Well when you look at equations, they are all built from y=mx+b. Y and x are a point on that line, m is your slope, and b is the y intercept. So when you look at two equations, take the absolute value of m to find which is steeper. Take these two examples.
y=3x+4
y=-7x+4
Take the absolute value of 3 and -7
|3|=3
|-7|=7
7 is the larger number so y=-7x+4 has a steeper slope.
2^9=512
There are 512 possible solutions
Answer:
6 in
Step-by-step explanation:
The <em>area</em> of a picture <em>is</em> 25 7/5 square inches. If the width of the picture is 4 1/2 inches, what is the length? <em>(A=(w)(l) </em>)
Assuming that your "25 7/5 square inches" is not a mistake, then this is equivalent to 26 2/5 square inches.
Converting 26 2/5 sq. in. to an improper fraction, we get 132/5 sq. in., which represents the area of the picture. If the width is 4 1/2 inches, or 9/2 inches, then the length, l, is:
132/5 in^2
l = ------------------
9/2 in
To divide 132/5 in^2 by the fraction 9/2 in, invert 9/2 and multiply:
135 in^2 2
l = -------------- * ------ = 270/9 in = 30/5 in = 6 in
5 9
I would say that the answer is probably a screw and a lever.
