It will take Jon 240 minutes or 4 hours.
5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4

Answer:
Correct!
Step-by-step explanation:
That’s right
Equation :
This parabola is facing downwards and highest point of the parabola is it's vertex.
Highest point is (-2,2)
so the vertex is (-2,2)
The graph is passing through (-1,0)
Equation in vertex form is


Substitute back in Equation

the graph has two x intercepts -1 and -3
that means (x+1) and (x+3) are the factors
multiply factors to get the equation in standard form

-2x^2-8x-6=0
