Answer:

5/9

Step-by-step explanation:

y = 15 • 3^x

Let x = -3

y = 15 • 3^(-3)

The negative means the exponent goes to the denominator

y = 15 * 1/3^3

  = 15 * 1/27

  =15/27

Divide the top and bottom by 3

 =5/9

Translate this verbal description into a symbolic statement, acting from left to right:

(3/4)w + 5 = (1/2)(w) + 9

If we want to determine the value of w that satisfies this equation, begin by multiplying all four terms by the LCD (which is 4):

3w + 20 = 2w + 9

Then w = -11
