Let the first digit of the 2-digit number be x and the second digit be y.
Then the ratio (x/y) equals (1/2). Write a formula for y in terms of x.
The tens digit is 2 more than the units digit. Using the letters x and y, write out the proper equation.
Now solve your two equations simultaneously for x and y.
I've already been complemented twice on my previous answer, but then I discovered that I mis-read the question. My entire original answer was wrong, and I have to delete it.
I don't believe that any number can satisfy both of those conditions.
I'll say the question has no answer.
B. Banks want to know if it's risky or not to loan you money
The answer is C, because there are two different numbers correlated to the same number on the Y side. The table does not represent a function.
-7x<-93+86
-7x<-7
x>1 is the answer
DO YOU NEED TO GRAPH TOO?
