Afunction is defined as follows: for which x-values is y = -9? select all that apply.-4.5-339

3

Step-by-step explanation:

y = -9 when x = 3

When x = -4.5, the first definition of the function will be used since -4.5 is less than -3. In this region, y = -x implying that when x = -4.5,  y= 4.5.

When x = 3, the last definition of the function will be used since 3 is greater than -2. In this region, y = -x^2 implying that when x = 3,  y= -9.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
