Express the terms of the following sequence by giving an explicit formula.
9, 12 15, 18, 21
A. u(n) = n + 3, where n = 1, 2, 3, 4, . . .
B. u(n) = 6 + 3n, where n = 1, 2, 3, 4, . . .
C. u(n) = 3 + n, where n = 1, 2, 3, 4 . . .
D. u(n) = 3n, where n = 1, 2, 3, 4, . . .
Answer:
B.
Step-by-step explanation:
The common difference is + 3 so we have an arithmetic sequence.
u(n) = a1 + d(n - 1)
= 9 + 3(n - 1)
= 9 + 3n - 3
= 6 + 3n.

find value of x also the answer choices are
a. 62.5
b. 9.65
c. 71.35
d. 103.25
Answer:
D.103.25
Step-by-step explanation:
To find the value of x, you need to know that the height of the donkey and the cactus are proportional and that the shadow of the donkey and cactus are also proportional to each other. Thus, you need to create a proportional and cross multiply to find the value of x.
x/59 = 7/4
After you cross multiply, the equation should look like this:
4x=413
Finally, you divide both sides or numbers by 4 to get 103.25 as your answer! Hope this helps!

Answer:
x=-8
(-8,-7)
Step-by-step explanation:
–9x + 9y = 9
–9x + 9(-7) = 9 (y=-7)
-9x-63=9
Both side +63
-9x=63+9
-9x=72
Both side divide -9
x=-8
y=-7

NEED HELP WITH GEOMETRY
Answer:
Please look down below
Step-by-step explanation:
∠1 + 69 + 47 = 180 (because straight line)
∠1 = 180 - 116
∠1 = 64
∠2 + ∠1 + 63 = 180 (because triangle)
∠2 + 64 + 63 = 180
∠2 = 180 - 127
∠2 = 53
∠3 + ∠1 = 180 (because straight line)
∠3 + 64 = 180
∠3 = 116
∠5 = ∠4 (given)
∠5 + ∠4 + ∠3 = 180
Denote ∠5 and ∠4 as x, so 2x
2x + ∠3 = 180
2x + 116 = 180
2x = 64
x = 32
∠5 = 32, ∠4 = 32
∠6 + 136 = 180 (because straight line)
∠6 = 44
∠7 + ∠6 + 47 = 180 (because triangle)
∠7 + 44 + 47 = 180
∠7 = 180 - 91
∠7 = 89
Elliot has 4 1/3 candy bars. He gives 2/3 of a candy bar to Sara and 1/3 of a candy bar to Bill. How much does Elliot have left? (Work it out)
Answer:
10/3 or 3 1/3
Step-by-step explanation:
4 1/3= 13/3 as a mixed fraction
he gives 2/3 to sara:
13/3 - 2/2= 11/3
then he gives 1/3 to bill:
11/3-1/3= 10/3
he has 10/3 which is equal to 3 1/3

Write your answer as a fraction in simplest form.
M
Answer:
61%
Step-by-step explanation:
7g+3b= 7th grade
4g+4b= 8th grade
70% chance of a girl getting picked from 7th grade
50% chance of a girl getting picked from 8th grade class
11g+7b= both classes
about 61% chance for both classes to be a girl picked?
What is 49% in a decimal
Answer:
0.49
Step-by-step explanation:
Answer:
Step-by-step explanation:
49% = 0.49 in decimal form. Percent means 'per 100'. So, 49% means 49 per 100 or simply 49/100. If you divide 49 by 100, you'll get 0.49 (a decimal number).
The fifth term of an arithmetic sequence is 23 and the 12th term is 72? Determine the first three terms of the sequence and the nth term
Answer:
the first term is a1
the distance between the numbers is d
we have:
a5 = a1 + 4d = 23
a12 = a1 + 11d = 72
so we have the equation:
a1 + 4d = 23
a1 + 11d = 72
=> a1 = -5
d = 7
=> an = -5 + 7(n - 1) = 7n - 12
with an = 7n - 12
=> a2 = 2
a3 = 9
so the first three terms is -5; 2; 9
