James has a balance of $1700 on a credit card with an APR of 18.7%, compounded monthly. About how much will he save in interest

miss Akunina [59]

Answer:

$121.51

Step-by-step explanation:

At 18.7%, the monthly multiplier is 1+.187/12, so for the year, James' balance is multiplied by (1+.187/12)^12 ≈ 1.2038899

At 12.5%, the monthly multiplier is 1+.125/12, so for the year, James' balance is multiplied by (1+.125/12)^12 ≈ 1.1324161

The difference in these multipliers is ...

1.2038899 -1.13241605 = 0.0714739

so James' savings is ...

$1700 × 0.0714739 ≈ $121.51

What is the slope of the line y+4 = 3(x+6)

Akimi4 [234]

Answer:

Step-by-step explanation:

First you gotta take the equation and bring it to the following form:

$y = ax + b$

The slope of the line is the coefficient of x, a.

In other words:

$y + 4 = 3(x + 6) \\ y + 4 = 3x + 18 \\ y = 3x + 18 - 4 \\ y = 3x + 14$

So, as we can see, the number infront of x is 3. That is to say that the slope of this line is equal to 3.

A2+b2 = C2solve for a

lesantik [10]

$a^2+b*2=c^2$

$a^2+2b=c^2

$ $\text{Regroup terms}$

$a^2=c^2-2b
$ $\text{Subtract 2b from both sides}$

$a=\pm \sqrt{c^2-2b}$ $\text{Take the square root of both sides}$
