Lin was looking at the equation 2x-32+4(3x-2462)=14x.she said”I cant tell right away there are no solutions, because on the left

Answer:
<h2>Totally disagree with Lin.</h2>When an equation don't have solution, it's because variables are cancelled or eliminated.
In this case, if we operate left side, we will have a term 14x, and the right side of the equation there's also 14x, that means that variable will be eliminated, like this:
As you can see, the equation ends in a false result, that means it doesn't have any solution, and we can tell by just seeing the first line of the equation like Lin says.
So, totally disagree with Lin, she can tell from the beginning that the equation doesn't have a solution.

Answer:
C.E.: x <em>=/=</em> -4
Step-by-step explanation:
pH = f(x) = -log₁₀x
1. Graphs
I used Excel to calculate the pH values and draw the graphs (see the Figure).
f(x) and f(x) +1 are plotted against the left-hand axis, while f(x+ 1) is plotted against the expanded right-hand axis.
The points at which pH = 0 and pH = 1 are indicated by the large red dots.
2. x = 0.5
When x = 0.5, pH ≈0.30. The point is indicated by the red diamond.
3. Transformations
(a) ƒ(x) = -log(x) + 1
This function has no y-intercept, because log(0) is undefined.
(b) ƒ(x +1) = -log(x + 1)
f(0) = -log(0 + 1) = -log(1) = 0
This function has a y-intercept at (0,0).
hope this helps please mark me brainliest!
