In f(x) = 3x + 2, the x is being represented in the function. So, if we replace the x with the g(x) functions, we get:
f(g(x)) = 3(2x - 4) + 2
f(g(x)) = 6x - 12 + 2
f(g(x)) = 6x - 10
The dependent value is determine by the value of the independent value. in other words, the dependent value is what you get when you take the independent value and substitute it in the original equation or situation. The relationship is multiplicative because you must first multiply the independent value in the equation where the x is before you can add or subtract to get your answer.<span />
The area of the square is 81 sq in, and the area of the circule is (3.14)(3 in)^2, or approx 3.14(9) sq in, or approx 28.27 sq in.
Subtract: 81 sq in - 28.27 sq in = approx. 52.73 sq in.
The difference is 52.73 sq in; the square is larger, the circle smaller.
Well you will just subtract 91 - 7 which equals 84.
So 7 + 84 = 91
The answer is 90, there is 10 millimeters in 1 centimeter! So, if there is 9 centimeters, there will then be 90 millimeters!
Ps: I had my question up but someone reported it since I added a picture that would help you! :(
Hope this does help though! You can always do the jumping trick with meters! That's how I learned :)
