Do you need the answer now ?
3x>=8
It should be
Three is less than or equal to eight
B, the lowest because would you rather pay 12% daily or monthly
let's recall that perpendicular lines have negative reciprocal slopes, so say for a line with a slope of a/b

a perpendicular one will be -b/a.
what does that mean? well, that the lines are perpendicular of course, they meet at a 90° angle, and two straight lines meeting at 90° can only meet once.
since a solution to a system of equations is where the graph meet, and these two meet perpendicularly once, then that means only one solution.
Answer: 4 roots
Step-by-step explanation: Just look at the highest power and that will tell you the amount of roots, unless there are imaginary roots
