Answer:
The answer is A :)
Step-by-step explanation:
(x+1)-5(x+1+3)
(x+1)-5(x+4)
x + 1 - 5x - 20
-4x - 19
Answer:
7n + 5 − 9n = 8 − 2n − 3 = true
-2 n + 5 = 5 - 2 n = true
Step-by-step explanation:
Left-hand side:
Simplify the following:
7 n - 9 n + 5
Grouping like terms, 7 n - 9 n + 5 = 5 + (7 n - 9 n):
5 + (7 n - 9 n)
7 n - 9 n = -2 n:
Answer: -2 n + 5
____________________________
Right-hand side:
Simplify the following:
-2 n - 3 + 8
Grouping like terms, -2 n - 3 + 8 = (8 - 3) - 2 n:
(8 - 3) - 2 n
8 - 3 = 5:
Answer: 5 - 2 n
Point slope form
y - -6 = (-1/2)(x - -4)
y + 6 = (-1/2)x - 2
y = (-1/2)x - 8
Answer: y = (-1/2)x - 8
Check. Clearly slope is -1/2, good. (-1/2)(-4)-8=2-8=-6 good
I said A the number of AP
