Answer:

1. It has one solution.

2. It has no solution.

Step-by-step explanation:

The given equation is

$3y+4=-2$

Subtract 4 from both the sides.

$3y=-2-4$

Divide both sides by 3.

$y=\frac{-6}{3}$

$y=-2$

Therefore this equation has only one solution.

The given equation is

$5n-4=5n-3$

Subtract both sides by (5n-3).

$5n-4-5n+3=0$

$-1\neq 0$

LHS is not equal to RHS for any value of n, therefore this equation has no solution.

Please help me with the below question.

tresset_1 [31]

We have the following three conclusions about the <em>piecewise</em> function evaluated at x = 14.75:

$\lim_{t \to 14.75^{-}} f(t) = 66$ .
$\lim_{t \to 14.75^{+}} f(t) = 10$ .
$\lim_{t \to 14.75} f(t)$ does not exist as $\lim_{t \to 14.75^{-}} f(t) \ne \lim_{t \to 14.75^{+}} f(t)$ .

<h3>How to determinate the limit in a piecewise function</h3>

In a <em>piecewise</em> function, the limit for a given value exists when the two <em>lateral</em> limits are the same and, thus, continuity is guaranteed. Otherwise, the limit does not exist.

According to the definition of <em>lateral</em> limit and by observing carefully the figure, we have the following conclusions:

$\lim_{t \to 14.75^{-}} f(t) = 66$ .
$\lim_{t \to 14.75^{+}} f(t) = 10$ .
$\lim_{t \to 14.75} f(t)$ does not exist as $\lim_{t \to 14.75^{-}} f(t) \ne \lim_{t \to 14.75^{+}} f(t)$ .
