Slope is rise/run or y2-y1/x2-x1. So to find the slope, find two points where the point is exact, then do the equation. That's the best I can explain, sorry if this doesn't help at all.
Answer:
the first one
Step-by-step explanation:
y = 3x/3
y = x
We set up a proportion to do this. There are 100 cm in 1 meter to we use this:
700 cm ( 1 m / 100 cm )
The cm's will cancel each other out since there is one in both the numerator and the denominator.
This leaves you with:
700 / 100 = 7.
The only units left when the centimeters cancel out is meters.
So there are 7 meters in 700 centimeters.
Answer:
f(x) = 2·3^x
Step-by-step explanation:
We have the general equation of exponential functions as
y= a*b^x
We are given that the point (0,2) is on the graph so
when x= 0, y= 2
If we substitute in the general equation we see that
2 = a*b^0, any number to the power 0 is 1
2 = a
We were also given that point (1, 6 ) is on the graph;
If we substitute in our new found equation we see that
y=2·b^x
6 = 2·b^1 , any number to the power 1 is itself and
divide both sides by 2
3 = b
f(x) = 2·3^x
Should be around 1122.37. Hope this helps.
