Answer:
I will assume the second equation is y=2x^3. If it is y=2x+3 or y=2x-3, the lines will never intersect: they have the same slope (2):
Step-by-step explanation:
2x – y = 7 can be rewritten as: y = 2x -7. It has a slope of 2. The second equation, y = 2x 3, isn't clearly written. If the 3 has a plus or minus sign, then the lines will never intersect: they have the same slope, 2.
I'll assume the second equation is y=2x^3.

Answer:
1. Linear
2. Nonlinear
3. Linear
4. Linear
5. Nonlinear
Step-by-step explanation:
Thies equation are in the form y=mx+b. Where m is the slope and b is the y-intercept. To solve them you neeed to see the power x is taken to. If the power on x is bigger than 1 than one, then it will curve at some point. This makes 2 and 5 nonlinear
Answer:
x > -39
Step-by-step explanation:
-0.3x < 6.7 + 5
-0.3x < 11.7
divide by -0.3
Answer is x > -39
They would be 20, 21, 22, 23, and 24
