(a) Find a simplified form of the difference quotient and (b) complete the following table.
f(x) = - 4x + 7​

Answers

Answer:

a) -4

b)

x    h                   [f(x+h) - f(x)] / h

3    2                  -4

3    1                   -4

3    0.1                -4

3    0.01              -4

Step-by-step explanation:

a) The difference quotient is:

[f(x+h) - f(x)] / h

Our function is -4x + 7​, then:

f(x+h) = -4(x+h) + 7​ = -4x -4h + 7

f(x) = -4x + 7​

f(x+h) - f(x) = -4x -4h + 7 - (-4x + 7​ )= -4x -4h + 7 +4x - 7​ = -4h

Finally:

[f(x+h) - f(x)] / h =  -4h/h = -4

b)

First point in the table:

x = 3

h = 2

f(x+h) = -4(3+2) + 7​ = -13

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -13 -(-5) = -8

[f(x+h) - f(x)] / h = -8 / 2 = -4

Second point in the table:

x = 3

h = 1

f(x+h) = -4(3+1) + 7​ = -9

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -9 -(-5) = -4

[f(x+h) - f(x)] / h = -4 / 1 = -4

Third point in the table:

x = 3

h = 0.1

f(x+h) = -4(3+0.1) + 7​ = -5.4

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -5.4 -(-5) = -0.4

[f(x+h) - f(x)] / h = -0.4 / 0.1 = -4

Fourth point in the table:

x = 3

h = 0.01

f(x+h) = -4(3+0.01) + 7​ = -5.04

f(x) = -4(3) + 7​ = -5

f(x+h) - f(x) = -5.04 -(-5) = -0.04

[f(x+h) - f(x)] / h = -0.04 / 0.01 = -4

Abigail has $30.00 to buy groceries.she needs to buy some apples,some bananas, and 3 pounds of potatoes.Fuji apples are $1.79 a pound ,bananas are$0.36 each, and potatoes are 2.99 for a 3 lb bag. If a represents the number of pounds of apples Abigail buys b represents the number of bananas she buys,which expression represents the amount of change she receives after her purchases?

Answers

Answer:

An expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01

Step-by-step explanation:

Let a represents the number of pounds of apples

Let b represents the number of bananas

Cost of 1 pound apple = $1.79

So, Cost of a pounds apples = 1.79 a

Cost of 1 banana = $0.36

Cost of b bananas = 0.36b

Cost of 3 lb bag of potato i.e. 3 pounds of potato = $2.99

So, Total cost = 1.79a+0.36b+2.99

Abigail has $30.00 to buy groceries

Let y be the change received by her

So, Change received by her:

y = 30-( 1.79a+0.36b+2.99)

y= 30-1.79a-0.36b-2.99

y=-1.79a-0.36b+27.01

Hence  expression represents the amount of change she receives after her purchases is y=-1.79a-0.36b+27.01

Part A: What is the value of 2x if 4x + 6 = 2x – 12?




Part B: What is the value of x – 3 if 24 = 6x – 18?

Answers

Answer:

Step-by-step explanation:

A) 4x + 6 = 2x - 12

Subtract 6 from both sides

4x + 6 - 6 = 2x - 12 -6

4x = 2x - 18

Subtract 2x form both sides

4x - 2x = 2x - 18 - 2x

2x = -18

B) 24 = 6x - 18

6x - 18 = 24

6x - 6*3 = 24

6(x - 3) = 24

Divide both sides by 6

He used everything he bought, and every student got a package. What is the largest number of students Dr. Stein can have in his class?

Answers

There are 30 students

The key word is "identical." If all students received identical packages, then Dr. Stein could have handed out 30 packages. He has a maximum of 30 notebooks to hand out, so if each package has one notebook, he can hand out 30 packages. Each of those 30 packages will also have 2 pencils and 10 erasers.

How did the great purge weaken the Soviet economy? MULTIPLE CHOICE:What is the discriminant of the quadratic equation 2x^2+8x5=0A. 104B. -24C. -104D. 24 Before answering the following question, re-read this section of the article: "Though the Greek city-states were unified to some extent in the face of an external threat, as that threat waned, conflicts between the city-states made a resurgence. Following the [Persian] wars, Athens emerged as the supreme naval power in Greece. It formed the Delian League, ostensibly to create a cohesive Greek network among city-states to ward off further Persian attacks. Under the leadership of Pericles, Athens grew so powerful that the Athenian Empire could effectively dictate the laws, customs, and trade of all her neighbors in Attica and the islands of the Aegean. The might of the Athenian Empire encouraged an arrogance in the policy makers of the day which grew intolerable to the other city-states. When Athens sent troops to help Sparta put down a Helot rebellion, the Spartans refused the gesture and sent the Athenian force back home in dishonor, thus provoking the war which had long been brewing. Later, when Athens sent their fleet to help defend its ally Corcyra (Corfu) against a Corinthian invasion during the Battle of Sybota in 433 BCE, their action was interpreted by Sparta as aggression instead of assistance, as Corinth was an ally of Sparta."Why might being a strong naval power have aided Athens in controlling many of its neighbors? 9. y=-2(x-3)10. 12x + 30 y = 1011. y = -5x+212. y=6+36-1)13. y-3 = 2x14. y=-3-4(x+9)intercept form Specialization encourages countries to be economically interdependent.Please select the best answer from the choices providedTF Please answer this correctly The volume of a stock is the number of shares traded for a given day.
