Angelo bought apples and bananas at the fruit salad. he bought 20 pieces of fruit and spent $11.50. apples cost $0.50 and bananas cost $0.75 each. write a system of equations to model the problem. (hint: one equation will represent the number of pieces of fruit. a second equation will represent the money spent on the fruit.)

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0

In the diagram of circle o, what is the measure of zabc?
