I'm not 100% sure, but I am almost certain that you add your like terms on the left side. This will give you -14n+1>1. Next you want to solve like any other equation. subtract the 1 to the other side, -14n>2. Now, divide by -14. Since you are dividing, you want to flip the sign, so it says n<-1/2. That should be it. I really hope you get this right, and if you don't I'm sorry. It's been a while since I've done this kind of math.

There are six households in a rural community. Each household earns $40,000 per year. Suppose that a new resident builds a mansi

dusya [7]

Answer:

Median income has not changed

Mean income has increased

Step-by-step explanation:

Initial number of houses = 6

Earning per household = $40,000

The initial mean :

$(40,000 * 6) / 6 = $40000

Initial median :

40000, 40000, 40000, 40000, 40000, 40000

= 1/2(n+1)th term,

Median = 40000

A 7th household earns 4,000,000

Mean = ((40000*6) + 4,000,000) / 7 = $605,714

Median = 1/2(n+1)th term

40000, 40000, 40000, 40000, 40000, 40000, 4000000

Median = 4th term = 40000

Diego is solving the inequality 100 − 3x ≥ -50. He solves the equation 100 − 3x = -50 and gets x = 50. What is the solution to t

andre [41]

Answer:

x≤50

Step-by-step explanation:

100-3x≥-50

subtracting 100 at both side on inequality

-100+100-3x≥--50-100

-3x≥-150

Dividing both sides by 3

-3x/3≥-150/3

-x≥--50

Adding 50 on both sides

-x+50≥-50+50

-x+50≥0

Adding x on both sides

-x+x+50≥0+x

50≥x

so,

x≤50

I REALLY REALLY NEED HELP PLEASE <br> For the function, f (x), find f^-1 (x)<br> f (x) = e x√4−6/7

Andrews [41]

answer:

$f (x)=4x^{4} +3x^{2} +7x -15$

Explanation:

We start by integrating both sides.

$f(x)=∫16x3+6x+7dx$

$f(x)=4x4+3x2+7x+C$

Now we solve for c

$−1=4(1)4+3(1)2+7(1)+C−1=4+3+7+C−1−14=CC=−15$

Hopefully this helps!

You are downloading songs to your MP3 player. The ratio of pop songs to rock songs is 5 : 4. You download 40 pop songs. How many

katrin2010 [14]

You make fractions and do cross multiplication. so (5/4)*(40/x)= x=32. so 32 rock songs.
