Answer:
The equation of the line is y = 2x + 6
For all of them just use the Pythagorean theorem which is a squared plus b squared equals c squared where c is the hypotenuse (length of the side opposite the right angle) and a and b are legs. Just plug it in and solve for the missing length. For example, 1 would be (12) squared plus (5) squared equals c squared
Simplify to get 144 plus 25=c squared
169 equals c squared
Find the square root of both sides
c=13

As far as I can tell you got them all correct, well done :D
The number of weeks required to have enough money in account to buy computer is 12
<em><u>Solution:</u></em>
Given that Maya has $210 in a savings account for a new computer the computer cost $537.15 including sales tax
At the end of each week she deposits $27 into the account
<em><u>To find: number of weeks required to have enough money in the account for the computer</u></em>
Total cost of computer = $ 537.15
Amount in savings account = $ 210
Let "a" be the number of weeks required to have enough money in account to buy computer
Each week she deposits $27 into the account
<em><u>So we can we frame a equation as:</u></em>
total cost of computer = Amount in savings account + (number of weeks x 27)
![537.15 = 210 + a \times 27\\\\537.15-210 = 27a\\\\27a = 327.15\\\\a = 12.11](https://tex.z-dn.net/?f=537.15%20%3D%20210%20%2B%20a%20%5Ctimes%2027%5C%5C%5C%5C537.15-210%20%3D%2027a%5C%5C%5C%5C27a%20%3D%20327.15%5C%5C%5C%5Ca%20%3D%2012.11)
![a \approx 12](https://tex.z-dn.net/?f=a%20%5Capprox%2012)
Thus number of weeks required is 12 approximately
