Answer:

49/4

Step-by-step explanation:

x^2 + 7x = 4

Take the coefficient of x

7

Divide by 2

7/2

Square it

(7/2) ^2 = 49/4

Add this to each side

x^2 + 7x  +49/4= 4+49/4

Are the following angle relationships possible? Explain.
mel-nik [20]

Answer:

no

Step-by-step explanation:

The 5x+30 is the supplementary angle of the interior one:

180 - 5x - 30 = -5x + 150

Then they have to add up to 180:

4x-9 + 2x+3 -5x + 150 = 180

which simplifies to x = 36

So the angles would be 135, 75 and -30, which is impossible!

The value of the collection originally was $1,000,000

What was the original value of the collection?

The original value of the collection is not known, hence, it is represented by X

The increase in value by $50,000 means that the value is X+$50,000

Now, when the error was discovered, it is now worth half of the  value previously

The new value is (X+$50,000)*0.5

New value=(X+$50,000)*0.5

The new value at this point is $525,000

$525,000=(X+$50,000)*0.5

$525,000/0.5=X+$50,000

$1,050,000=X+$50,000

X=$1,050,000-$50,000
