3x - 2 = x + 10
So, 2x = 12 and x = 6
Answer:
The domain for graph 1 is all real numbers, the range is y >= 0.
The domain for graph 2 is x >= 0, the range is y >= 0
Step-by-step explanation:
Graph 1: The x values are infinite for the graph, the y values will always be above zero and continue to be infinite.
Graph 2: The x values start at 0 and go to the right for infinity, the y values start at 0 and continue to infinity.
The ratio given is 4:5 so you do 5divided by 20 which is 4 and multiply 4 and 4 and get 16 so your ratio is 16:20
