4-4 Parallel and Perpendicular Lines
There are no like terms to be combined. The expression is already simplified.
3(x + 2x)
At a Farmers Market, merchants can rent a small table for $5.00 and a large table for
$8.50. One time, 25 small and 10 large tables were rented. Another time, 35 small and 12 large were rented.
Write an algebraic expression to show the total amount of money collected.
Evaluate the expression.
a. 25(5) + 10(8.5) + 35(5) + 12(8.5)
b.
So the total amount of money collected is $487.
Express each relation as a graph. Then determine the domain and range.
{(3, 8), (3, 7), (2, 9), (1, 9), ( 5, 3)}
Plot the points.
The domain is all x values of the relation, and the range is all y values of the relation. So, the domain is { 5, 1, 2, 3}
and the range is { 9, 3, 7, 8}.
{(3, 4), (4, 3), (2, 2), (5, 4), ( 4, 5)}
Plot the points.
The domain is all x values of the relation, and the range is all y values of the relation. So, the domain is { 4, 2, 3, 4,
5} and the range is { 4, 2, 3, 4, 5}.
{(0, 2), ( 5, 1), (0, 6), ( 1, 9), ( 4, 5)}
Plot the points.
