HEElPP 25 points !! A triangle has a height of 5 feet and a base of 6 feet. What is the area of the triangle?
A=One-half(6)(5) = 8 square feet
A=One-half(6)(5) = 8.5 square feet
A=One-half(6)(5) = 15 square feet
A=One-half(6)(5) = 30.5 square feet

Solve: 3x+y=6 4x-2y=18 show all work !

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

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)
