The sum of the digits of a two digit number is 14. The difference between the tens digit and the units digit is 2. If x is the tens digit and y is the ones digit, which system of equations represents the word problem?
Oxy = 14 and x - y = 2
Ox+y = 14 and x - y = 2
x + y = 14 and y - x = 2

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
