To find the inequality, we need to remember our rules about what makes inequalities from number lines.
If the "dot" (initial point) is hollow, it is simply a "<" or ">" symbol. If the "dot" is filled in, it means that it includes that number and we should use a "≤" or "≥" symbol. In this case, our "dot" is filled, so we will be using a "≤" or "≥" symbol.
The second rule we must recall is that the "arrow" (symbol) points the direction that the line will go. In this case, our line is going left, so our "arrow" should point left (≤).
Using all of the logic above, we would be able to see that x≤1.
The domain of this function is x = all real numbers.
The range of this function is that y ≥ 0.
To find the domain, you need to look for exclusions. The only numbers that you exclude are when you can't divide by 0 or have a negative square root. Since this problem has no square root symbol or fractions, it is all real numbers.
For the range, we need to find the smallest value of y. y can get no smaller in this problem than when x = 0. In that case y also = 0. Because the lead coefficient is positive (4), we know that the graph is increasing. Therefore, we know that y must always be bigger than 0.
The perimeter (IP) of a rectangle is
P = 2(length + width)
let width = w then length = w + 88
P = 2(w+w+88) = 2(2w+88) = 4w+176
Thus P = 4w+176 = 7272
hence 4w = 7272 - 176 = 7096
so w = 7096/4 = 1774
width = 1774 inches and length = w+88 = 1774+88 = 1862 inches
