find the probability that at least one person will be affected by the cold virus, that is P(x>1).
P(x>1)=1-(P(x=0)+P(x=1))
=
=
=
=
=
=
=
=
Thus, probability that at least one person will be affected by the cold virus will be=0.726.
Hello.
Firstly, let's isolate x on the equation:
Now, we can replace 'x' for 'y' and vice-versa:
Hope I helped.
