6. Find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel
prisoha [69]
<h3><u>The equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8 is:</u></h3>

y = \frac{5}{4}x + 13

<em><u>Solution:</u></em>

Given that,

We have to find the equation in slope-intercept form for the line that passes through the point (-8, 3) and is parallel  to the line -5x + 4y = 8

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c

Where "m" is the slope of line

From given,

-5x + 4y = 8

Rearrange to slope intercept form

4y = 5x + 8

y = \frac{5x}{4} + \frac{8}{4}\\\\y = \frac{5x}{4} + 2

On comparing the above equation with slope intercept form,

m = \frac{5}{4}

We know that, slopes of parallel lines are equal

Therefore, slope of line parallel  to the line -5x + 4y = 8 is:

m = \frac{5}{4}

\text{Substitute } m = \frac{5}{4}\ and\ (x, y) = (-8, 3) \text{ in eqn 1}

3 = \frac{5}{4} \times -8 + c\\\\3 = -10 + c\\\\c = 13

Substitute c = 13 and m = 5/4 in eqn 1

y = \frac{5}{4}x + 13

Thus the equation of line in slope intercept form is found

If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>

The standard deviation of the distribution of sample means is​ _______.
luda_lava [24]

Answer:

Standard error

Step-by-step explanation:

The standard deviation of the distribution of sample means is called the standard error of the means.

It is denoted by: \sigma_{\bar X}

The standard error is calculated using the formula: \sigma_{\bar X}=\frac{\sigma}{\sqrt{n} }

where n is the sample size and \sigma is the population standard deviation.

PLEASE ANSWER ASAP!!!
yaroslaw [1]

Answer:

-6 is the x-coordinate value

Step-by-step explanation:

Mathematically, slope can be calculated as;

m = (y2-y1)/(x2-x1)

For the value of the slope to be undefined, it means that we are actually dividing by zero

For us to be dividing by zero, it actually means that there is no change in the x-value

The unchanging x-value is what has caused us to have an undefined slope value

Since line k and line g are parallel, their slopes are equal and the slope of k is undefined too

So the x-coordinates of the other points that lie on the line that we used in calculating the slope is -6
