Is the opposite of an opposite number always going to be positive?

Answers

Answer 1

Answer: No, the opposite of an opposite will not always be positive. the opposite of -4 is 4, and the opposite of that is -4, so the opposite of the opposite of the number -4 is -4, which is not positive. On the other hand, it CAN be positive. The opposite of 7 is -7, and opposite of that is 7, which is positive.

Answer 2

Answer: yes it is because if you reflect for a min, the opposite (which is a negative) of the opposite is always going to be a positive.

Answer:

Step-by-step explanation:

each zero of the function will have a factor of (x - x₀)

h(x) = a(x + 3)(x + 2)(x - 1)

h(x) = a(x + 3)(x² + x - 2)

h(x) = a(x³ + 4x² + x - 6)

or the third option works if a = 1

however this equation gives us the points (0, -6) and (-1. -4), so "a" must be -2

h(x) = -2x³ - 8x² - 2x + 12

to fit ALL of the given points as it fits the three zeros and also h(0) and h(-1) so I guess that is why the given group is a partial set of solution sets

Luis is doing his math homework. He has 30 problems in all. After an hour, he only has 1/6 of those problems left. How many problems does he have left?

Answers

Answer:

$\huge\boxed{5}$

Step-by-step explanation:

Luis has 30 problems and after one hour, $(1)/(6)$ of those problems are left. This means that the total number of problems left will be $30 \cdot (1)/(6)$ .

Multiplying by a fraction is the same as dividing by a whole. The denominator of $(1)/(6)$ is 6, so we can divide 30 by 6.

$30 / 6 = 5$

Hope this helped!

Answer: 25

Step-by-step explanation: 1/6 of 30 is 5, so 30 minus 5 equals 25.

Which expression is equivalent to the given expression? 2x - 11x-6 A. 2(x – 3) (x + 1) B. (2x + 3)(x- 2) C. (2x+ 1)(x- 6) D. 2(x + 3)(x- 2)

Answers

Answer:

Option C. (2x + 1)(x - 6)

Step-by-step explanation:

To know which option is equivalent to 2x² - 11x - 6, we shall simplify the expression as follow:

2x² - 11x - 6

Multiply the 1st term (i.e 2x²) and last term (i.e - 6) together. This is illustrated below:

2x² × - 6 = - 12x²

Next, find two factors of - 12x² such that when we add them together, it will result to the 2nd term (i.e - 11x) in the expression above.

The factors are x and - 12x

Next, replace - 11x with x and - 12x in the expression 2x² - 11x - 6 as shown below:

2x² - 11x - 6

2x² + x - 12x - 6

Next, we shall factorise the expression 2x² + x - 12x - 6 as follow:

2x² + x - 12x - 6

x(2x + 1) - 6(2x + 1)

(2x + 1)(x - 6)

Thus,

2x² - 11x - 6 is equivalent to (2x + 1)(x - 6)

Final answer:

The simplified form of the given expression is -9x - 6. Unfortunately, none of the provided options A, B, C or D is equivalent to this expression when simplified.

Explanation:

This question is centered around the idea of finding an expression that is equivalent to the given. First step is to simplify the given expression, which is 2x - 11x - 6. To simplify, combine like terms that leads to -9x - 6.

Next, we look at each of the provided options to find which one would simplify to the same expression:

A. 2 (x - 3) (x + 1) simplifies to 2x^2 -4x - 6 which isn't equal to -9x - 6

B. (2x + 3) (x - 2) simplifies to 2x^2-4x -6, which again doesn't match our given expression.

C. (2x + 1) (x - 6) simplifies to 2x^2 - 12x - 1, which doesn't match as well.

D. 2 (x + 3) (x - 2) simplifies to 2x^2 -2x -12, yet another mismatch.

With all options examined, none of the provided expressions are equivalent to the original expression of -9x - 6.
