1 + 4x = -5 + 7x

-4x - 4x

1 = -5 + 3x

+5 +5

If a is a negative number, then a(1/a) is equal to -1. If a is a negative number and b is a negative number, then product ab is

Firdavs [7]

Both claims are false. In fact, $a$ and $\frac{1}{a}$ are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that

$a \cdot \dfrac{1}{a} = 1 \quad\forall a \in \mathbb{R}$

So, it doesn't matter if $a$ is positive or negative: the multiplication of one number and its inverse will always be 1: for example,

$(-2) \cdot \dfrac{1}{-2} = \dfrac{-2}{-2} = 1$

Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:

$(+) \cdot (+) = (+)$
$(+) \cdot (-) = (-)$
$(-) \cdot (+) = (-)$
$(-) \cdot (-) = (+)$

So, the multiplication of two negative numbers is a positive number.

What is the period of the graph of y = 5cos(6x – 1) + 3? O A.

evablogger [386]

Step-by-step explanation:

The coefficent of the x variable is b.

The formula for the period is

$\frac{2\pi}{ |b| }$

Here, b is 6 so we have

$\frac{2\pi}{ |6| } = \frac{\pi}{3}$

So the period is pi/3, or 60 degrees

May someone help me out with this question please

You would have 60 different types of pens with this brand. You need to multiply 12 and 5 (because you have 12 different colors for every type of tip, so you have 5 groups of 12).
