Each equation will have it's own input/ output table, where you put in a value for y and get a value for x or put in a value for k and get a value for y For example : y = -7 + 3x Y | X _|____ 0 | 7/3. 1 | 8/3. -7 | 0. (unfortunatly the WikiAnswers cannot be formatted as I'd like but the above should be a table with Y valyues on the left and X values on the right) Now do the same for the other equation: y = 5x - 13 Y | X _|____ 0 | 13/5. 1 | 12/5. -13 | 0.
We want to know for what x will Fy(x) = 30. Let's look at what Fy does: There are 3 feet in a yard, so to get from yards to feet, Fy takes the input x, and multiplies it by 3: x (yards) * 3 (feet/yard) = 3*x feet Thus we want to solve 3x = 30 Divide both sides by 3: x = 10
-3x+4y doesn't have a maximum value because you can plug in anything for x and anything for y. In fact, if you keep x=0 and you plug in larger and larger numbers for y, you get a larger and larger output--it's unbounded.
There are an infinite number of lines that are all parallel to [ y = 3x + 6 ].Here are ten of them to get you started:y = 3x - 1y = 3xy = 3x + 1y = 3x + 2y = 3x + 3y = 3x + 4y = 3x + 5y = 3x + 5.99y = 3x + 6.001y = 3x + 7.etc.
It is an algebraic expression because it does not contain an equality sign.
