The first four terms of the sequence that follows the rule is 2, -1, 5 and -7
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. Let a represent the third term, hence if the 4th term is -7:
-7 = -2a + 3
a = 5
Let b represent the second term, hence:
5 = -2b + 3
b = -1
Let c represent the first term, hence:
-1 = -2c + 3
c = 2
The first four terms of the sequence that follows the rule is 2, -1, 5 and -7

Convert foot to inches:
1 foot = 12 inches
23 feet ⇒ 23 feet × 12 inches/ft = 276 inches
Divide:
276 ÷ 9 = 30 pieces with remainder
Remainder = 276 - (9×30) ⇒ 276 - 270 = 6
ANSWER: There will be 6 inches long remaining in length after cutting the string into 30 pieces equal lenght of 9 inches each.
Answer:
x=17/11
Step-by-step explanation:
1. 7−3(x−4)=2(4x+1)
2. −3x+19=8x+2
3. −3x+19−8x=8x+2−8x
4.−11x+19=2
5. −11x+19−19=2−19
6.x=(17/11)
Hope this helps :)

1a, 64/4=16 x=16cm
1b, 2(5x+2x)=98
2(7x) =98
14x=98
x=7
1c, 5(x+4)=45
5x+20=45
5x=25
x=5
Answer:
I'm not sure what you are looking for but I'm assuming you are finding r.
r is equal to 4.
Step-by-step explanation:
6 = r + 2
In order to find r, you have to subtract 2 from 6.
So, r = 6 - 2 = 4
