Answer:
x= original price

% off= 20%

Sale $= $680

STEP 1:

Find discount amount

Discount Amount= % off * Original $

= 20% * x

change % to decimal (% ÷ 100)

= 0.20 * x

= 0.20x

STEP 2:

Find sale price

Sale Price= Original $ - Discount

= x - 0.20x

= 0.80x

STEP 3:

Sale= $680= 0.80x

Solve for x

$680= 0.80x

divide both sides by 0.80

$680/0.80= x

$850= x

ANSWER: The original price is $850

Hope this helps! :)

The productivity of workers at a shoe factory (in pairs of shoes per hour) can be modeled using the function p(h) = -2/7h + 5, where h is the number of hours. If a worker must create at least 3 pairs of shoes per hour for the company to be profitable, how long should the worker's shift be?

So firstly, we have to determine what 6% of $12.50 is. You can do this by multiplying 12.50 and 6% (or 0.06 in decimal form) to get 0.75, or 75 cents. 75 cents is your 6% sales tax.

Next, add up 12.50 and 0.75 to get $13.25. **$13.25 is the total cost of the item.**

**Answer:**

13.25

To find the number of non-defective chips, we simply use this equation:

2,000 * 4/5

8000/5

Now you simply divide:

1600

**1600 chips aren't defective**

2,000 * 4/5

8000/5

Now you simply divide:

1600

1a. Gabriella uses these services:

Checking (she has an account)

Debit card

1b. At A+ Bank, Gabriella's monthly charges will be

$1 (for checking) + $2.50 (for debit card) = $3.50

At NextGen Bank, Gabriella's monthly charges will be

0 (for checking) + $0.50*20 (for debit card) = $10.00

1c. A+ Bank is a better deal for Gabriella. The fixed fees there are lower than the variable fee at NextGen Bank because she uses her debit card so much.

sin 2x sin x + cos x= 0

Use the double angle identity:

sin(2*x*) = 2 sin(*x*) cos(*x*)

Now rewrite

sin(2*x*) sin(*x*) + cos(*x*) = 0

as

2 sin²(*x*) cos(*x*) + cos(*x*) = 0

Factor out cos(*x*) :

cos(*x*) (2 sin²(*x*) + 1) = 0

Consider the two cases,

cos(*x*) = 0 OR 2 sin²(*x*) + 1 = 0

Solve for cos(*x*) and sin²(*x*) :

cos(*x*) = 0 OR sin²(*x*) = -1/2

Squaring a real number always gives a non-negative number, so the second case doesn't offer any real solutions. We're left with

cos(*x*) = 0

Cosine is zero for odd multiples of *π*/2, so we have

*x*** = (2***n*** + 1) ***π***/2**

where *n* is any integer.

**Answer:**

The graph of f(x) shifts 5 units right and 9 units down to graph g(x).

**Step-by-step explanation:**

The general form of the parabola is

Where, (h,k) is the vertex of the parabola and a is stretch factor.

The parent function is

The vertex of the parabola is (0,0).

The given function is

The vertex of the parabola is (5,-9).

**The vertex of the parabola shifts from (0,0) to (5,-9), therefore the graph of f(x) shifts 5 units right and 9 units down to graph g(x).**

To graph the function g(x) = (x – 5)2 – 9, shift the graph of f(x) = x2 ✔ right

5 units and ✔ down 9 units.

5 units and ✔ down 9 units.
