Answer:

x=0 for f(x)=\frac{P(x)}{Q(x)}, with Q(x) \neq 0.

Step-by-step explanation:

To obtain x-intercepts, we need to give certain value, specifically x=0.

However, in case of a rational function, we must make sure that x=0 doesn't makes the denominator null, beacuse in that case the function is undefined.

Therefore, for x-intercepts we must say

x=0 for f(x)=\frac{P(x)}{Q(x)}, with Q(x) \neq 0.

7x + 3y = m
attashe74 [19]

7x + 3y = m

3y = m - 7x

y = (m - 7x) / 3


4( r + 3 ) = t

r + 3 = t / 4

r = ( t - 3 )/ 4


2x + b = w

2x = w- b

x = ( w - b ) / 2


x (1 + y) = 2

x = 2 / 1 +y
