The endpoints of GE are located at G(–6, –4) and E(4, 8). Using slope-intercept form, write the equation of GE.

iogann1982 [59]

( y1 - y2 ) / ( x1 - x2 )
In this case, I calculated it to be 12/10, or 6/5
Next, we choose a point to use in our formula. I'll use point E since it does not have any negative signs.
The final slope-intercept equation is then:
y - 8 = 6/5 * ( x - 4 )

HELPPPPPPPPPP!!!!!!! Calculate the correlation coefficient for the following data, showing all work. What does it tell you about

stiks02 [169]

Answer:

I will show the way.

Step-by-step explanation:

r is the correlation coefficient

$r=\frac{SSxy}{\sqrt{(SSxx)(SSyy)}}$

To find SSxy

SSxy= ∑ $xy$ - ∑ $\frac{(x)(y)}{n}$

To find SSxx

SSxy= ∑ $x^{2}$ - $($ ∑x $)^{2}$ /n

To find SSyy

SSxy= ∑ $y^{2}$ - $($ ∑y $)^{2}$ /n

if your r is near +1, it shows strong positive correlation. Y is proportional to X.

And if it nears -1, it would show strong negative correlation. Y is inversely proportional to X.

I need help with this V-4=v+2+7v-42 ??

zubka84 [21]

Answer:

$\boxed{\bold{v \ = \ \frac{36}{7}}}$

Step-by-step explanation:

Subtract v from both sides

$\bold{v-4-v=v+2+7v-42-v}$

Simplify

$\bold{-4=2+7v-42}$

Switch sides

$\bold{2+7v-42=-4}$

Group like terms

$\bold{7v+2-42=-4}$

Subtract the numbers: 2 - 42 = -40

$\bold{7v-40=-4}$

Add 40 to both sides

$\bold{7v-40+40=-4+40}$

Simplify

$\bold{7v=36}$

Divide both sides by 7

$\bold{\frac{7v}{7}=\frac{36}{7}}$

Simplify

➤ $\bold{v=\frac{36}{7}}$

You deposit $2200 into three separate bank accounts that each pay 3% annual interest. How much interest does each account earn a

Keith_Richards [23]

This can be solve using the formula:
F = P ( 1 + i)^n
where F is the money after n years
P is the initial amount of money
i is the annual interest rate
n is the time in years
since you deposit in 3 accounts P = 2200/3
F = ( 2200 / 3) ( 1 + 0.03)^6
F = $ 875.64 is the money each account earned after 6 years
