Answer:

3

Step-by-step explanation:

To identify the y-intercept represented by the given equation, we need to get the equation into slope-intercept from:

y=mx+b

m=slope

b=y-intercept

Start with:

3x+2y=6

Subtract 3x from both sides of the equation:

2y=-3x+6

Divide both sides of the equation by the coefficient of y, which is 2:

y=-1.5x+3

Identify the y-intercept:

b=3

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle f(x) = 2(4)^x\\f(-2) \ is \ x = -2<u />

<u />

<u>Step 2: Evaluate</u>

  1. Substitute in <em>x</em>:                    \displaystyle f(-2) = 2(4)^{-2}
  2. Exponents:                          \displaystyle f(-2) = 2(\frac{1}{16})
  3. Multiply:                               \displaystyle f(-2) = \frac{1}{8}

Calculate the average rate of change for the graphed sequence from n = 2 to n = 6.
ddd [48]

Answer:

  -3

Step-by-step explanation:

The average rate of change from point (x1, y1) to point (x2, y2) is given by ...

  m = (y2 -y1)/(x2 -x1)

For the given points, this is ...

  m = (2 -14)/(6 -2) = -12/4 = -3

The average rate of change on the interval is -3.
