Answer:

v = - 1

Step-by-step explanation:

3 = - 2v - v

3 = - 3v | ×(-)

What does it mean to say we have a base ten system? Be specific. Use examples.
NeTakaya

Answer:

This means that the decimal system is responsible for representing quantities using ten different digits.

Step-by-step explanation:

This means that the decimal system is responsible for representing quantities using ten different digits: 0 (zero), 1 (one), 2 (two), 3 (three), 4 (four), 5 (five ), 6 (six), 7 (seven), 8 (eight) and 9 (nine).

The digits acquire their value according to the relative position they occupy. This position, in turn, depends on the base in question. It has the powers of the number ten as a base. Thus: 10 raised to 0 is equal to 1; 10 raised to 1 is equal to 10; 10 raised to 2 equals 100; etc.

The number 123, for example, has three figures. In the decimal system, it is constructed as follows, respecting the corresponding positions:

(1 x 10 raised to 2) + (2 x 10 raised to 1) + (3 x 10 raised to 0)

(1 x 100) + (2 x 10) + (3 x 1)

100 + 20 + 3

123

As you can see, from right to left, the first place corresponds to the unit (10 raised to 0), the second place corresponds to the ten (10 raised to 1) and the third place corresponds to the hundred (10 raised to 2 ).

Hope this helps!

1. The 2nd number line represents the inequality.

Explanation:

In words, the inequality reads "negative six is less than x, which is less than or equal to two". On the number line, the open circle at negative six means that -6 is not a solution to the inequality: -6 < x. The point at positive two means that positive two is a solution to the inequality: x ≤ 2. Therefore, all numbers greater than -6 and less than or equal to +2 are solutions to the inequality. This is shown on the second number line.

2. False

Explanation:

In words, the inequality reads "x is less than negative five". This means that all numbers less than -5 are solutions to the inequality. Positive four is not less than negative five, so it is not a solution to the inequality.

3. x > 2

Explanation:

To solve the inequality, we have to move all the terms that do not contain x to one side. This inequality is simple because it only requires one step: subtraction.

Solve for x: x + 3 > 5

1. Subtract 3 from both sides to get x by itself:

x + 3 - 3 > 5 - 3

2. Simplify

x > 2

Sinx(cscx-sinx)=cos^2x
Yuri [45]

\bf sin(x)[csc(x)-sin(x)]~~=~~cos^2(x) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ sin(x)\left[\cfrac{1}{sin(x)}-\cfrac{sin(x)}{1} \right]\implies \underline{sin(x)}\left[\cfrac{1-sin^2(x)}{\underline{sin(x)}} \right] \\\\\\ 1-sin^2(x)\implies cos^2(x)


recall again, sin²(θ) + cos²(θ) = 1.
