The equation below describes a parabola. if a is positive, which way does the parabola open? x = ay2

For both positive and negative values of “y”, the consequent value of “x” will be positive according to given equation of parabola, i.e. x = ay^2. The coefficient “a” is a positive value.

Thus the resulting parabola will open to the right side.

An example of the proposed parabola is attached herewith.  

26?

step-by-step explanation:

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
