Answer:
B. Undefined
Step-by-step explanation:
A function cannot have more than one x value with different y values. A vertical line means this happens infinite times. It is undefined.
Answer:
-2
Step-by-step explanation:
The slope of a line tells us how y responds to a change in x. If the slope is 2, it means that for every time x increases by 1, will will go up by 2.
We can calculate slope from a line, or with two given points. I used points (0,4) and (3,-2). Slope is the "Rise/Run."
The Rise: (-2 - 4) = -6
The Run: (3 - 0) = 3
Slope = Rise/Run = (-6/3) = -2
4 *3 = 12
12 * 20 = 240
240 / 2 = 120 units^3
answer is C
9c + 45 because you factor the 9 into both c and 5
