The graph of f(x) = sqrt( 4x) looks like this. So choose the one that looks like the image attached.
The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.
In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.
I am not completely sure but Khan Academy might show how to do that. Or it might at least give an example.
Answer:
£1 = 25 hits
Step-by-step explanation:
Will get the equation is
so, X=25
x = What we want to find
Answer: -44
Step-by-step explanation: PEMDAS(Parenthesis; Exponent; Multiply; Divide; Add; Subtract)
First you multiply the seven with the other seven to get 49. The problem will look like this: (-3) + 8 - 49. Now just add the -3 and 8. You'd get 5.
Now the problem looks like this: 5 - 49. And you then get -44.
