What are the real zeros of x^3+4x^2-9x-39

3.07

Step-by-step explanation:

The zeros of the function also called the roots are the x-intercepts where the function crosses the x-axis. The zeros are the x-values at these points. To find them, graph the function and look closely around the x-axis for intercepts.

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
