What is -2x-7=3(4x+7)

Mathematics
2 answers:
Ludmilka [50]3 years ago

Answer:

x= -2

Step-by-step explanation:

-2x-7=3(4x+7)

multiply numbers in parenthesis by 3

-2x-7=12x+21

move terms

-2x-12x=21+7

subtract -2x to -12x but since there negative the equation is addition. Also, add 21 to 7

-14x=28

divide both sides by -14

x= -2

What represents the inverse of the function f(x)=4x
Yuki888 [10]

Answer:

\frac{x}{4}

Step-by-step explanation:

The given function is

f(x) = 4x

As we know

f(x) = y, which implies x= f^{-1} (y)

Therefore,

y = 4x

x = \frac{y}{4}

as x= f^{-1} (y)

So,

f^{-1} (y) = \frac{y}{4}

replacing y by x in the above expression

f^{-1} (x) = \frac{x}{4}

So our inverse function is  \frac{x}{4}

A hiker discovers a skull that contains 41% of its original amount of C-14. Find the age of the skull to the nearest year
snow_tiger [21]
We need the half-life of C-14 which is 5,730 years.
Now, we will need a half-life equation:
elapsed time = half-life * log (bgng amt / ending amt) / log 2
We'll say beginning amount = 100 and ending amount = 41
elapsed time = 5,730 * log (100/41) / log 2
elapsed time = 5,730 * log ( <span> <span> <span> 2.4390243902 </span> </span> </span> ) / 0.30102999566
elapsed time = 5,730 * 0.38721614327 / 0.30102999566
elapsed time = <span> <span> </span></span><span><span><span>5,730 * 1.2863041851 </span> </span> </span>
<span>elapsed time = 7,370.523 years
