Answer:
One Solution

Step-by-step explanation:
Given

Required
Determine the number of solution and the value of x
The equation is a linear equation and they have just one solution
Solving further [Divide both sides by -10]



Hence;
<em>x has only one value</em>
Os números que não são racionais são os da opção C)
Multiple each of those by 5000, getting 35000, 14000, and 10000
F(x)=3x+1 (preimage)
g(x)=x+1 (image)
it is undergoing a reduction/compression with translation.
In general, a linear transformation is
g(x) = a*f(bx-h)+k
h=horizontal translation (right if h>0, left if h<0, note formula has minus sign)
k=vertical translation (up if k>0, down if k<0)
a=vertical stretching, (stretching if |a|>1, compression if |a|<1, also, if a<0, a reflection across the x-axis is performed)
b=horizontal stretching (|b|>0 compression, |b|<0 stretching, also, if b<0, a reflection across the y-axis is performed)
In this case,
g(x)=f(x/3), so it is a horizontal stretching.
Note that the y-intercept remains unchanged.
The answer is 3 :) hope this is right
