The Average Rate of Change<span> function describes the average rate at which one quanity is changing with respect to something else changing.
</span><span> For this case, the first thing you should do is observe the intervals for which the function decreases.
 Remember that the definition of average rate of change is given by:
</span> AVR = (f (x2) - f (x1)) / (x2-x1)&#10;
<span> For AVR to be negative, it must necessarily pass:
</span> x2\ \textgreater \  x1&#10;&#10;f (x1) \ \textgreater \  f (x2)<span>
 The interval that meets both conditions is:
 x = 0 to x = 2.5
 Answer:
 x = 0 to x = 2.5
 option 3</span>

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

7(2x - 5) = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 7:                   2x - 5 = 3
  2. Isolate <em>x</em> term:                2x = 8
  3. Isolate <em>x</em>:                         x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                  7(2(4) - 5) = 21
  2. Multiply:                             7(8 - 5) = 21
  3. Subtract:                            7(3) = 21
  4. Multiply:                             21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 4 is the solution to the equation.

For this case what you should see is the behavior of each function to find the correct answer.
 We have functions of the type:
 f (t) = a * (b) ^ t
 Thus,
 For I, we have:
 f (t) = 30 * (1.05) ^ t
 For V we have:
 f (t) = 30 * (0.95) ^ t
 For VI we have:
 f (t) = 30 * (0.85) ^ t
 Answer:
 option c.

Use the following compound interest formula to complete the problem currently you have two credit cards H and die card H has a b
abruzzese [7]

Answer:

  card I by $82.50

Step-by-step explanation:

As you know the compound interest formula is ...

  A = P(1 +r/n)^(nt)

For card H, P=1186.44, r=0.1474, n=1, t=3, so the balance will be ...

  A = $1186.44(1.1474^3) ≈ $1792.22

For card I, P=1522.16, r=0.125, n=12, t=3, so the balance will be ...

  A = $1522.16(1 +.125/12)^(12·3) ≈ $2210.44

__

The increase in card H is ...

  $1792.22 -1185.44 = $605.78

The increase in card I is ...

  $2210.44 -1522.16 = $688.28 . . . . . . card I increased more

The difference in the increases is ...

  $688.28 -605.78 = $82.50

Card I increased by $82.50 more than card H in the time period.
