Notice the picture
the rhombus, or kite, is really just 4 triangles
all sides are the same lenght in a rhombus,
thus, find the area of all of the triangles,
and you already have two sides given,
and then, add them up
or just find the length of one, and multiply times 4 :)
recall, area of a triangle = 1/2 bh
(y-y1) = m(x-x1)
y-2 = 5(x-6)
Therefore, point (x1,y1) lies on the line of equation
Therefore, point (6,2) lies on the line with the point slope equation y-2=5(x-6)
Answer:
1) 15 feet per second
2) distance after 3 seconds 45 feet
3) slower
Step-by-step explanation:
1) 30/2 = 15
2) 15 x 3
3) 55/4 = 13.75 < 15
Answer:
A. y=2x-9
B. 
Step-by-step explanation:
A. Parallel lines have the same slope. That means the line y=2x+3 has the same slope as any line parallel to it. So the slope is 2.
Using m=2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

B. Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=2x+3 is 2. The slope perpendicular to it is -1/2.
Using m=-1/2, substitute it and (4,-1) into the point slope form and simplify to find the y-intercept.

Answer:
x = 2
Step-by-step explanation:
if the line passes through the x axis it means we should use the of x
if it passes through y we should use value of y
in this question perpendicular means at a 90 degree angle
the coordinates is 2,6
so x must be 2
