Answer:
A is the correct answer
Step-by-step explanation:
To get the fastest answer for these kind of questions, you just have to apply (0, -2) into either one of the 2 equations:
2 * 0 - 6 * (-2) = 12
0 - (-12) =12
0 + 12 = 12 (TRUE)
So the solution will be (0, -2)

Answer:
I beleive it would be y = x + 7
Step-by-step explanation:
Im sorry if im wrong, its just you didnt supply the other coordinates
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0.
Now solve the equation: 12t=-20t+72,
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours.
Now the equation of the <span>pigeon is like this: x = 48t.
</span>Then for t = 2.25, we get

The Hyde has flown 108 km when the trains meet.</span>
Answer:
(2, 7 )
Step-by-step explanation:
Given the 2 equations
y = 2x + 3 → (1)
y = 3x + 1 → (2)
Substitute y = 3x + 1 into (1)
3x + 1 = 2x + 3 ( subtract 2x from both sides )
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into either of the 2 equations for corresponding value of y
Substituting x = 2 into (1)
y = 2(2) + 3 = 4 + 3 = 7
Solution is (2, 7 )
