Answer 1

Answer: a₁ = -8 This is the first term in an arithmetic sequence.
d = 3, the common difference

a(n) = a₁ + d(n-1)

a₇ = -8 + 3(7-1)
a₇ = -8 + 3(6)
a₇ = -8 + 18
a₇ = 10

To check:
a₁ = -8
a₂ = -8 + 3 = -5
a₃ = -5 + 3 = -2
a₄ = -2 + 3 = 1
a₅ = 1 + 3 = 4
a₆ = 4 + 3 = 7
a₇ = 7 + 3 = 10

(-5a^3 - 2a^2) + (6a^3+9a^2+8a)

Answers

If you would like to calculate (-5a^3 - 2a^2) + (6a^3 + 9a^2 + 8a), you can do this using the following steps:

(-5a^3 - 2a^2) + (6a^3 + 9a^2 + 8a) = -5a^3 - 2a^2 + 6a^3 + 9a^2 + 8a = a^3 + 7a^2 + 8a

The correct result would be a^3 + 7a^2 + 8a.

PLEASE DON'T GUESS I NEED TO GET THIS RIGHT!!!!!!!!!Bob and his best friend Bill have the same birthday, but Bob is 3 years older than Bill. Let the variable x represent Bob’s age and y represent Bill’s age. Which equation models the relationship between Bill’s age and Bob’s age?
A. y = x/3
B. y = x + 3
C. x = y + 3
D. y = 3x

Answers

Well if Bob (represented by x) is three years older than Bill (y), the only one correct is x=y+3. Dividing by three wouldn't make sense (choice A), adding three more years onto Bob won't work (choice B), and multiplying Bob's age by three wouldn't work either (choice D). The answer is choice C.
x=y+3

Identify the fraction as proper, improper, or mixed. 16/12

Answers

in form a/b
Proper fraction is when a<b or it is less than 1 (when top number less than bottom number)

Improper is when a>b or when it is more than 1 (when top number greater than bottom number)

Mixed is a whole number with a fraction example 1 and 2/3, it can be the result of converting an improper fraction into a whole number and a proper fraction

16/12
top is more than bottom

Improper fraction

Suppose JK bisects angle LJM. The measure of angle LJK = (-10x + 3) and the measure of KJM = (-x + 21)º. Find the measure of angle LJM.

Answers

LJK = KJM -10x +3 = -x + 21 -10x + x = 21 - 3 -9x = 18 x = -2 KJM = -x + 21 = 2 + 21 = 23 LJM = LJK + KJM LJM = 23 + 23 LJM = 46º..
