Step-by-step explanation:
√a is defined only when a >= 0.
Therefore for √4x * √(x + 2) to be defined, both 4x and x + 2 must be non-negative.
When 4x >= 0, x >= 0.
When x + 2 >= 0, x >= -2.
x >= 0 and x >= -2, therefore we have x >= 0. (D)
Answer:
20
Step-by-step explanation:
The input (X) is 10. The output (Y) is 2X Which means 2 times X. So your answer is 2 × 10 which is 20.
Answer:
I did Mental Math and Got 6!
5 times -5 +1 is -9 , -9/2 needs a 4 for the denominator to divide I think and so that would make it -18/4, and -18/4 divided by -3/4 is 6/1 which equals 6.
The answer is D- negative correlation
Answer:
The Answer is: y = -3x + 6
Step-by-step explanation:
Given point (0, 6) and slope -3, begin with the point slope form of the equation:
y - y1 = m(x - x1)
y - 6 = -3(x - 0)
y - 6 = -3x
y = -3x + 6
Hope this helps! Have an awesome day!! :-)
