Which statement describes the mapping?
icang [17]

Answer:

Third one

Step-by-step explanation:

To be a function x must only have 1 y value or you're really describing a limit which isn't part of the outputs

However, In your case two x values equaling the same y value is fine because the x values do not have two y values

This is a function, as each x value corresponds to one y value

My apologies I was confused with my first answer.

An isosceles right-angled triangle is shown.
Bad White [126]

Answer:

\boxed{x=4}

Step-by-step explanation:

Area of triangle = 0.5 × Base × Height

200 = 0.5 × 5x × 5x

→ Simplify

200 = 12.5x²

→ Divide both sides by 12.5

16 = x²

→ Square root both sides

4 = x ∴ x = 4
