7 = -16t2 + 16t + 3
7 = t2 + 3
7 -3 = t2 + 3 - 3
4 = t2
square root of 4 = square root of t2
2 = t

Answer:
-3
Step-by-step explanation:
the answer would be -3 because it just makes sense I guess
Option b is right answer because v.w means 4 x -5,6 x -6 and -5 x -3.
Note-x means multiply.
I think the answer should be C, that is the closest answer
Solve for x
6x+5y=-15
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3
