Answer:

y + 3 = -1(x-1)

Step-by-step explanation:

sub (1, -3) and slope = -1:

y - (-3) = -1(x - 1)

That depends on whether you want to round to the nearest ten, the nearest
hundred, or the nearest thousand. Each of those answers is different.

A consultant has three sources of income—from teaching short courses, from selling computer software, and from advising on proje

Amanda [17]

Answer:

Mean = $79,000

Standard deviation = $25,000

Step-by-step explanation:

Data provided in the question:

Expected annual incomes:

From teaching short courses = $7,000

From selling computer software = $22,000

From advising on projects = $50,000

Standard deviation:

teaching short courses = $3,000

selling computer software = $4,000

advising on projects = $18,000

Now,

it is given that the events are independent

therefore,

Mean = ∑(Expected annual income)

Mean = $7,000 + $22,000 + $50,000

Mean = $79,000

also,

Standard deviation = ∑(standard deviation)

Standard deviation = $3,000 + $4,000 + $18,000 = $25,000

Write the equation of a line in slope-intercept form that is parallel to the given line and passes through the point (12,-25).

lina2011 [118]

Answer:

$m_1 = m_2 = \frac{1}{4}$

And then since the new equation have the following form:

$y = m_2 x +b$

We can use the point given (x=12, y = -25) in order to find the intercept with this equation:

$-25 = \frac{1}{4} (12) +b$

And solving for the intercept b we got:

$-25 = 3 +b$

We subtract in both sides 3 and we got:

$b = -25-3 = -28$

And our final equation who satisfy the condition given is:

$y= \frac{1}{4} x -28$

Step-by-step explanation:

For this case we have the following equation given:

$y = \frac{1}{4} x + 2$

And we want to find an equation of a line parallel to the given function and this case we need to satisfy this condition:

$m_1 = m_2 = \frac{1}{4}$

And then since the new equation have the following form:

$y = m_2 x +b$

We can use the point given (x=12, y = -25) in order to find the intercept with this equation:

$-25 = \frac{1}{4} (12) +b$

And solving for the intercept b we got:

$-25 = 3 +b$

We subtract in both sides 3 and we got:

$b = -25-3 = -28$

And our final equation who satisfy the condition given is:

$y= \frac{1}{4} x -28$
