- Solving systems of equations by graphing
Step-by-step explanation:
Our solution set is where the 2 equations intersect. According the the graph, the systems intersect at point (-2, 1). Therefore, our answer must be A.

Step-by-step explanation:
I think it's 0.54
Area of a triangle: (1/2)bh, where b = base and h = height
(1/2) x 4 x (11/2)
= (4/2) x (11/2)
= 2 x (11/2)
= 11
Answer:
5.2 feet
Step-by-step explanation:
It helps if you can make a drawing.
You are looking for the adjacent side of the 71° angle in a right triangle and 15 is the opposite side of the angle.
Let x = the distance from the building to the base of the ladder
Tan 71 = 15/x
xtan71 = 15
x = 15/tan 71 = 5.2 feet
