The vertex is the point at which the parabola or quadratic equation opens up or down. To calculate the parabola, we must use the formula: -b/2a = x; x = -16/2(4) x = -2
Substitute -2 in where you see x appear and do the arithmetic to find that y = -15. Therefore, the vertex coordinates are (-2,-15).
Answer:
180 miles
Step-by-step explanation:
The are moving towards each other at 50 mph and 40 mph which is the same as 90 mph. They are moving 90 mph closer to each other every hour so in 2 hours it would be 180 miles.
Answer:x=12
Step-by-step explanation:
5x+9-3x=18+15
First of all, in the case of a equation that has one vatiable having one power ,you need to bring all the variable together in one side.
5x-3x=18+15-9
0r,2x=18+6
Or,2x=24
Or,x=24/2
Or,x=12
So it's the solution..
