HELP ASAP solve the equation using the properties of equality.<br><br><br>89= -5d+9

sergey [27]

Answer:

d = -16

Step-by-step explanation:

Step 1: Write equation

89 = -5d + 9

Step 2: Solve for <em>d</em>

<u>Subtract 9 on both sides:</u> 80 = -5d

<u>Divide both sides by -5:</u> -16 = d

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

89 = -5(-16) + 9

89 = 80 + 9

89 = 89

This is just like an exponential growth equation...

Final=initial*rate^periods

25000=12500(1.0525)^t

2=1.0525^t

ln2=t ln1.0525

t=ln2/ln1.0525

t=13.55

t=14 yrs
