Answer:
<u>(1, 18)</u>
Step-by-step explanation:
Rewrite the equation in vertex form by completing the square for -3x^2 + 6x + 15. This = -3(x - 1)^2 + 18.
Set y equal to the new right side.
y = -3(x - 1)
Use the vertex form, y = a(x - h)^2 + k, to determine the values of a, h, and k.
a = -3
h = 1
k = 18
Vertex = (h, k) / (1, 18)

Answer:
8x + 11= 315
Step-by-step explanation:
Let x = the number of students in a bus
There are 8 buses
8x is the number of students in buses
There are 11 students in cars
Add this together to get all the students, which is 315
8x + 11= 315
