4. The table shows the cost for a clothing store to buy - Sk jeans and khakis. The total cost for Saturday's shipment,
$1,800, is represented by the equation 15x + 20y = 1,800.
Use the x- and y-intercepts to graph the equation. Then
interpret the x- and y-intercepts. (Examples 2 and 3)

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
