Evaluate the equation -2 + 7 + (-4)

Will give brainliest immeadeately true or false: the origin woud be included in the solution set for the inequality: y< 2x-5

Right triangle xyz has a right angle at vertex y and a hypotenuse that measures 24 cm. angle zxy measures 70º. what is the length of line segment xy? round to the nearest tenth. 8.2 cm 8.7 cm 22.6 m 25.5 cm

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3
