Answer:
A The sum of the first 11 terms is 88
Step-by-step explanation:
Since -4 - (-7) = -1 - (-4) = 2 - (-1) = 3
Your sequence is an arithmetic sequence with a common difference of 3.
The formula for the sum of an arithmetic sequence is
where 
In your case
, n = 11 and 
We know everything except the eleventh term.
So, we need to find the eleventh term or
=
+ (n - 1)d
= -7 + (11 - 1)3
= -7 + 30 = 23
Now, S = 
The sum of the first 11 terms is 88
Answer: the answer choice “d” is correct
Step-by-step explanation:
because the different symbols mean different things and yeah
Answer: 6.
We found the factors and prime factorization of 18 and 24. The biggest common factor number is the GCF number.
Answer:
y = x - 1
Step-by-step explanation:
Since the line is parallel to y = x + 5, it will have the same slope, which is 1.
Plug in the slope and the given point into y = mx + b, and solve for b:
y = mx + b
2 = 1(3) + b
2 = 3 + b
-1 = b
Then, plug in the slope and b into the equation:
y = mx + b
y = x - 1
So, the equation is y = x - 1
Yes.
the properties of an isosceles trapezoid are:
- the bases are parallel
- opposite sides are congruent
- the angles on either side of the bases are congruent
- the diagonals are congruent
