How to solve 42 = 8m + 13m

Answers

Answer 1

Answer:

The solution to the equation 42 = 8m + 13m is m = 2.

Here, we have,

To solve the equation 42 = 8m + 13m, you can combine like terms and isolate the variable "m".

Here's how you can do it step by step:

Combine the like terms:

42 = (8 + 13)m

Simplify:

42 = 21m

Divide both sides of the equation by 21 to isolate "m":

42/21 = (21m)/21

Simplify further:

2 = m

Therefore, the solution to the equation 42 = 8m + 13m is m = 2.

Find the indicated limit, if it exists. (2 points) limit of f of x as x approaches 5 where f of x equals 5 minus x when x is less than 5, 8 when x equals 5, and x plus 3 when x is greater than 5

Answers

It looks like we have

$f(x)=\begin{cases}5-x&\text{for }x<5\n8&\text{for }x=5\nx+3&\text{for }x>5\end{cases}$

and we want to find $\lim\limits_(x\to5)f(x)$ .

Since $x$ is approaching 5, we don't care about the value of $f(x)$ when $x=5$ .

We do care about how $f(x)$ behaves to either side of $x=5$ . If $x\to5$ from below, then $f(x)=5-x$ , so that

$\displaystyle\lim_(x\to5^-)f(x)=\lim_(x\to5)(5-x)=5-5=0$

On the other hand, if $x\to5$ from above, then $f(x)=x+3$ , so that

$\displaystyle\lim_(x\to5^+)f(x)=\lim_(x\to5)(x+3)=5+3=8$

The one-sided limits do not match, since 0 ≠ 8, so the limit does not exist.
