Answer:

14 -2i

Step-by-step explanation:

9 + sqrt(-4) - ( -5 + sqrt(-16))

We know the sqrt of a negative number is i * sqrt(number)

9 + isqrt(4) - ( -5 + isqrt(16))

9 + 2i - (-5 + 4i)

Distribute the negative sign

9+2i +5 -4i

Combine like terms

14 -2i

A certain insect can beat its wings 200 times per second. Write an equation in slope-intercept form that shows the relationship
irakobra [83]

Answer:

200X = Y

Step-by-step explanation:

Since the insect in question can flap its wings 200 times per second, the equation that represents how many times it flaps its wings according to the time of flight is the following:

200X = Y

Thus, 200 is the number of times per second it flaps its wings, while X is the number of seconds in question. In turn, Y is the number of times it flaps its wings in the given time.

For example, if the insect were to fly for 5 seconds, the equation would work as follows:

200 x 5 = Y

1000 = Y
