Answer:

$y=3x-5$

Step-by-step explanation:

$m=10-1/5-2$

$m=9/3$

$m=3$

$y=3x+b$

$x=2, y=1$

$1=3(2)+b$

$1=6+b$

$-5=b$

$y=3x-5$

I’m pretty sure you can first do 10% at a time which you can round to 13 which is 3 so 3 plus 3 then add tax

Which equation is the inverse of y = 7x2 – 10?

MrRissso [65]

we have

$y=7x^{2}-10$

To find the inverse

Step 1

Exchanges the variables, x for y and y for x

$x=7y^{2}-10$

Step 2

Isolate the variable y

$x=7y^{2}-10$

$7y^{2}=x+10$

$y^{2}= \frac{x+10}{7}$

Square Root both sides

$y=(+/-)\sqrt{\frac{x+10}{7}}$

Step 3

Let

$f(x)^{-1}=y$

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

therefore

<u>the answer is</u>

The inverse is

$f(x)^{-1}=(+/-)\sqrt{\frac{x+10}{7}}$

Joanne's Dress Shop received an invoice dated July 25 for $1,400, with terms of 2/10, 1/15, n/60. On August 8, Joanne's Dress Sh

ss7ja [257]

The actual amount that should be credited is $757.58.

<u>Solution:</u>

Given that,

2% Discount if paid in 10 days.

1% Discount if paid in 15 days, (but greater that 10 days)

Net due in 60 days.

That is,

$\bold{1400\times0.98 = 1372}$ will close the acount on days 1-10

$\bold{1400\times0.99 = 1386}$ will close the acount on days 11-15

And August 8 is Day 15 and falls under the 1% discount rule.

Therefore, we have to divide the partial payment by the complement of the discount rate.

$\bold{\Rightarrow\frac{750}{0.99} = 757.58}$ from the balance, and $\bold{1400.00 - 757.58 = 642.42}$ is due by day 60.
