Y - y1 = m(x - x1)
slope(m) = -56
(8,-4)...x1 = 8 and y1 = -4
now we sub...pay close attention to ur signs
y - (-4) = -56(x - 8)....not finished yet
y + 4 = -56(x - 8) <===

In a complete sentence, write down a method you could use to determine if an equation is written in the correct way.
Sergio039 [100]

An equation is written in a correct way if the equation is balanced. If you want to find out if the equation is balanced, you have to count how many molecules of each element is present and then just balance the equation on the left side and the right side.

Answer:

  Stock A

  • d(1 +0.05)
  • 1.05d
  • d +0.05d

  Stock B

  • d -0.05d
  • d(1 -0.05)
  • 0.95d

Step-by-step explanation:

When we say something is increased (or decreased) by a percentage, we mean that the percentage of the original amount is added to (or subtracted from) the original amount.

Of course, you know that 5% = 5/100 = 0.05, so that an increase of 5% in d would be ...

   d + 0.05d . . . . . 5% of the original amount (d), added to d

Factoring out d gives another version of this expression:

  d(1 +0.05)

and combining the numbers gives yet another version of the same expression:

  1.05d

These are the ways that the increase in Stock A can be expressed:

  d +0.05d

  d(1 +0.05)

  1.05d

__

Similarly, if the "increase" is negative, as for Stock B, we can use the same sorts of expressions. +0.05 gets replaced by -0.05, but the form of the expression is the same.

  d - 0.05d . . . . . the original amount decreased by 5%

  d(1 -0.05) . . .  . .d factored out

  0.95d . . . . . . . . the numerical coefficient simplified

A little while ago, a dolphin was swimming below sea level at -7 meters. Now the dolphin is jumping at 0.5 meters. What does thi
zimovet [89]

This means that the dolphin ascended 7.5 meters in total.

The sea level is 0.

We know that to start off with, the dolphin was seven meters under the sea level.

We also know that the dolphin jumped .5 meters above the sea level.

This is a matter of absolute value; we are looking to find total distance, not actual height (which we already know, .5). Therefore, we ignore the negative sign and instead regard how many places each measurement is away from zero, which is another way of saying absolute value.

Take a look at x.

| x |

The lines surronding x represent absolute value. With that in mind, I can show you the process:

| -7 | + | .5 | = 7.5

is the same as saying 7 + .5 = 7.5
