If I'm not mistaken.. the half-life should be 40,750 years.. so

y = 40,750

I got this by multiplying 25,000 by 1.63 and then if you divide by 2.. you get

20,375.. so one of those should be correct

4^(4x-1)=32 How do I solve this problem? Do I do 4 to the fourth power first?

yKpoI14uk [10]

Answer:

$\large\boxed{x=\dfrac{7}{8}}$

Step-by-step explanation:

$4^{(4x-1)}=32\\\\(2^2)^{4x-1}=2^5\qquad\text{use}\ (a^n)^m=a^{nm}\\\\2^{2(4x-1)}=2^5\iff2(4x-1)=5\ \ \text{use the distributive property}\ a(b+c)=ab+ac\\\\(2)(4x)+(2)(-1)=5\\\\8x-2=5\qquad\text{add 2 to both sides}\\\\8x=7\qquad\text{divide both sides by 8}\\\\x=\dfrac{7}{8}$

Which of these numbers is between 1 and 3/4 ? PLEASE HELP

Elanso [62]

Since I don't see attachment, I guess the solution will be as follows:

1 & 3/4 , since 1 = 4/4, then it could be rewritten :

4/4 & 3/4, hence between these 2 fraction there is 2/4 or 1/2.

How do you convert 5y-x+4=0 into y=mx+b form?

Mashutka [201]

$5y-x+4=0$

~Add x to both sides

$5y+4=x$

~Subtract 4 from both sides

$5y=x-4$

~Divide both sides by 5

$\frac{5}{5}y= \frac{1x}{5} - \frac{4}{5}$

~Simplify

$y= \frac{1}{5} x- \frac{4}{5}$

~M= $\frac{1}{5}$

~B= $-\frac{4}{5}$
