Explain why the expression below always has the same value, no matter what number other than zero you choose for p.

Natasha2012 [34]

Answer and explanation:

The expression P-2P+3P-4P cannot have the same values for different values of P. Let us illustrate this by substituting different values of P in the expression:

If P= 2

Substitute P=2 in the expression

2-2×2+3×2-4×2

=2-4+6-8

=-4

If P= 3

Substitute P=3 in the expression

3-2×3+3×3-4×3

=3-6+9-12

=-6

If P = 1

Substitute P=1 in the expression

1-2×1+3×1-4×1

= 1-2+3-4

= -2

If P = -2

Substitute P=1 in the expression

-2-2×-2+3×-2-4×-2

= -2+4-6+8

Therefore we can see from the above that the expression has different values for different values of P

Satchi found a used bookstore that sells pre-owned videos and CDs. Videos cost $9 each, and CDs cost $7 each. Satchi can spend n

Yuliya22 [10]

Hello!

Let's use 'v' for videos and 'c' for CDs.

The inequality that would represent this situation would be:

9v + 7c < 35

No, Satchi does NOT have enough money to buy 2 videos and 3 CDs.

????????????????????????????

Answer: See below.

Step-by-step explanation:

Let's go number by number.

Rational pretty much means you can put it into a fraction of whole numbers.

The first number is -81,572.

This number is rational because it can be put into a fraction ( $\frac{-81572}{1}$ ) that is made up of whole numbers.

The second number is $\sqrt{11}$ .

This number is irrational because it cannot be put into a fraction of whole numbers.
Keep in mind that most squareroots are irrational. Especially those that don't equal a whole number.

The third number is 5.636336333

There is a pattern so the number is rational.
Usually a pattrn means it can be put into a fraction.

The fourth number is $\sqrt{16}$ . This equals 4 if you solve it out.

Since we just get 4, that certainly can be put into a fraction of whole numbers, so this is rational.
