Find the slope of the line. -7 , - 1/7, 7, 7/1

frutty [35]

Slope = (y₂-y₁)/(x₂-x₁)
by making (x₁,y₁) = (-2,2) and (x₂,y₂) = (5,3)
∴The slope = (3-2)/(5 - -2) = 1/7

In 20 seconds, a roller coaster goes up a 100-meter hill, then down 72 meters, and then back up a 48-meter rise. What integer re

Finger [1]

The question is an illustration of arithmetic operations.

The integer that represents the vertical rise is 76

<em>Upward movements are represented with positive, while downward movements are represented with negative.</em>

<em />

So, the given parameters are:

$Up = 100m$

$Down = -72m$

$Up= 48m$

The vertical rise is:

$Rise = Up_1 + Down + Up_2$

So, we have:

$Rise = 100m -72m +48m$

$Rise = 76m$

Hence, the integer that represents the vertical rise is 76

Let f be defined as shown on the graph. Which statement is true?

satela [25.4K]

The inverse of f does NOT exist. The reason why is because the function fails the horizontal line test. Recall that the horizontal line test is a test where you try to see if you can pass a single horizontal line through more than one point on the function curve. If you can get the horizontal line to pass through more than one point, then it fails the test. It's very similar to the vertical line test.
