Answer: B

Answer:

B. <em>y</em> = -3<em>x</em>

Step-by-step explanation:

By reviewing the options:

A. <em>y </em>=<em> </em>3<em>x</em>

when <em>x</em> = -3 --> <em>y</em> = 3(-3) = -9 and the table of values says 9, so this can't be the correct answer.

B. <em>Y </em>= -3<em>x</em>

when <em>x</em> = -3 --> <em>y</em> = -3(-3) = 9 wich is the value of the table, so we check for the next <em>x</em> value.

when <em>x</em> = -1 --> <em>y</em> = -3(-1) = 3 wich is the value of the table, so we check for the next <em>x</em> value.

when <em>x</em> = 0 --> <em>y</em> = -3(0) = 0 wich is the value of the table, so we check for the next <em>x</em> value.

when <em>x</em> = 3 --> <em>y</em> = -3(3) = -9 wich is the value of the table, so we have found the correct answer.

Since B. is valid for every value of <em>x</em> on the thable <em>y</em> = -3<em>x</em> is the answer.

serg [7]
Answer is: 50.4%. You have to take 30% off of 72%. Easiest way is to find 10% of 72 (7.2) and multiply that by 3 (=21.6). Then minus this off the original price (72 - 21.6 = 50.4)

What's the hight of a million pennies
TiliK225 [7]

The thickness of a brand new US penny that hasn't been
worn down is 1.52 millimeters.

If you have a million pennies, there are many ways to arrange them.
You can pile them all in one pile, or shovel them into many piles, or
stack them up in any number of stacks up to a half-million stacks
with two pennies in each stack, or try somehow to stack them all up
in one stack that's a million thicknesses high.

Any stack with 'n' pennies in the stack is  1.52n millimeters high.

If you somehow succeed in stacking all million of them in one stack,
then the height of that stack would be . . .

       (1,000,000) x (1.52 mm) =  1,520,000 millimeters
                                                         152,000 centimeters
                                                             1,520 meters
                                                               1.52 kilometers

                                            (about 59,842.5 inches
                                                          4,986.9 feet
                                                         1,662.3 yards
                                                               7.56 furlongs
                                                            0.944 mile
                                                                  all rounded)
