Which equation is the inverse of y=7x^2 - 10

Mathematics
1 answer:
4vir4ik [10]3 years ago
8 0

Answer:

Depends on domain of x, could be

-√(y+10)/7; √(y+10)/7 or no solutions

Step-by-step explanation:

You need to solve it for x:

y=7x^2-10

7x^2=y+10

x^2=(y+10)/7

In order for this equation to have an inverse, you need to check the domain of x. There needs to be only one solution for x^2=(y+10)/7 - either positive or negative, depending on the domain.

I don’t really understand what to do on these questions and could you tell me the ratio to solve the rest?
SVEN [57.7K]

Step-by-step explanation:

Assuming 10 cups of lemon-lime soda and 5 cups of orange soda make 15 cups of punch, we can write proportions for each problem.

x / 130 cups punch = 10 cups lemon-lime / 15 cups punch

x = 86.67 cups lemon-lime soda

y / 130 cups punch = 5 cups orange soda / 15 cups punch

y = 43.33 cups orange soda

x / 65 cups punch = 10 cups lemon-lime / 15 cups punch

x = 43.33 cups lemon-lime soda

y / 65 cups punch = 5 cups orange soda / 15 cups punch

y = 21.67 cups orange soda

x / 195 cups punch = 10 cups lemon-lime / 15 cups punch

x = 130 cups lemon-lime soda

y / 195 cups punch = 5 cups orange soda / 15 cups punch

y = 65 cups orange soda
