Yes because the hypotenuse would be the longest side (13) and when squared equals 169. now when you square 5 and 12 (25 and 144) and add them, you get the 169, which is 13. so yes it’s a right triangle.
Answer: 3/8 + 4/5 = <u>1 7/40</u>
4/5 = 32/40
3/8 = 15/40
32/40 + 15/40 = 47/40
47/40 = 
Hope this helped! Have a great day! :D
Answer:
The slope has to be the same so adjust the y-intercept.
Step-by-step explanation:
y=1/2x-10.5
The solution of system of equations is: x = 1.6 and y = 1.2
Step-by-step explanation:
Given equations are:

Putting
in equation 2

Putting x = 1.6 in equation 2

Dividing both sides by -3

Hence,
The solution of system of equations is: x = 1.6 and y = 1.2
