Answer:
Step-by-step explanation:
Given points are :
x = -2 0 4
y=f(x) = 0 -6 78
We have to model the parabola with the help of these points
Solution:
We consider a standard equation of parabola 
now, we put the points in the equation we get,
at (-2,0) is 4a-2b+c=0
at (0,-6) is c=-6
at (4,78) is 78= 16a+4b+c
now, solving these equation we get, a= 4 , b= 5 , c= -6
so the equation formed with these points is
we can see this in the graph attached.
Answer:
3x + 6 = 24.1
Step-by-step explanation:
The product of 3 and a number (x) increased (adding) by 6 is 24.1 (the result).
Answer:
Let the x = # of pies Larry ate
Jesse ate 2x-5 pies
Total = 16
Your equation is:
x + (2x-5)=16
3x-5=16
3x=21
x = 7
Larry ate 7 pies.
Step-by-step explanation:
X is greater than or equal to 8
x is greater than or equal to 2
Step-by-step explanation:
the question is asking for the volume of water in m^3 that will be in the pool when it is completely full.
we find this by multiplying the length times the width times the depth.
this gives us 50m×25m×2.5m= 3125m^3
