Answer
Find out the how much did the height of the tree sapling increases.
To proof
Let us assume that the height of the tree sapling increases be x.
As given
The high every tree sapling was 3.15 inches last year
this year the high is 5.38 inches.
than the equation is become in the form
x = 5.38 - 3.15
x = 2.23 inches
Therefore the height of the tree sapling increases be 2.23 inches.
Hence proved
Use the distributive property to combine like terms. Since we only have one X value and one y value we need to use the 4. 2x times 4 is 4x. 3y times 4 is 6y. Now the equation can be simplified to 4x plus 6y. We have no more like terms so the equation cannot be simplified any further without more context.
Just from the figure,
As x decreases, y approaches 0
As x increases, y increases without bound
