Answer: (below)

Step-by-step explanation:

y = 2x + 1

slope = 2

y-int = (0, 1)

y = 3x - 1

slope = 3

y-int = (0, -1)

y = 4x

slope = 4

y-int = (0, 0)

y = -3x - 1

slope = -3

y-int = (0, -1)

y = -x - 4

slope = -1

y-int = (0, -4)

y = (2/5)x - 1

slope = 2/5

y-int = (0, -1)

A credit card had an APR of 15.98% all of last year, and compounded interest daily. What was the credit card's effective interes

zimovet [89]

Answer:

Option(B) is the correct answer to the given question.

Step by Step Explanation

We know that

$A\ =\ P \ *(\ 1+\ \frac{r}{n} \ ) ^{nt}$

Here A=amount

r=15.98%=0.1598

n=365

t=1

Putting these values into the equation

$A\ =\ P \ *(\ 1+\ \frac{0.1598}{365} \ ) ^{365}$

$A\ =\ P \ *(\ 1+\ 0.000437) ^\ { 365}$

$A\ =\ P \ *(\ 1.000437 ) ^{365}$

$A\ =1.17288 P$

Now we find the interest

I= $1.17288P\ -P\\=\ 0.17288P\\\ ~ 0.1720P$

Therefore effective interest rate of the last year can be determined by

$\frac{0.1720P}{P}$

=0.1720 *100

=17.20%

On average, Tammy is able to read 2 chapters in her book each week. How many weeks will it take Tammy to read 5 1/2 chapters?

anastassius [24]

2 3/4 weeks because 2 a week then another week is 4 then add a 1/2 because it’s 5 then add a 4th because there’s another 1/2 so you get 2 and 3/4 weeks

A man has $290,000 invested in three properties. One earns 12%, one 10% and one 8%. His annual income from the properties is $27

Archy [21]

Answer:

Step-by-step explanation:

let amount invested at 12%=x

amount invested in 10 %=y

amount invested in 8 %=z

z=2x

x+y+z=290,000

x+y+2x=290,000

3x+y=290,000

multiply by 5

15x+5y=1,450,000 ... (1)

12/100 x+10/100 y+8/100 z=27,600

12x+10 y+8z=2,760,000

6x+5y+4z=1,380,000

6x+5y+4(2x)=1,380,000

14x+5y=1,380,000 ... (2)

(1)-(2) gives

x=1,450,000-1,380,000=70,000

z=2(70,000)=140,000

70,000+y+140,000=290,000

y+210,000=290,000

y=290,000-210,000=80,000

invested in 12 %=$ 70,000

invested in 10 %=$ 80,000

invested in 8 %=$ 140,000

(b)

annual income from 12 %=12/100 ×70,000= $8,400

annual income from 10 % =10/100×80,000=$ 9,600

annual income from 8 %=8/100×140,000= $11,200
