well, you already know an absolute value expression has a ± siblings, so let's proceed without much fuss.


\bf |2x-5|=4\implies  \begin{cases} +(2x-5)=4\implies 2x=9\implies x=\cfrac{9}{2}\\[-0.5em] \hrulefill\\ -(2x-5)=4\implies 2x-5=-4\\[1em] 2x=1\implies x=\cfrac{1}{2} \end{cases}

How do I get the ans??
ioda

Answer:

11 sets of forks

Step-by-step explanation:

First subtract 406-278 to find total amount of forks needed which is 128 forks.

Then divide 128 by 12 to see how many sets of forks you need.

You get 10.67 but because you can't buy two thirds of a set, you have to round up to 11 sets of forks.

Hope this helps :)

Apply root test to the series.
Angelina_Jolie [31]
\displaystyle\lim_{n\to\infty}\sqrt[n]{\left|\left(\frac{5n+15}{2n-1}\right)^n\right|}=\lim_{n\to\infty}\frac{5n+15}{2n-1}=\dfrac52

Since this limit exceeds 1, the series diverges.

If a towns population currently at 50,000 experiences 5% growth every 10 years, what will its population be in 25 years
disa [49]

Answer:

56503

Step-by-step explanation:

this grows exponentialy so at the start it would be 50,000 growing by 5% every ten years. but since there is only 2 ten years in 25 years we must cut the percent in half making 2.5%

Step 1

(50,000×5%)+50,000= 52500

Step 2

(52500×5%)+52500= 55125

step 3

(55125×2.5%) +55125= 56503
