10^1 = .2
10^2 = 2.0
10^3 = 20.0
So, the answer is 3.
Answer:
f(x) + 2.
Step-by-step explanation:
Example:
If we have say f(x) = x + 1 then 2 units will be added to f(x) when it is moved up 2 units.
So the equation of this line will be f(x) + 2 which in this example is
x + 1+ 2.
The new function is x + 3.
<span>let x be number of bicycles
and y the number of</span> tricycles<span>
So
x + y = 25 equation 1
The number of wheels is
2x + 3y = 63 equation 2
</span>We can multiply the equation 1 by two and subtract from the second one...
2x + 3y = 63
-(2x + 2y = 50)
then
y = 13 trikes and
x = 12 bikes
