Solve the equation -2+7|4x-2|=68

1 answer:

4 0

Add 2 to each side, then divide by 7.
|4x-2|= 10. Sometimes the answer is positive, so 4x-2=10. But sometimes the answer is negative so 4x-2=-10. Add two to both equations and divide by 4 to get x= -2 and 3

If A = 8! and B = 8P8, then which one of the following is true:

meriva

Answer:

A. A = B

Step-by-step explanation:

Given

$A = 8!$

$B = ^8P_8$

Required

Which of the options is true

We start by simplifying $B = ^8P_8$

Permutation is calculated as follows

$^nP_r = \frac{n!}{(n - r)!}$

So.

$^8P_8 =\frac{8!}{(8 - 8)!}$

$^8P_8 =\frac{8!}{0!}$

0! = 1; So

$^8P_8 =\frac{8!}{1}$

$^8P_8 =8!$

Hence. B! = P!

<em>This implies that </em> $A = B = 8!$ <em />

Annalise invested $3,300 in an account paying an interest rate of 2.8% compounded monthly. Assuming

Artist 52 [7]

Answer:

$4,881.56

Step-by-step explanation:

The future value formula is ...

FV = P(1 +r/n)^(nt)

where principal P is invested at annual rate r compounded n times per year for t years.

You have P=3300, n=12, r=0.028, t=14, so the future value is ...

FV = $3300(1 +0.028/12)^(12·14) = $4881.56

There would be $4881.56 in the account after 14 years.

What is the solution to equation 8-2x+6=24

ki77a [65]

8 - 2x + 6 = 24

(8 + 6) - 2x = 24

14 - 2x = 24 <em>subtract 14 from both sides</em>

-2x = 10 <em>divide both sides by (-2)</em>
