A direct variation is a linear equation. It describes a simple relationship between two variables.
Example: if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Hope this helped!! :)
<u>Answer:</u>
<em>101.6 feet</em>
<u>Step-by-step explanation:</u>
<em>First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2</em>
<em>The perimeter of the four other windows: (3.6+4.8)*2=16.8</em>
<em>The total number of feet needed for the first two windows:</em>
<em>17.2*2 = 34.4 feet</em>
<em>The total number of feet needed for the four windows:</em>
<em>16.8*4 = 67.2 feet</em>
<em />
<em>The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.</em>
=gradient
Perpendicular gradient therefore is
With this info, y-y1=m(x-x1)
5(y-8)=-1(x-6)
5y-40=-x+6
5y=-x+46
Answer:
22
Step-by-step explanation:
(4 x 4) + (3 x 2) = 16 + 6 = 22
6 because 54 divided by 9 is 6
