Given the sequence 12, 9, 6, 3,........ where x = 0, 1, 2......,

Nitella [24]

Answer:

f(x) = -3x + 12

Step-by-step explanation:

The chart could be represented like this:

x y

0 12

1 9

2 6

3 3

Suppose that f(x) = y

And substitute x values.

y = -3x + 12

"x = 0"

y = -3(0) + 12

y = 0 + 12

y = 12

"x = 3"

y = -3(3) + 12

y = -9 + 12

y = 3

From the results, it corresponds to the function.

Yu Xing paid 3.60 dollar for 2 pens after a 10 percent discount .What was the usual price of 1 pen.

notka56 [123]

Answer:

2 $

Step-by-step explanation:

let the original price be x

price after 10% discount = 3.60$

$x - \frac{10}{100} \times x = 3.60$

$\frac{100x - 10x}{100} = 3.60 \\ \frac{90x}{100} = 3.60 \\ 9x = 36 \\ x = 4$

The original price of 2 pens is 4$

original price of one pen = 4/ 2

= 2 $
