Answer:
x = 1, y = -2
Step-by-step explanation:
2x + 5y + 11 = 0 --- Equation 1
3x - y - 8 = 0
15x - 5y - 40 = 0 --- Equation 2
Equations 1+2: 2x + 5y + 11 + 15x - 5y - 40 = 0 + 0
17x - 29 = 0
17x = 29
x = 29 ÷ 17
x = 1
Substitute x = 1 into Equation 1:
2x + 5y + 11 = 0
2(1) + 5y + 11 = 0
3 + 5y = -11
5y = -11 - 3
= -14
y = -14 ÷ 5
y = -2
Answer:
no
Step-by-step explanation:
The given lengths do not satisfy the Pythagorean theorem:
34² ≠ 33² +16²
1156 ≠ 1089 +256
The given sides do not form a right triangle.
_____
<em>Alternate solution</em>
You can also compute 34² -33² = (34+33)(34-33) = 67·1 = 67 ≠ 16².
Even simpler, a Pythagorean triple will never have zero or two even numbers. The numbers (16, 33, 34) cannot be a Pythagorean triple.
Answer:
30
Step-by-step explanation:
So to do this you would set up the equation than you would add 6 to both sides so you would get
than you would divide 3 from both sides so
and that is the final answer which is correct
