This system has one solution what is the y-coordinate of the solution y=5x-20 y=x^2-9x+29

y = 15

Step-by-step explanation:

Even tho' we're supposed to find y here, it's easier to eliminate y first, find x and then go back and calculate y.

Both given formulas have already been solved for y:

y=5x-20  and  y=x^2-9x+29

We can equate them:   5x-20 = x^2-9x+29.  

Next, move the terms 5x - 20 to the right side:

                                                0  = x^2-9x+29 - 5x + 20, or

                                                 0 = x^2 - 14x + 49

This last result is the square of a binomial:  the square of x - 7.

Thus, there are two identical, real solutions:  {7, 7}.

Now go back to  y = 5x - 20, substitute 7 for x and calculate the y-coordinate:

y = 5(7) - 20 = 15

The y coordinate of the solution is 15.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
