Answers

Answer:

4x^2 +2x +16

Step-by-step explanation:

7x2 + 4x + 10) - (3x2 + 2x - 6)

Distribute the minus sign

7x2 + 4x + 10) - 3x2 - 2x + 6

Combine like terms

7x2 + 4x + 10)

Answer:

(7×2 + 4x + 10) - ( 3×2 + 2x - 6)

(14 + 4x + 10) - ( 6 + 2x - 6)

(4x + 14 +10) - ( 2x + 6 - 6)

(4x + 24) - ( 2x )

4x + 24 - 2x

4x - 2x + 24

Sabrina is using an online calculator to calculate the outputs f(n) for different inputs n. The ordered pairs below show Sabrina's inputs and the corresponding outputs displayed by the calculator: (1,6), (2,11), (3,16), (4,21)

Which of the following functions best represents the rule that the calculator used to display the outputs?

A) f(n)= 5n-1

B) f(n)= 5n+1

C) f(n)= 4n+3

D) f(n)= 4n-3

Answers

Plug in the point (1,6) into each answer choice.

A) f(n) = 5n - 1
f(1) = 5(1) - 1 = 5 - 1 = 4
(1,4) ≠ (1,6)

Answer choice A is incorrect.

B) f(n) = 5n + 1
f(1) = 5(1) + 1 = 5 + 1 = 6
(1,6) = (1,6)

Answer choice B is correct.

C) f(n) = 4n + 3
f(1) = 4(1) + 3 = 4 + 3 = 7
(1,7) ≠ (1,6)

Answer choice C is incorrect.

D) f(n) = 4n - 3
f(1) = 4(1) - 3 = 4 - 3 = 1
(1,1) ≠ (1,6)

Answer choice D is incorrect.

Your answer is B) f(n) = 5n + 1
