<span>I am detailing it to show you how to calculate an explicite equation
Arithmetic Progression First term 7 , second 3 hence d=3-7 = - 4</span>
n=Term rank ==>║ 1 2 3 4 5 6 7......n
Value ====>║ 7 3 -1 -5 -9 -13 -17.......
a(n) (sub Notation║ a₁ a₂ a₃ a₄ a₅ a₆ a₇.....a(n)
Term 1 = a₁ = 7........................7-4(0)
Term 2 = a₂ = 3........................7-4(1)
Term 3 = a₃ = -1.......................7-4(2)
Term 4 = a₄ = -5.......................7-4(3)
Term 5 = a₅ = -9.......................7-4(4)
Term n = a(n) ============7-4(n-1)
So A. an = 7 − 4(n − 1); all integers where n ≥ 1
Answer:
x=49 exactly but a i forgot how to get range sry
Step-by-step explanation:
Answer:
A. 10
B. -8
C. 16
Step-by-step explanation:
A. -6x-2 = -6(-2)-2 = 10
B. -6x-2 = -6(1)-2 = -8
C. -6x-2 = -6(3)-2 = 16
Answer
(x-1) (x-4)
Step-by-step explanation:
I did this not long ago in class so that's the answer
2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
3/2(2/3x)=8/3(3/2)
6/6x=24/6
x=4
