You have a coupon for 20% off that can only be used in the physical store and a $20.00 off coupon that can only be used online. The sales tax of 7.5% only applies to the physical store. Shipping for the online store is a flat rate of $8.99 or free for purchases over $75.00. Using the information below, which way of purchasing would save you the most money?

Answer:

Online Ordering is better.

Step-by-step explanation:

So you now that you save 20% if you to physical store and you save $20 if you go to the online store.

Say you are spending 100 dollars at the store to make it easy. 20% of one hundred is $20 so that is the same amount of money.

Now let’s look at the taxes and shipping so at the physical store you have to pay taxes no matter what but online you only do it if you purchase is less than $75 and we have $80 ($100–$20=$80) so at the physical store you have some amount of Mandy that is more than $80 because of taxes but if you buy online it will be exactly $80.

Answer:

x^2 + 7x- 3/x - 3/x^2 -16

Step-by-step explanation:

Key:  ( ^ ) means exponent

= x^2 + 2x- 3/x -2x^2 + 5x- 3/x^2 -16

= x^2 - 2x^2 + 2x+5x - 3/x- 3/x^2 -16

= x^2 - 2x^2 = -x^2

=  -x^2 + 2x + 5x- 3/x- 3/x^2-16

As you see you add 2x and the 5x and got 7x

= Answer : <u>x^2 + 7x- 3/x - 3/x^2 -16</u>

A motorboat takes
vagabundo [1.1K]
Recall your d = rt, distance = rate * time

let's say the boat's rate is "b" in still water, and the current's rate is "c"

as the boat goes upstream, is not really going "b" fast, the water is not still anyway, is going much slower, is going " b - c ", because the current's rate is eroding speed because is going against the current.

as the boat goes downstream, is not going "b" fast either, is going faster, is going " b + c " fast, because is going downstream and thus with the current and the current is adding speed to it.  notice, it takes longer going up, 5hrs, then coming down, 3hrs, same 150 on each way.

\bf \begin{array}{llll}&#10;&distance&rate&time\\&#10;&-----&-----&-----\\&#10;upstream&150&b-r&5\\&#10;downstream&150&b+r&3&#10;\end{array}&#10;\\\\\\&#10;&#10;\begin{cases}&#10;150=(b-r)5\\&#10;\qquad \frac{150}{5}=b-r\\&#10;\qquad 30=b-r\\&#10;\qquad 30+r=\boxed{b}\\&#10;150=(b+r)3\\&#10;\qquad \frac{150}{3}=b+r\\&#10;\qquad 50=b+r\\&#10;\qquad 50=\boxed{30+r}+r&#10;\end{cases}

solve for "r"

what's the boat's rate? well, 30+r = b

2k^2 + 9k = -7 using quadratic equation
Pepsi [2]

Answer:(k+1)(2K+7)

Step-by-step explanation:

Using the quadratic formula

X=-b±-√b^2-4ac/2a

ax^2+bx+c=0

2k^2+9k+7=0

In this case a=2,b=9,c=7

-9+-√9^2-4(2)(7)/2(2)

(-9+√25)/4=-9+5/4=-1

(-9-√25)/4=-14/4 =-7/2

X=-1,X=-7/2

So (K+1)(k+7/2)

So (k+1)(2k+7)
