Obtuse angle because is more than 90 degrees but less than 180 degrees.
No when you subtract the 2 balances, there is a difference of 33.34. 1201.1-38.34=1162.76
Answer:
input x = - 7
Step-by-step explanation:
A is modelled as y = 5x - 4
B is modelled as y = 3x + 8
We require output of A three times the output of B , then
5x - 4 = 3(3x + 8) ← distribute
5x - 4 = 9x + 24 ( subtract 9x from both sides )
- 4x - 4 = 24 ( add 4 to both sides )
- 4x = 28 ( divide both sides by - 4 )
x = - 7 ← input
The third one is the correct choice because the solutions are 2 and -2
