Answer:

x = 1/20 y^2

Step-by-step explanation:

This is a rightward opening (sideways ) parabola

Directrix = x = -5

Distance formula form point x,y to directrix and focus are equal:

(x - -5)^2 = (x-5)^2 + y^2

x^2 + 10x + 25 = x^2 - 10x + 25 + y^2

20x = y^2

x = 1/20 y^2

At the grocery store 1/5 of the groceries are produce. Of the produce 2/3 is vegetables. What fraction of the groceries in the g

netineya [11]

If you have 1/5 and 2/3, you need a common denominator to even do anything. So three and five both go into 15, so then you do 2 times 5, cause 3 times 5 is 15. And 1 times 3, cause 3 times 5 is 15. So you end up with 3/15 as produce, and 10/15 as vegetables. So, then you divide the fractions, 1/5 divided by 10/15, which is the same as 1/5 times 15/10. So your answer is 3/10 of the produce is vegetables.
