Answer:
x = - 5, y = 3
Step-by-step explanation:
Given the 2 equations
3x + 2y = - 9 → (1)
4x - 2y = - 26 → (2)
Adding (1) and (2) term by term eliminates the y- term, that is
7x = - 35 ( divide both sides by 7 )
x = - 5
Substitute x = - 5 into either of the 2 equations and solve for y
Substituting into (1)
3(- 5) + 2y = - 9
- 15 + 2y = - 9 ( add 15 to both sides )
2y = 6 ( divide both sides by 2 )
y = 3
Answer:
At the moment it is thrown, the height of the ball is 12 meters
Step-by-step explanation:
If the function 
models the height of the ball x seconds after it is thrown, then by this same function we can know the initial height of the ball at the initial moment.
If we represent the initial time instant as x = 0, then by doing h (0) we will get the initial height, just when the ball is thrown.
h (0) = 12 meters.
At the moment it is thrown, the height of the ball is 12 meters
