You have to factor this...
So you have started with this...
x²-x-2=0
If you factor this you will get
(x+1)(x-2)=0
This gives you two solutions...
x=-1, x=2
Hope this helps! Give me a five-rate and a thanks!
150 are buying a car, right? Or solid that say cat...
-x + 2y = 10
6y = -12x + 1
6y = -12x + 1
6 6
y = -2x + ¹/₆
-x + 2y = 10
-x + 2(-2x + ¹/₆) = 10
-x + 2(-2x) + 2(¹/₆) = 10
-x - 4x + ¹/₃ = 10
-5x + ¹/₃ = 10
- ¹/₃ - ¹/₃
-5x = 9²/₃
-5 -5
x = -1¹⁴/₁₅
y = -2x + ¹/₆
y = -2(-1¹⁴/₁₅) + ¹/₆
y = 3¹³/₁₅ + ¹/₆
y = 4¹/₃₀
(x, y) = (-1¹⁴/₁₅, 4¹/₃₀)
It is intersecting, making the answer equal to C.
Answer:
mmh..
Step-by-step explanation:
sorry xould you send again the pictures? I can't see then so i cant help you...
X= 5
Set them equal to each other
2x-2=x+3
Subtract x to the other side
X-2=3
Add two to the other side
X=5
Hope it helps
