Mathematics

Answer:

15 1/3

Step-by-step explanation:

a = 7

b = -4

plugging the above value in |2a| - b/ 3

|2a| - b/ 3 = |2*7| - (-4)/ 3

|x| is modulus function so whatever be the value of be it negative or positive, modulus of this x is positive x

=> |14| + 4/ 3 = 14 + 4/3

=> (14*3 + 4)/3 = (42+4)/3 = 46/3 = 15 1/3

|2a| - b/ 3 = 15 1/3 when a = 7 and b = -4

Use Pythagorean theorem to find isos
myrzilka [38]

Answer:

x = 12 or \sqrt{144}

Step-by-step explanation:

Find the length of x for one side of the triangle first. To do this, use the Pythagorean Theorem which states: a² + b² = c² or in this case c² - a² = b². c² is 45 and a² is 3*3 or 9. Subtract 45-9 to get 36. Find the square root of 36 to get 6. The opposite side is also going to have a missing side length of 6 so add 6+6 to get 12 as x.

Hope it helps!

In your own words, explain why there is no solution to the following equation:| x-6|= -8 Also, knowing this, how does it help to
solniwko [45]

Answer:

Step-by-step explanation:

So the two lines before and after the expression means absolute value, or modulus of, knowing this, it means that the answer must always yield positive. So if x-6 is positive, it will stay positive, if x-6 is negative, it will turn positive, therefore it can never yield a negative value.

Now im assuming the second question is meant to be absolute value of x-5 is less than 0, because it makes no sense otherwise.

So now knowing that x-5 is always positive, or 0, but this inequality only wants less than 0, this means there are no solutions for the inequality.
