Write an equation for the line that passes through (- 3, 5) and is parallel to y = - 6x + 1.
soldier1979 [14.2K]

Answer:

y-5 = -6(x+3) OR y = -6x-13

Step-by-step explanation:

Let's use slope-intercept form to solve this problem.

Slope intercept form is the following:

y-y1 = m(x-x1)

x1 and y1 are given by the point in the problem.

x1 = -3, y1 = 5.

m is given by the equation in the problem. Lines that are parallel have the same slope. Thus,

m = -6.

If we plug these values into the equation for slope intercept form, we get the following:

y-5 = -6(x-(-3)) which becomes y-5 = -6(x+3)

This is an acceptable answer to the problem. However, point-slope form is also a way it can be written.

y-5 = -6x-18

y = -6x-13

A portfolio has a E[r] of 12% and a std deviation of 18%. T-Bills return 7%. What is the maximum level of risk aversion (A) for
solniwko [45]
<h2>The required "option D) 3.09" is correct.</h2>

Step-by-step explanation:

Given,

A portfolio has a E[r] = 12 %, and

A standard deviation (\sigma) = 18 %

We know that,

Specify utility by U = E(r) – 0.5A\sigma^2

U = 0.12– 0.5(A) × 0.18^2

= 0.12 - 0.5  ×  A × 0.0162

In order for the risky portfolio to be preferred to bills,

The following condition must have:

0.12 – 0.0162A > 0.07

⇒ A < \dfrac{0.05}{0.0162} = 3.09

A must be less than 3.09 for the risky portfolio to be preferred to bills.

Thus, the required "option D) 3.09" is correct.

What is the slope of the line that passes through the points (1, 7) and (–4, –8)?
const2013 [10]

Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :

\spadesuit\; Slope(m) = \frac{y_1 - y_2}{x_1 - x_2}

Given Points are (1 , 7) and (-4 , -8)

here x₁ = 1 and x₂ = -4 and y₁ = 7 and y₂ = -8

\spadesuit\; Slope(m) = \frac{7 + 8}{1 + 4} = \frac{15}{5} = 3

The regular price of a scooter is $65.50. It is on sale for $52.40. What is the percent
kherson [118]

Answer:

20%

Step-by-step explanation:

First we find the actual dollar amount of the discount.

$65.50 - $52.40 = $13.10

Now we need to find what percent of $65.50 is $13.10.

To find what percent a part is of the whole, divide the part by the whole and multiply by 100%.

percent = part/whole * 100%

percent = $13.10/$65.50 * 100% = 20%

Answer: 20%
