Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

6x + 10y = 8 ( subtract 6x from both sides )

10y = - 6x + 8 ( divide each term by 10 )

y = - $\frac{6}{10}$ x + $\frac{8}{10}$ = - $\frac{3}{5}$ x 6 + $\frac{4}{5}$ ← in slope- intercept form

with slope m = - $\frac{3}{5}$ → C

An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $5990 and her st

GenaCL600 [577]

Answer: 14.38%

Step-by-step explanation:

Worth of stock in Company A = $5990

Percent decrease = 20%

New worth = $5990 - (20% × $5990)

= $5990 - (0.2 × $5990)

= $5990 - $1198

= $4972

Worth of stock in Company B = $2450

Percent decrease = 8%

New worth = $2450 - (8% × $2450)

= $2450 - (0.08 × $2450)

= $2450 - $196

= $2254

Previous total worth = $5990 + $2450

= $8440

Total worth = $4972 + $2254

= $7226

The total percentage decrease in the investor's stock account will be:

= [($8440 - $7226) / $8440] × 100

=( $1214 / $8440) × 100

= 0.1438 × 100

= 14.38%

what is the value of the discriminant of the quadratic equation -2x^2 -8x+8 and what does it value mean about the number about t

sweet-ann [11.9K]

Answer:

Step-by-step explanation:

It is been considered that Discriminant is calculated by the following formula:

D = b*b - 4 * a * c

In order to simplify the calculations we can divide all the numbers by 2 and we will have the same quadratic equation:

-x^2 -4x+4=0

and as usual quadratic equation is presented as the following:

ax^2 - bx + c = 0

so in our case a = -1; b = -4; c = 4;

Then D = -4*4 -4*(-1) * 4 = -16+16 = 0

I am not quite understanding the following phrase:

"and what does it value mean about the number about the number"

but if the question was in regards of the following number '-2x^2' so number ^2 is actually the value of power so 'x' is multiplied on it is own and this equation basically means the following:

-2x^2 = -2 * (x) * (x)

Use the present value formula to determine the amount to be invested now, or the present value needed.

Vladimir79 [104]

Answer:

The value needed now is $102,296.60

Step-by-step explanation:

Here, we want to calculate the present value needed.

We shall be using the formula for compound interest here

Mathematically;

A = I(1 + r/n)^nt

According to the question;

I is the initial amount which is what we want to calculate

A is the accumulated amount with interest = 140,000

r is the interest rate = 8% = 8/100 = 0.08

n is the number of times interest is compounded which is 4, since it is quarterly

t is the number of years = 2

Substituting these values, we have ;

140,000 = I(1 + 0.08/2)^(4 * 2)

140,000 = I(1.04)^8

I = 140,000/(1.04)^8

I = 102,296.62870027774

Which is I = $102,296.60 to the nearest cent
