Your answer is A.
2x - 6 = 2x + 8
Just looking at this, it doesn’t make sense. Two times a number - 6 cannot equal two times the same number +8.

But solving it mathematically, we want to get the variables on one side of the equation, so we subtract 2x from both sides:
2x - 2x -6 = 8
Then add 6 to both sides:
2x - 2x = 14
0 = 14 is untrue.

The other options’ answers:

B: x = 4.5
4x - 8 = 10
4x = 18
x = 4.5

C: has an infinite number of solutions. Anything you plug into x on one side of the equation you will plug in on the other side. Both sides are identical.

D: x = 1

Please lmk if you have any questions.

Find equation of vertical line through (-5, -3)

Novay_Z [31]

Answer:

x = -5

Step-by-step explanation:

Given that it is a vertical line, we know that it will only go through one x-value.

We are also given a point, (-5, -3).

This point tells us that the vertical line only goes through the x-value -5, so the equation will be x = -5.

Answer:

y-intercept: (0, 3)
axis of symmetry: x = -1

Step-by-step explanation:

The y-intercept is the constant, 3. It is the value of f(0).

The axis of symmetry of the quadratic function ...

f(x) = ax^2 +bx +c

is ...

x = -b/(2a)

Here, using that formula gives ...

x = -(2a)/(2(a)) = -1

The axis of symmetry is x = -1.

Last year you sold short 400 shares of stock selling at $90.00 per share. Six months later the stock had fallen to $45.00 per

a_sh-v [17]

Answer:

The selling of the stocks gave a profit of $16,675.

Step-by-step explanation:

The initial capital was 400 shares, that were valuated at $90.00. This is $36,000.

Six months after, the price drop to $45.00 per share. The stocks that you sold would be valuated a total of $18,000.

That is a relative profit of $18,000.

Then, we have to substract the dividends that you didn't get and the cost of transaction.

The dividends are two payments of $1.50 per share each. The total amount is 400*1.50*2=$ 1,200.

The cost of transaction is $125.

Then, the net profit from selling is:

P = $18,000 - $1,200 -$125= $16,675
