F(x) > 0 over the intervals (-∞, -0.7) and (0.76, 2.5).
F(x) < 0 over the intervals (-0.7, 0.76) and (2.5, ∞).
F(x) > 0 over the intervals (-0.7, 0.76) and (0.76, ∞).

Which Statement Is True About The Graphed Function? F(x) &lt; 0 Over The Intervals (-, -0.7) And (0.76,

Answers

Answer 1
Choice A) True. The f(x) portion is below the x axis on the interval (-infinity, -0.7) and on the interval (0.76, 2.5)

Choice B) False. This is a complete contradiction of choice A. 

Choice C) False. The portion of f(x) on the interval (-0.7, 0.76) is above the x axis.

Choice D) False. The portion of f(x) is above the x axis on the interval (-0.7,0.76); however, f(x) is below the x axis on the interval (0.76, 2.5). See choice A.

---------------------------------------

In summary, the final answer is choice A

Answer 2

Answer: A. F(x) < 0 over the intervals (-∞, -0.7) and (0.76, 2.5).

Write an integer whose absolute value is greater than itself

Answers

Any negative number is correct because a negative number's absolute value will be positive. Which automatically makes it larger than the negative number. For example: -1 < |-1|

All negative numbers are integers whose absolute value is greater than itself for example-3.

What is absolute value?

Absolute values are the value of any digit without considering the sign.

So all negative values will be considered positive for absolute value.

For example, the absolute value of -2 will be 2 and the absolute value of -7 will be 7.

Absolute value is value without considering sign so all negative values will be considered positive.

For example -3 → | -3 | = 3 and 3 > -3

All positive values will be greater than their negative value.

Hence "All negative numbers are integers whose absolute value is greater than itself".

A. Multiplication comes before division because in PEMDAS the M comes before D.

Answers

Multiplication and division have the precedence. We know which comes first because we go from left to right and which ever comes first is done first.

Students who use PEMDAS often think that multiplication must come before division but that's not necessarily the case. If division appears before multiplication when your reading the problem from left to right, do your division first and then move on to your multiplication.

what percent of 92 is 69

Answers

75% of 92 is 69, hope this helps

The number 69 is 75 % or 75 percentage of the number 92

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage be represented as A

Let the first number be n₁ = 92

Let the second number be n₂ = 69

And , the percentage value of 69 of the number 92 is given by

n₂ = ( A / 100 ) x 92

On simplifying , we get

69 = ( A / 100 ) x 92

Multiply by 100 on both sides , we get

6900 = 92A

Divide by 92 on both sides , we get

A = 6900 / 92

A = 75 %

Therefore , the value of A is 75 %

Hence , the percentage value of 69 of the number 92 is 75 %
