Lets make an equation for the line first. The slope is 3 and the y intercept is -1, so we can make the equation y = 3x - 1. Then, to figure out what sign to use (<= or >= due to solid line in graph), we replace the = sign with one and see if a coordinate in the shaded area will furfill the inequality. If it doesn't, we know it needs the other inequality sign. If it does, we have found the correct inequality. So let's try y <= 3x - 1 with the coordinate (1,1). We try it, solve, and get 1 <= 2. So, the inequality for this graph is y <= 3x - 1.

a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the r
Oxana [17]

Answer:

A. x²/y³

Step-by-step explanation:

Given the following data;

Length = x³y⁴

Width = xy^{7}

Ratio = length/width

Ratio = \frac{x^{3}y^{4}}{xy{^7}}

Simplifying the equation by applying the law of indices (division), we have;

\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2}

\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3}

Hence, rearranging the above values;

Ratio = \frac{x^{2}}{y^{3}}

<em>Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³. </em>
