What is the inverse of the given relation? Y=7x^2+4

EleoNora [17]

follow these steps:

1) y-4=7x^2

2) (y-4)/7 = x^2

$x = \sqrt{ \frac{y - 4}{7} }$

so you must inverse x and y names:

${f}^{ - 1} (x) = \sqrt{ \frac{x - 4}{7} }$

A small box of cereal contains 10 cups of cereal. A medium box of the same cereal contains 30% more cereal than the small box. H

mario62 [17]

Answer:

13 cups

Step-by-step explanation:

If the small box has 10 cups, then:

(small) 10 cups = 100%

(medium) x cups = 130%

Now, cross multiply:

10 (130) = x (100)

1300 = 100x

x = 13

Another way to solve this is by turning 30% into a decimal:

30/100 = 0.3

10 (0.3) = 3

Now you have 30% of the 10 cups, but you need 30% more than the small box, so:

10 + 3 = 13 cups
