It's 11040 plants because 92 percent of 12000 is 11040. (Idk if this is the best reasoning but :/)
(-10= xy + z ) (-z)
(-10-z = xy ) (1/y)
-10/y - z/y = x
x = -(10+z)/y
To be a function, a graphed equation must pass the vertical line test, i.e. a vertical line must not pass through more than one point on the graph, or the equation must not have more than one y-value for each x-value. All but the lower-left graph fail this test, and are therefore not functions.
60%
40 ÷ 10 = 4
24 ÷ 4 = 6
6 = 6/10 = 3/5 = 0.6 = 60%
Your answers will be A, B and D
