What is the equation for an arithmetic sequence with a first term of 5 and a second term of 2? (5 points) an = 5 − 2(n − 1) an = 5 + 2(n − 1) an = 5 − 3(n − 1) an = 5 + 3(n − 1)
Answers
Answer:
an = 5 − 3(n − 1)
Step-by-step explanation:
First term,a = 5
Second term = 2
Common difference,d = 2 - 5 = -3
nth term = a + d(n - 1)
= 5 -3(n - 1)
Check
When n = 2
2nd term = 5 - 3(2 - 1)
= 5 - 3(1)
=5 - 3
= 2
2nd term = 2
You will be redoing the moulding around the windows and the door of your bedroom. You have 2 windows that measure 110 cm x 65 cm, and the door measures 76 cm x 198 cm. You do not install moulding along the base of the door. Moulding costs $0.98 per foot. What will be the total cost of the moulding for this project?
Answers
Answer:
$31.26 if you could buy the exact amount necessary
Step-by-step explanation:
2[2(110)+2(65)]=windows
700 = windows
76+2(98)=door
272=door
total=972 cm=31.9 feet (you might have to buy 32 feet though)
31.9x0.98=$31.26
X-2y=10 x+3y=5 please hellppppppp
Answers
Answer:
x=8,y=-1
Step-by-step explanation:
x-2y=10
x=10+2y
10+2y+3y=5
5y=-5
y=-1
x-2(-1)=10
x=8
The solution to the system of equations x - 2y = 10 and x + 3y = 5 is x = 8 and y =-1
How to solve the equation?The system of equations is given as:
x - 2y = 10
x + 3y = 5
Subtract both equations
-2y - 3y = 10 - 5
Evaluate
-5y = 5
Divide both sides by -5
y = -1
Substitute y = -1 in x - 2y = 10
x - 2(-1) = 10
This gives
x + 2 = 10
Subtract 2 from both sides
x = 8
Hence, the solution to the equations is x = 8 and y =-1

7. Jena has a triangular garden with a perimeter that can be represented by 25r ^ 2 - 9r + 14 . The sum of two sides of the garden is represented by 10r ^ 2 + 12r + 9 . Which expression represents the length of the third side ?
Answers
Answer: [tex]15r^2-21r+5[/tex]
Step-by-step explanation:
Given: Perimeter of triangular garden = [tex]25r^2 - 9r + 14[/tex]
The sum of two sides of the garden = [tex]10r^2 + 12r + 9[/tex]
Perimeter is the sum of all sides of a triangle.
Third side = Perimeter of triangular garden - sum of two sides of the garden
[tex]=25r ^ 2 - 9r + 14-(10r ^ 2 + 12r + 9)\\\\=25r ^ 2 - 9r + 14-10r ^ 2 - 12r - 9\\\\=15r^2-21r+5[/tex]
The expression represent the third side = [tex]15r^2-21r+5[/tex].

Answer:
8. s(-2) = 3, s(0) = 2, s(4) = 0
Look at the table for each of the values of x in s(x) and see what the y-value is. For example, for s(-2) you look at what y is when x = -2. It would be y = 3.
9. when x = -4, so s(-4)
Look through the table to find the row where y = 4. x would be -4.
10. -1
You can see that each time x goes up by 2, y goes down by 1. This means that the next row would say x = 6 and y = -1. The predicted value of s(x) is -1.

Kevin from Pullman was offered a deal to write story problems for ST2 publishing Company. For every 5 he wrote he was paid $12.00. How much did Kevin get paid per problem?
Answers
Answer: $2.40
Step-by-step explanation:
If Kevin gets 12 dollars for every 5 problems, we will need to divide 12 by 5 to find the unit rate; how much Kevin gets for each problem.
12 ÷ 5 = 2.4, and in dollars it is equal to $2.40. Because of this, Kevin is paid $2.40 for each problem he makes for the ST2 publishing Company.
