Answer:

x = -3

Step-by-step explanation:

x - 9 = 4x

-3 - 9 = 4(-3)

|-12| $\neq$ -12

Inessa05 [86]

Answer:

a. y(t) = 0

Step-by-step explanation:

There are two axis on the graph. One is x-axis which is horizontal line on the graph and the other is y-axis which is vertical side of the graph. The point where x-axis and y-axis meet is origin which has value 0. The equation to write the points of the graph is represented by y(x) = 0. In the given equation there is t variable used in the values.
