Let: eq 1:2x+5y=-55
eq 2:y=3x+6
by substituting eq 2 in eq 1 we get,
2x+5(3x+6)=-55
2x+15x+30+55=0
17x + 85=0
x=-85/17
x=-5
By substituting x value in eq 2,
we have,
y=3(-5)+6=-15+6=-9
ANSWER;
EXPLANATIONS;
Here, we want to get the probability of A, given B; where A refers to the event that the person surveyed is under 40, and B is the event that he or she gets the news by reading news paper
According to Bayes' theorem, we have the formula to use as;
Since the total is the same, we can work only with the numbers
So, firstly, we need the number of people that gets the news by reading news papers; we have this as 28
Now, we need the number of people who are under 40 and also gets their news by reading papers
We have this as 4
So, we have the probability as;
We have this as approximately 14%
Answer:
f(-3)=g(-4)

Answer:
The answer to your question is 20 ft squared
Step-by-step explanation: when you hear the word "side length", it means that whatever the side length is on one side, then this means that the other side lengths are gonna be the same side length as well. For example, we already know that a square garden has a side length of 5 ft. So, since we are trying to the find the area of the square garden, you can either multiply the side length of the square garden by 4, or you can add the side length of the square garden 4 times, which will look like this:
5ft*4ft=20ft2
or 5ft+5ft+5ft+5ft= 20ft2
The dependent variable depends on the value of the independent variable
normally it is something like
dependent variable=something times independent variable+something
it is normally the result or what the equation is
therefor the dependent variable is c (how much he has to pay total)
