Answer:
C
Step-by-step explanation:
The value is -21. Which you get by multiplying -7 and 3 together.
Both graphs A and B are linear. In both graphs, the y value is going up at a constant rate in comparison to their x values. For example, in graph A every time the x value is increased by 1 the y value is increased by 2 values showing that they have the same gradient. For a graph to be linear it must have a constant rate of increase or decrease.
Answer:
x=39/2
Step-by-step explanation:
2x-3=36
