Answer: Sometimes
Step-by-step explanation:
A system of equations can intersect at no points; this is when the lines are parallel, which means they have the same slope and different y-intercept.
A system of equations can intersect at one point; this is when the lines have different slopes.
A system of equations can intersect in infinitely many points; this is when the graphs overlay one another, which means they are graphs of the same line. The two equations would equal the same thing.
No picture, nothing to rate here.
Is that the top or bottom? Assuming it's the top, when distributing the -2 to what's inside the parenthesis, they were correct in multiplying -2•7, but when they multiplied -2 and -y, the answer needs to be positive 2y because they are multiplying double negatives
You can divide 1/2 by 1/4
that'll leave you with 1/8, which is smaller than 1/4
5 or less books can fit, so...
5<x with the line the line under the sign.
