Answer:
My example:
1. Get the equation in the form y = ax4 + bx + c
2. Calculate -b / 4a. This is the x coordinate of the vertex
3. To find the y coordinate of the vertex, simply plug the value -b / 4a into the equation for x and solve for y.
Step-by-step explanation:
y=2x^2 -16x +30
vertex: ( 4, -2)
Focus: (4, -15/8)
Axis of symmetry: x = 4
Directrix: y = -17/8
The height of glass 1 which in cylindrical in shape is 7.6 centimeters. Since the total volume of water added by Celia is 100 cubic centimeter, and the volume of glass 2 is 26.4 cubic centimeter which is a conical in shape. Subtracting the volume of glass 2 from the total volume glass 1 can be calculated and its height.
Answer:
7:10
Step-by-step explanation:
14/20= 7/10
Answer:
x =127
Step-by-step explanation:
Since this is a 6 sided figure, the sum of the interior angles is 720
128+133+112+x+120+100 = 720
Combine like terms
x+593=720
Subtract 593 from each side
x+593-593 = 720-593
x =127
We can start from 
and multiply/divide both sides to generate an equation that has -5 as a solution. For example, if we multiply both sides by 3, we have
And this equation must be solved by dividing both sides by 3.
Vice versa, if we divide both sides by 2, we have
And this equation must be solved by multiplying both sides by 2.
