Answer:
Explicit formula: a(n)=3n-6
Recursive formula: a(n)=-3+(n-1)3 <--
Step-by-step explanation:
a(n)=3n-6 where a(1)=3(1)-6=-3 and d=3
Plug values into recursive formula:
a(n)=a1+(n-1)d
a(n)=-3+(n-1)3

i do t really know how to do this pls help
Answer:
for number 5 Subtract 18 from both sides of the equation
4+18−18=30−18
for number 1 Subtract 7 from both sides of the equation
so number 3 subtract 3 from each side and so on hope it helps
im not sure how to explain it but--
for example.. the first one
1) y + 7 = 12
first, you subtract 7 from both sides
so-- you'll subtract 7-7 on the left and 12-7 from the right
now, you have y by itself since 7-7 = 0
y = 12-7, or y = 5
also its important to note that when the equation is like 2) and uses subtraction (x-4) instead of addition (y +7)-- then you add to both sides
so for 2)-- you'd add 4 to both sides for 4 to cancel out to equal 0
your goal is always to isolate the variable on one side
please help !!!!!!!!!!

Answer:
n=7
Step-by-step explanation:
6(n-3) - 2n=10
Distribute
6n - 18 -2n = 10
Combine like terms
4n -18 = 10
Add 18 to each side
4n-18+18 = 10+18
4n = 28
Divide by 4
4n/4 = 28/4

Step-by-step explanation:
Solve the solution by substitution.
Y= —5x + 13
-6x + 6y = 6
Show/ explain your work
Answer:
the solution is (2, 3)
Step-by-step explanation:
Make this work easier by reducing the second equation:
-x + y = 1, or y = x + 1
Substititing x + 1 for y in the first equation, we get:
x + 1 = -5x + 13, or (after combining like terms):
6x = 12
Then x = 2, and bercause y = x + 1 (see above), y = 2 + 1 = 3
Then the solution is (2, 3)

The required percentage of the class to receive by A or a B is 40%. Option D is correct.
What is the percentage?A percentage is a number or ratio expressed as a fraction of 100. It represents a proportion or share of a whole that is divided into 100 equal parts. Percentages are often used to express changes, comparisons, or proportions in various fields such as finance, economics, and statistics.
Following the table,
The total tally is = 30
Total tally of A or B = 7 + 5 = 12
The percentage of A or B in the tally is given as,
= 12/30 * 100%
= 40%
