What is the sequence of second differences for ax +b?

Mathematics

MAVERICK [17]3 years ago
4 0

Answer:

ZERO

Step-by-step explanation  

Write the given function as

F(x) = ax + b

i.e Y = ax + b

now differentiate Y with respect to X

dY/dX = d (ax + b)/ dx

dY/dX = a

now again differentiate this function with respect to x

so,  d^2Y/dX^2 = d^2 (a)/dX^2

                         = 0 (ZERO)

note: differentiation of constant function is zero

Oksi-84 [34.3K]

Answer: the cost of one package of macadamia nut chip cookie dough is $1.5

the cost of one package of triple chocolate cookie dough is $2.5

Step-by-step explanation:

Let x represent the cost of one package of macadamia nut chip cookie dough.

Let y represent the cost of one package of triple chocolate cookie dough.

Mrs. Julien’s class sold 25 packages of macadamia nut chip cookie dough and 30 packages of triple chocolate cookie dough for a total of $112.50. This means that

25x + 30y = 112.5 - - - - - - - - - - - - -1

Mrs. Castillejo’s class sold 8 packages of macadamia nut chip cookie dough and 45 packages of triple chocolate cookie dough for a total of $124.50. This means that

8x + 45y = 124.5 - - - - - - - - - - -2

Multiplying equation 1 by 8 and equation 2 by 25, it becomes

200x + 240y = 900

200x + 1125 = 3112.5

Subtracting, it becomes

- 885y = - 2212.5

y = - 2212.5/- 885

y = 2.5

Substituting y = 2.5 into equation 1, it becomes

25x + 30 × 2.5 = 112.5

25x + 75 = 112.5

25x = 112.5 - 75 = 37.5

x = 37.5/25 = 1.5

The method used is the elimination method. It is more convenient to use.

Ab+bc=<br> this is adding of like terms
stellarik [79]

Answer:

(a+c)b OR it's already on simplified form

Step-by-step explanation:

depending upon what your instructor wants, they may want you to say it's already simplified (which happens sometimes).

HOWEVER, if you know how to factorize (which is essentially un-distributing), you could factor out the b which is common in both.

ab + bc \\  = b( \frac{ab}{b}  +  \frac{bc}{b} ) \\  = b(a + c)
