Answer:
The answer is "
".
Step-by-step explanation:
Given:
![Line = y= -4x+3 \\ \\point= (8,1)](https://tex.z-dn.net/?f=Line%20%3D%20y%3D%20-4x%2B3%20%5C%5C%20%5C%5Cpoint%3D%20%288%2C1%29)
The formula for the standard Equation of a line:
![\to y= mx +c](https://tex.z-dn.net/?f=%5Cto%20y%3D%20mx%20%2Bc)
compare the above line value:
![m= -4\\\\c= 3](https://tex.z-dn.net/?f=m%3D%20-4%5C%5C%5C%5Cc%3D%203)
When a line is perpendicular so, the m value is: ![= \frac{1}{4}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B1%7D%7B4%7D)
Line equation when one point and m is given:
![\to (y-y_1) = m (x- x_1)\\\\\to (y-1) = \frac{1}{4}(x- 8)\\\\\to 4y-4 = x- 8\\\\\to 4y = x-8+4\\\\\to 4y = x-4\\\\\to y = \frac{1}{4}(x-4)\\](https://tex.z-dn.net/?f=%5Cto%20%28y-y_1%29%20%3D%20m%20%28x-%20x_1%29%5C%5C%5C%5C%5Cto%20%28y-1%29%20%3D%20%5Cfrac%7B1%7D%7B4%7D%28x-%208%29%5C%5C%5C%5C%5Cto%204y-4%20%3D%20x-%208%5C%5C%5C%5C%5Cto%204y%20%3D%20x-8%2B4%5C%5C%5C%5C%5Cto%204y%20%3D%20x-4%5C%5C%5C%5C%5Cto%20y%20%3D%20%5Cfrac%7B1%7D%7B4%7D%28x-4%29%5C%5C)
Answer:
7
Step-by-step explanation:
21 divided by 3 = 7
7 x 3 = 21
Answer:
23/6
Step-by-step explanation:
3 5/6 multiply 6 times 3 then add 5 which is 23 then take six and is the denominator and 23 is the numerator
C. $122.10
20 first hour
20+0.1*20 = 22 second hour
22+0.1*22 = 24.2 third hour
24.2+0.1*24.2 = 26.62 fourth hour
26.62+0.1*26.62 = 29.282 fifth hour
Total=$122.10
The answer is C. Figures K and N are parallelograms. Hope this helped !
