The graph h = −16t^2 + 25t + 15 models the height and time of a ball that was thrown off of a building where h is the height in
Olenka [21]

Answer:

A

Step-by-step explanation:

If you graph the equation f(x) = -16x^2+25x+15. You would need to pay attention to the x value which is somewhere in between 0.75-0.9.

Another way is to convert the equation into vertex form.

Solve 16x+9=9y−2x16x+9=9y−2x for y
denis23 [38]
16x + 9 = 9y-2x   Add 2x to both sides
18x + 9 = 9y        Divide both sides by 9
  2x + 1 = y           Switch the sides to make it easier to read
         y = 2x + 1

I need help with my math work.
Lesechka [4]

There's not much math work here, they just want you to eyeball the graph and give the closest grid point to where the two lines meet.

Let's translate the question.

Solution to the system

That's the x and y values where the two lines cross.  That's because the meeting point is the value of x and y that satisfies both equations.

Approximation ... to the nearest integer values

Where two integer grid lines cross is called a lattice point.  It's a point with integer coordinates.  Our solution, the meet of these two lines, doesn't fall exactly on a lattice point.  The nearest integer values means the closest lattice point to our intersection of lines.

Eyeballing the graph, I'd say (x,y)=(2,3) is the closest point.

Answer: (2,3)   second choice
