Answer:

y = -3/7x + 5

Step-by-step explanation:

y2 - y1 / x2 - x1

2 - 8 / 7 - (-7)

-6/14

= -3/7

y = -3/7x + b

2 = -3/7(7) + b

2 = -3 + b

5 = b

Whatever, Inc., has a bond outstanding with a coupon rate of 5.74 percent and semiannual payments. The yield to maturity is 6.1

sveta [45]

Answer:

current market price of the bond is $958.73

Step-by-step explanation:

given data

coupon rate = 5.74 percent

yield to maturity = 6.1 percent

bond matures = 20 years

future value = $1,000

solution

we get here PMT that is

PMT = 1,000 × 5.74% ÷ 2 ...............1

PMT = $28.70

and Number of Periods is

NPER = 20 years × 2 = 40 semi-annual periods

and here Rate of interest will be = 6.1% ÷ 2 = 3.05%

and we use here formula that is

= -PV(Rate;NPER;PMT;FV;type)

so we get

current market price of the bond is $958.73

Two points on a line L are (5,2) and (7,-4). what is the slope of L

klemol [59]

Answer:

-3

Step-by-step explanation:

The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)

In this case we have:

(-4-(2))/(7-5)

(-6)/(2)

-3

Answer:

y = -4x-21

Step-by-step explanation:

Hi there!

We want to write an equation of the line that passes through (-4, -5) and is parallel to y=-4x-1.

Parallel lines have the same slopes. So let's find the slope of y=-4x-1.

The line is written in the form y=mx+b, where m is the slope and b is the y intercept.

As -4 is in the place of where m should be, -4 is the slope of y=-4x-1.

It's also the slope of the line parallel to that line.

Right now, what we know about the line parallel to y=-4x-1 is that the slope of it is 4 and it passes through the point (-4, -5).

We can substitute those values into the formula for point-slope form, which is $y-y_1=m(x-x_1)$ , where m is the slope and $(x_1, y_1)$ is a point.

We can label the values of everything to help us avoid confusion.

m=-4

$x_1=-4\\y_1=-5$

Now substitute those values into the formula. Note: the formula contains SUBTRACTION, and we have NEGATIVE numbers. Hence,

$y--5=-4(x--4)$

Now simplify.

$y+5=-4(x+4)$

On the right side, do the distributive property.

y+5=-4x-16

Subtract 5 from both sides.

<u>y=-4x-21</u>

Hope this helps!

(x^2-5x+6)+(3x^2-8x-2)

Zarrin [17]

Answer:

4x^2-13x+4

Step-by-step explanation:

1. Add together all like terms ( so x^2+3x^2=4x^2)

2. once you add all your like terms. order the numbers from biggest to smallest (4x^2'-13x+4)

*You'll know which is biggest by the exponent!

Hope this helps!!!!!
