Answer:

The correct option is : b. can be mild, moderate, or severe

Explanation:

Myocardial infarction, or heart attack, is a medical condition that occurs when the flow of blood stops or decreases to the human heart, thus causing damage to the heart muscles. Some of the symptoms include chest pain, nausea, sweating, cold sweat, fatigue, etc.

Heart attacks can be mild, moderate or severe and can also cause sudden death.

If the inadequate blood flow to the heart lasts long enough, it can lead to necrosis of the heart tissues.

Myocardial infarction can be diagnosed by electrocardiogram (ECG), echocardiogram, blood tests, X-ray, angiogram, MRI.

By substitution, justify that x= − 6 is a solution to x − 2 = − x − 14

Kamila [148]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

By substitution, justify that x = − 6 is a solution to x − 2 = − x − 14.

$\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}$

First, let's substitute the value of x as -6 in the equation.

$\tt \: x - 2 = - x - 14 \\ \dashrightarrow \: \tt \: ( - 6) - 2 = - ( - 6) - 14$

Now, let's solve it.

$\tt \: ( - 6 ) - 2 = - ( - 6 ) - 14$

Subtract 2 from -6 to get -8.

$\tt \: -8=-\left(-6\right)-14$

The opposite of -6 is 6.

$\tt \: -8=6-14$

Subtract 14 from 6 to get -8.

$\tt \: -8=-8$

Compare -8 and -8. We can see that both the LHS & RHS are equal to each other. So, hence we proved that x = − 6 is a solution of x − 2 = − x − 14.

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change.

ahrayia [7]

Answer:

Dear Mr. President,

Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.

- (Explain what you learned in class today ) I don't know what you were taught in class so you have to figure what to put here.

Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

Sincerely,
