Answer:

For every 1 inch on the drawing, it's 3 feet in real life.

Step-by-step explanation:

First, consider the length. The length is 6 inches on the drawing, while in actuality it is 18 feet. So every 6 inches represents 18 feet. Let's make a ratio; 6 : 18. To simplify it, divide both sides by 6; 6 : 18 = 1 : 3.

For every 1 inch on the drawing, it's 3 feet in real life.

Express the area of the rectangle in term of x

aalyn [17]

Answer:

Area = $12-\frac{4}{35}x$

Step-by-step explanation:

Length of the given rectangle 'l' = (15 - $\frac{1}{7}x$ )

Width of the given rectangle 'w' = $\frac{4}{5}$

Area of the rectangle = lw

= $\frac{4}{5}(15-\frac{1}{7}x)$

= $\frac{4\times 15}{5}-\frac{4}{5}\times \frac{1}{7}x$

= $12-\frac{4}{35}x$

Therefore, expression that defines the area of the given rectangle will be,

Area = $12-\frac{4}{35}x$

Determine the horizontal, vertical, and slant asymptotes: y=x2+2x-3/x-7

densk [106]

Answer:

vertical asymptote: x = 7
slant asymptote: y = x+9

Step-by-step explanation:

The vertical asymptotes are found where a denominator factor is zero (and there is no corresponding numerator factor to cancel it). Here, that is at x = 7.

There is no horizontal asymptote because the numerator is of higher degree than the denominator.

When you divide the numerator by the denominator, you get ...

y = (x +9) +60/(x -7)

Then when x gets large, the behavior is governed by the terms not having a denominator: y = x +9. This is the equation of the slant asymptote.
