You can tell b (y=mx+b) by the number it intersects on the y axis. So the line goes through 8 on the y axis. Therefore, we can eliminate D. The line is going to the left, so it’s negative, meaning we can eliminate C. The answer is A because the slope is -1/4.

Consider the expression: (x + 3)•(y + 1)•(x + 2)
emmainna [20.7K]

Answer:

Step-by-step explanation:

First we multiply x through (y+1). This equals xy +x.

Second we take 3 through (y+1). This equals 3y+3.

Next we take xy + x through (x+2). This equals 2x squared, y + 2x squared.

Fourth we take 3y+3 through (x+2). This equals 6xy + 6x.

A bill for $100 is purchased for $96 three months before it is due. Find: 1 The nominal rate of discount convertible quarterly e
Dovator [93]

Answer:

1. The nominal interest rate  is 16.67%

2. The effective interest rate is 4.17%

Step-by-step explanation:

1.firstly we use the information given:

face value of bill is$100 which is denoted by Fv below.

$96 is the present value Pv of the bill denoted below.

thereafter we have n the number of periods of compounding which is 1 period.

we use the following formula for this problem to find i the nominal interest rate:

Fv = Pv(1+i)^n

then we substitute the above mentioned values.

$100 = $96 ( 1+i/m)^1 divide both sides by $96

(100/96) = 1+ i/4   then subtract both sides by 1

(100/96)- 1 = i/4

0.0416666666667 = i/4 then multiply by 4 both sides as this was compounded quarterly so four times a year then multiply by 100 for percentage.

16.67% = i which is the nominal interest rate

2. ieffective = (1+i nominal/n)^n  -1

ieffective= (1+16.67%/4)^1 - 1

ieffective = 4.17%

Hitman42 [59]
<span>I honestly believe that not everyone uses their phones during meetings or classes unless they are bored or simply searching for more information on the topic. These days cell phone devices are used by teachers and those conducting meetings. I've even seen preacher's pull up the Bible from their phones. So if fewer than 44 people use them that's actually good.</span>

Find 4 consecutive even integers where the product of the two smaller numbers is 72 less than the product of the two larger numb
WARRIOR [948]

Answer: 6, 8, 10, 12

Step-by-step explanation:

Given that x is the number, the 4 numbers would be

x, x + 2, x + 4, x + 6

so the two smallest numbers would be x and x + 2

and the two largest numbers would be x+4 and x+6

now set up an equation

x(x+2) = (x+4)(x+6) - 72

now FOIL

x^2 + 2x = x^2 + 6x + 4x + 24 - 72

combine like terms

x^2 + 2x = x^2 + 10x -48

subtract x^2 from both sides

2x = 10x - 48

subtract 2x from both sides

0 = 8x - 48

add 48 to both sides

48 = 8x

divide both sides by 8

6 = x

so the four numbers, x, x+2, x+4, and x+6 when you plug in x are equal to

6, 8, 10, 12
