<h3>Answer:</h3>

48 1/8

<h3>Step-by-step explanation:</h3>

As written, it is evaluated as ...

... 47 + 9/8 . . . . . . . . parentheses are evaluated first

... = 47 + 1 1/8 . . . . . . then division

... = 48 1/8 . . . . . . . . then addition

_____

A decent calculator will evaluate this for you according to the order of operations. A Google or Bing search box will do that, too.

please help. will give brainliest! review the table of values for function p(x). what is lim (x -14) p(x), if it exists? (table

Lubov Fominskaja [6]

Answer:

DNE

Step-by-step explanation:

The the given table, we have;

As x approaches -14 from the left, at x = -14.001, p(x) = 1.96

$\lim \limits _{x \to -14^{-}} p(x) = 1.96$

As x approaches -14 from the right, at x = -13.999, p(x) = 1.97

$\lim \limits _{x \to -14^{+}} p(x) = 1.97$

The value of p(x) when x = -14 is $\lim \limits _{x \to -14} p(x)$ = Undefined, or is not definable, therefore, p(x) Does Not Exist (DNE) when x = -14, and we have;

$\lim \limits _{x \to -14} p(x)$ Does Not Exist, DNE.

Find the logarithmic function y = logbx that passes through the points

katovenus [111]

$b\in(0,\ 1)\ \cup\ (1,\ \infty)\\x > 0\\y\in\mathbb{R}\\--------------------------\\\\y=\log_bx\\\\For\ (1,\ 0)\to x=1,\ y=0.\ Substitute:\\\\\log_b1=0\to b^0=1\to b\in(0,\ 1)\ \cup\ (1,\ \infty)\\\\For\ (116,\ 2)\to x=116,\ y=2.\ Substitute:\\\\\log_b116=2\to b^2=116\to b=\sqrt{116}\\\to b=\sqrt{4\cdot29}\to b=\sqrt4\cdot\sqrt{29}\to b=2\sqrt{29}\\\\For\ (4,\ -1)\to x=4,\ y=-1.\ Substitute:\\\\\log_b4=-1\to b^{-1}=4\to b=\dfrac{1}{4}$

Different values of b.

<h3>Answer: There is no logarithmic function whose graph goes through given points.</h3><h3 />

Maybe the second point is $\left(\dfrac{1}{16},\ 2\right)$

Substitute:

$\log_b\dfrac{1}{16}=2\to b^2=\dfrac{1}{16}\to b=\sqrt{\dfrac{1}{16}}\to b=\dfrac{1}{4}$

<h3>Then we have the answer:</h3>

$\boxed{y=\log_{\frac{1}{4}}x}$

3.) Write an inequality for the phrase "two more than three times a number is at

stiks02 [169]

Answer:

3x + 2 ≤ 53

Step-by-step explanation:

"2 more than" means that there will be a + 2 in the equation. "3 times a number" means that 3 is multiplied by an unknown number which can be represented by a variable such as x. "At most" means less than or equal to, since the number cannot be greater than.

So generally, you might want to write the equation as 2 + 3x ≤ 53, but 2 + 3x is not in y = mx + b form. Basically, you need to write it as 3x + 2 ≤ 53 because that's how math works.
