Is 7- y=5x+11 a standard form

Austin was practicing combining integers and wrote different integers on some paper. He randomly selected four pieces of paper.

OlgaM077 [116]

Answer:

Final solution = -10

(-9)+4+6+(-11)

-9 + 4 +6 (+-11) you need to show

-9 +4 +6 + (-11) calculator shows

= -5 + 6-11 is both results.

= 1-11

= -10

Evaluate log(-13) Correct answer will get brainliest

Sedaia [141]

if given log(a)=b, where no base is stated, we assume base 10, or $log(a)=log_{10}(a)$

also, $log_a(b)=c$ translates to/can be written equivilently as $a^c=b$

therefore, given

$log(-13)=?$ where we want to find ?

assume base 10 and translate

$10^?=-13$

since we cannot raise a positive number to any real power and give a negative number, ? is not a real number and therefore, there are no real solutions

if we do want to find a solution, we can use Euler's idendity

$e^{\pi i}=-1$ where i is the complex number i=√-1 and e is euler's number

we can try to change bases to find the value of ?

$e^{\pi i}=-1$

$13e^{\pi i}=-13$

so

$13e^{\pi i}=10^?$

taking ln of both sides

$ln(13e^{\pi i})=ln(10^?)$

using log rules

$ln(13)+(\pi i)ln(e)=(?)ln(10)$

$ln(13)+\pi i=?ln(10)$

divie both side by ln(10)

$\frac{ln(13)+\pi i}{ln(10)}=?$

in a+bi form

$?=\frac{ln(13)}{ln(10)}+\frac{\pi}{ln(10)}i$

there are no real numbers that it evaluates to

however, it does evaluate to a complex number which is $\frac{ln(13)}{ln(10)}+\frac{\pi}{ln(10)}i$ or aproximately 1.11394+1.36438i

Emily researched the average prices of desktop PCs worldwide since 2000. She could only find data from 2005 to 2010. She created

gregori [183]

Answer: There is a linear relationship between the average price of PCs and the number of years that have passed since 2000.

Step-by-step explanation:

From the given graph, we can see there is a straight line , which shows that there is a linear relationship between both quantities.

As the number years increases the average price of PCs decreases.

The given equation of the line is $y=-39x+998$ , which shows that the slope of the line is -39, i.e the rate of decrease in the average price of PCs with respect to the the number of years that have passed since 2000.

The question is asking me choose all of the numbers that are unit fractions, and here are my options, 14 <16 14 <16 510&lt

____ [38]

Answer:

$(d)$ $\frac{4}{8}>\frac{2}{6}$

Step-by-step explanation:

Given

$\frac{1}{4}$

$\frac{5}{10}$

$\frac{1}{2}>\frac{1}{3}$

$\frac{4}{8}>\frac{2}{6}$

$\frac{3}{5}>\frac{4}{5}$

Required

Select the unit fractions

If we are to go by what a unit fraction means: it means that the numerator of the fraction must be 1 and must be written as a single fraction i.e. $\frac{1}{2}$  and not as an inequality i.e.  $\frac{3}{5}>\frac{4}{5}$
