Answer:
18
Step-by-step explanation:
It does represent a direct variation.
Direct variation: y = kx
y varies directly with x
Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2 + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2

Answer:
Height of the sail is 15 inches.
Step-by-step explanation:
Given:
Area of the fabric =
Base of the sail = 8 in.
We need to find the height of the sail.
Solution:
Let the height of the sail be 'h'.
Now we know that;
Area of Triangle is given by half time base multiplied by the height.
framing in equation form we get;
Dividing both side by 4 we get;
Hence height of the sail is 15 inches.
-3x = -3 because you would multiply one of the equations by -1 to eliminate y.
