Answer:
D, -5x +12
Step-by-step explanation:
y = -5x + b
2 = -5(2) + b
2 = -10 + b
b =12
y= -5x +12
Answer:
$7.40
Step-by-step explanation:
The area of a shape is the amount of space covered by the shape.
<em>The area to be tiled is 8.40 square meters</em>
The length of the side walls are given as:
![L1= 1.7m](https://tex.z-dn.net/?f=L1%3D%201.7m)
The length of the back wall is given as:
![L_2 = 5m](https://tex.z-dn.net/?f=L_2%20%3D%205m)
The height to be tiled is:
![Height =1m](https://tex.z-dn.net/?f=Height%20%3D1m)
<u>The area of the 2 side walls is:</u>
![A_1 = L_1 \times Height \times 2](https://tex.z-dn.net/?f=A_1%20%3D%20L_1%20%5Ctimes%20Height%20%5Ctimes%202)
![A_1 = 1.7m \times 1m \times 2](https://tex.z-dn.net/?f=A_1%20%3D%201.7m%20%5Ctimes%201m%20%5Ctimes%202)
![A_1 = 3.4m^2](https://tex.z-dn.net/?f=A_1%20%3D%203.4m%5E2)
<u>The area of the back wall is:</u>
![A_2 = L_2 \times Height](https://tex.z-dn.net/?f=A_2%20%3D%20L_2%20%5Ctimes%20Height)
![A_2 = 5m \times 1m](https://tex.z-dn.net/?f=A_2%20%3D%205m%20%5Ctimes%201m)
![A_2 = 5m^2](https://tex.z-dn.net/?f=A_2%20%3D%205m%5E2)
<u>The tile area is:</u>
![Area = A_1 + A_2](https://tex.z-dn.net/?f=Area%20%3D%20A_1%20%2B%20A_2)
![Area = 3.4m^2 + 5m^2](https://tex.z-dn.net/?f=Area%20%3D%203.4m%5E2%20%2B%205m%5E2)
![Area = 8.40m^2](https://tex.z-dn.net/?f=Area%20%3D%208.40m%5E2)
<em>Hence, the area to be tiled is 8.40 square meters</em>

Answer:
The general equation of a circle is x2 + y2 - 6x - 16y + 48 = 0
Step-by-step explanation:
Answer:
The answer in decimal is 0.56 and in fraction is ![\frac{14}{25}](https://tex.z-dn.net/?f=%5Cfrac%7B14%7D%7B25%7D)
Step-by-step explanation:
![\frac{140}{250} =\frac{14\times 10}{25\times 10}\\ \textrm{the number 10 will be cancelled from numerator and denominator we get}\\= \frac{14}{25}\\\textrm{now multiply by 4 in numerator and denominator such that denominator becomes hundred}\\= \frac{14\times 4}{25\times 4}\\= \frac{56}{100}\\= 0.56](https://tex.z-dn.net/?f=%5Cfrac%7B140%7D%7B250%7D%20%3D%5Cfrac%7B14%5Ctimes%2010%7D%7B25%5Ctimes%2010%7D%5C%5C%20%5Ctextrm%7Bthe%20number%2010%20will%20be%20cancelled%20from%20numerator%20and%20denominator%20we%20get%7D%5C%5C%3D%20%5Cfrac%7B14%7D%7B25%7D%5C%5C%5Ctextrm%7Bnow%20multiply%20by%204%20in%20numerator%20and%20denominator%20such%20that%20denominator%20becomes%20hundred%7D%5C%5C%3D%20%5Cfrac%7B14%5Ctimes%204%7D%7B25%5Ctimes%204%7D%5C%5C%3D%20%5Cfrac%7B56%7D%7B100%7D%5C%5C%3D%200.56)
