Answer:
8x + 2y.
Step-by-step explanation:
8 . x . 2 . y = 16xy = 16yx
Answer:
y = 9x -83
Step-by-step explanation:
Parallel lines will have the same slopes but different b values so we know that the base of this equation will be
y = 9x +b
To find b we must plus in the given coordinates and determine which value of b makes the statement true.
16 = 9(11) + b
16 = 99 + b
b = -83
Therefore the new equation will be:
y = 9x -83 or y-16 = 9(x-11)
Answer:
27mi
Step-by-step explanation:
Since the sailing course is equilateral in shape, then all their sides are equal.
Get one of the sides using Pythagoras theorem as shown;
Let one of the side be x
Two base will be x/2
According to the theorem;
x² = 9² +(x/2)²
x² = 81 + x²/4
x²-x²/4 = 81
3x²/4 = 81
3x² = 324
x² = 324/4
x² = 81
x = 9
Perimeter of the triangle = 3x
Perimeter of the triangle = 3(9)
Perimeter of the triangle = 27mi
