Answer:
D) Only (-1,9) is a solution.
Step-by-step explanation:
x+y =8
x^2 + y = 10
Lets check the first point (-1,9)
Put in x =-1 y =9
x+y =8
-1+9 = 8
8 =8
This works
x^2 + y = 10
(-1)^2 +9 =10
1+9 = 10
10 = 10
This works
Lets check the second point (-2,6)
Put in x =-2 y =6
x+y =8
-2+6 = 8
4=8
This does not work
We can stop now. (-2,6) cannot be a solution
Answer:
260 cm²
Step-by-step explanation:
Please see the attached picture for the full solution.
The answer is A because when you add the angles to get they equal 180. Then just solve for x.
The drawing isn't to scale
Answer:
Step-by-step explanation:
x² + 9x+8 = (x+1)(x+8)
Step-by-step explanation:
X-coordinate : (-18+0)/2 = -9.
Y-coordinate = (-2+6)/2 = 2.
Hence M(-9,2).
