Step-by-step explanation:
This equation for a parabola is given in vertex form, so it is very simple to extract the coordinates of its vertex, by using the opposite of the number that accompanies the variable "x" in the squared expression (opposite of 2) for the vertex's x-value, and the value of the constant (-6) for the vertex's y-value.
The vertex coordinates are therefore: (-2,-6)
The equation of the axis of symmetry of the parabola is a vertical line passing through the vertex. Since all vertical lines have the shape x = constant in our case, in order to pass through (-2,-6) the vertical line is defined by the equation: x = -2.
See image attached to find the vertex drawn as a red point, and the axis of symmetry as an orange vertical line passing through it.
Answer:
Mom would required 1 lbs of Sugar and 4 lbs of water.
Step-by-step explanation:
Given:
Amount of Sugar syrup Mom wants to make = 5 lbs
Percentile amount of syrup she needs to make = 20%
Solution:
Let amount of sugar to make 20% syrup be 'x'.
So by definition of proportion we get;
Now Multiplying both side by 5 we get;
So we can say that;
Amount of water =
Hence Mom would required 1 lbs of Sugar and 4 lbs of water.
