2(2x - 8) = x - 46 ?

Mathematics
2 answers:
True [87]2 years ago

Answer:

x = -10

Steps:

2(2x - 8) = x - 46  Multiply 2 and 2x, and multiply 2 and -8

4x - 16 = x - 46  You then have this equation

-x           -x  Subtract x from both sides

<em>Now let me stop here.  Why are we subtracting?  Because we have variables on both sides, we subtract the least number with the variable. We have 4x and we have </em>x<em>.  Now, x means 1x, and 1x is less than 4x. Therefore, we subtract 1x from both sides : 4x - 1x = 3x.</em>

3x -16 = -46  Then you get this

    +16   +16  Add 16 to both sides (if it said 3x +16 = -46, then you'd subtract)

<u>3x</u> = -<u>30</u>  You now have this

3       3  You only want x, so divide 3 from both sides

x = -10  Hope this helps!

Answer: X = -10

Step-by-step explanation:

Times two to the parentheses

Minus X from both sides, left with 3X-16=-46

Add 16 to both sides 3X=-30

Divide both sides by 3

Answer X=-10

Questions 2-7 will all be in regards to this data set:Observation X Y1 20 302 23 353 28 404 26 385 24 376 32 457 35 508 24 349 3
Tomtit [17]

Answer:

r =0.4437

Step-by-step explanation:

We have the follwoing dataset:

X: 20,23,53,4,24,32,35,24,31,23

Y: 30,35,40,38,37,45,50,34,42,32

n=10

The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.

And in order to calculate the correlation coefficient we can use this formula:

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n\sum x^2 -(\sum x)^2][n\sum y^2 -(\sum y)^2]}}  

For our case we have this:

n=10 \sum x = 269, \sum y = 383, \sum xy = 10609, \sum x^2 =8645, \sum y^2 =15007  

Th excel figure attached shows the calculations for each sum.

r=\frac{10(10609)-(269)(383)}{\sqrt{[10(8645) -(269)^2][10(15007) -(383)^2]}}=0.4437  

So then the correlation coefficient would be r =0.4437

Factor p^2−6−q·(p^2−6)^2
Olenka [21]

Answer:

(p^2−6) (1-q(p^2-6))

Step-by-step explanation:

p^2−6−q·(p^2−6)^2

Put parentheses around the P^2-6 at the beginning of the expression

(p^2-6) -q (p^2−6)^2

Factor out (p^2−6)

(p^2−6) (1-q(p^2-6))
