To start take the equation and then plug in 9 for x
3x+4y=43
3(9)+4y=43
27+4y=43
Subtract 27 from each side to get all of the y's by themselves
27+4y-27=43-27
4y=16
Divide by four to get the value of one y
4y/4=16/4
y=4
Answer:
<u>0</u><u>.</u><u>4</u><u>2</u>
Process:
1 - 0.58
<u>0</u><u>.</u><u>4</u><u>2</u>
Y1 = 0.55
y2= 0.1
-81.81818181% using this formula <span>((y2 - y1) / y1)*100 = your percentage change.
Thus ((0.55 - 0.1) / .55)*100 = -</span>81.81818181818181818181818181....
Y = f(x)
The initial value will be the first point. (0,3)
3 = initial value of function, f(0)
