Answer:

a < 0  <em> </em><em>False</em>

|a| > 0 <em> </em><em>True</em>

|a|=0  <em>False</em>

________________________________________________

<em>a </em>is on the right side of 0,

which means <em>a</em> is positive.

The absolute value is the distance to zero (always positive)

Which means the absolute value of<em> a</em> is also positive.

a < 0   is wrong because a is positive

|a| > 0  is correct because a is larger than 0

|a|=0  is wrong because a ≠ 0

Hope this helps :)

Given that f(x) = x2 + 5x – 14 and g(x) = x + 7, find (fºg)(x) and express
mel-nik [20]

Answer:

We get \mathbf{(fog)(x)=x^3+12x^2+21x-98}

Step-by-step explanation:

We are given:

f(x) = x^2 + 5x - 14 \\ g(x) = x + 7

We need to find (f o g)(x)

We know that: (fog)(x)=f(x)\times g(x)

We multiply the both terms i.e. f(x) and g(x) to get our answer.

(fog)(x)\\=f(x)\times g(x)\\=(x^2+5x-14)(x+7)\\=(x^2+5x-14)(x)+(x^2+5x-14)(7)\\=x^3+5x^2-14x+7x^2+35x-98\\Combining\:like\:terms:\\=x^3+5x^2+7x^2-14x+35x-105\\=x^3+12x^2+21x-98

So, we get \mathbf{(fog)(x)=x^3+12x^2+21x-98}

Can any negative integer be greater than a positive integer explain
Keith_Richards [23]

No, it is impossible. Intuitively, a negative number sits at the left of 0 on the number line, and a positive number sits at the right of 0 on the number line. And a number x is greater than another number y if x sits at the right of y on the number line. So, every positive number is greater than any negative number.

Also, by definition, a positive number is greater than 0, and a negative number is smaller than zero. So, if x is positive and y is negative, you have

y < 0 < x

and since the relation of order "<" is transitive, this implies

y < x

C) 0.2(x + 5) + 1 = 7​
swat32

Answer:

x = 25

Step-by-step explanation:

Given

0.2(x + 5) + 1 = 7 ( subtract 1 from both sides )

0.2(x + 5) = 6 ( divide both sides by 0.2 )

x + 5 = 30 ( subtract 5 from both sides )

x = 25

An alarming number of U.S. adults are either overweight or obese. The distinction between overweight and obese is made on the ba
PilotLPTM [1.2K]

Answer:

The probability that a randomly selected adult is either overweight or obese is 0,688

Step-by-step explanation:

Probability that an american adult is overweight = 0,331

Probability that an american adult is obese = 0,357

Let's find the probability that an adult is either overweight or obese, that means both events are mutually exclusive. We are interested in the probability that just one event occurs, that probability is the sum of their individual probabilities

P(overweight ∪ obese) = P(overweight) + P(obese) = 0,331 + 0,357 = 0,688
