Answer:
5.25
Step-by-step explanation:
I got this problem on imagine math and I got it right (the second time)
Answer:
The sum of the first twenty-seven terms is 1,188
Step-by-step explanation:
we know that
The formula of the sum in arithmetic sequence is equal to
where
n is the number of terms
a1 is the first term
d is the common difference (constant)
step 1
Find the common difference d
we have
n=7
a1=-8
S=28
substitute and solve for d
step 2
Find the sum of the first twenty-seven terms
we have
n=27
a1=-8
d=4
substitute
•
(-9, 3) is a solution to the equation.
(2, - 4) is a solution to the equation.
Neither ordered pair is a solution.
Both ordered pairs are solutions.
Answer:
(2, - 4) is a solution to the equation
Step-by-step explanation:
Substitute the x and y coordinates of the points into the left side of the equation and if equal to the right side then they are a solution.
(- 9, 3 )
6(- 9) -
= - 54 - 1.5 = - 55.5 ≠ 14 ← not a solution
(2, - 4)
6(2) -
= 12 + 2 = 14 ← This is a solution
Thus (2, - 4) is a solution to the equation
B) 5
C) 0
D) -5
( i kept getting -4 am i wrong or are the choices wrong?)
Answer:
d: -5
Step-by-step explanation:
when you plug in all the answer choices -5 is the only true answer
