Answer: white = $13, double = $14

<u>Step-by-step explanation:</u>

Let white chocolate chip dough = x

Let double chocolate chip dough = y

Mary:      3x + 2y = 67

Darryl:  <u> -(3x + 4y = 95)</u>

                     -2y = -28

                  <u> ÷-2   </u>  <u>÷-2  </u>

                        y = 14

3x + 2y = 67

3x + 2(14) = 67

3x + 28 = 67

<u>       -28 </u>  <u>-28</u>

3x         = 39  

<u>÷3        </u>   <u>÷3  </u>

 x         = 13

If ƒ(x ) = 3x + 1, then ƒ(a + h ) - ƒ(a ) =
Brrunno [24]

Answer:

If ƒ(x ) = 3x + 1, then ƒ(a + h ) - ƒ(a ) = 3h

Step-by-step explanation:

Given ƒ(x ) = 3x + 1, then to calculate  ƒ(a + h ) - ƒ(a ), you need to replace "x" for (a + h) and a, respectively.

So...

f(a +h) = 3(a + h) + 1

and

f(a) = 3a + 1

Then

  ƒ(a + h ) - ƒ(a ) = 3 (a + h) + 1 - [3a +1] = 3a + 3h + 1 - 3a - 1 = 3h.

So, ƒ(a + h ) - ƒ(a ) = 3h
