Answer:
Step-by-step explanation:
Given the equation y=-2x+1 and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect. Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel. To have this result, we must have that they have the same slope but different y intercept. That is take m = -2 and b any value different to +1. For example, the b = 6. So
y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.
Answer:
3x+5
Step-by-step explanation:
Let number =X
So
Five more than 3 times a number
3x+5
Answer:
b is correct
Step-by-step explanation:
Well you'd see if it's closer to 10000 or 20000.
In this case it would round to 20000.
