One number is 3 less than twice another. if their sum is 39, find the numbers.
which of the following systems of equations represents the word problem?
a. y = 2x - 3 and y = x + 39
b. y = 2x - 3 and x + y = 39
c. y = 2(x - 3) and x + y = 39

Let

y------> one number

x-----> another number

we know that

------> equation A

------> equation B

substitute equation A in equation B

Find the value of y

the numbers are and

therefore

the answer is the option B

and

question

what is the value of the third quartile of the data set represented by this box plot? a. 19 b. 21 c. 26 d. 29

answer

c

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
