Step-by-step explanation:
Addition property of equality because you add the two terms together to get what is below
Answer: there are 580 seats
Step-by-step explanation:
The number of seats in each row is increasing in arithmetic progression.
The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[(2a + (n - 1)d]
Where
a represents the first term of the sequence.
d represents the common difference.
n represents the number of terms in the sequence.
From the information given,
a = 10 seats
d = 2 seats (the seats in each row are increasing by 2)
n = 20(number of rows)
We want to determine the number of seats in 20 rows. Therefore
S20 = 20/2[(2×10 + (20 - 1)2]
S20 = 10(20 + 38) = 10×58
S = 580

Answer:
option c in both cases
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁ )
where m is the slope and (x₁, y₁ ) a point on the line
(1)
Here m = 2 and (x₁, y₁ ) = (- 3, - 5) , then
y - (- 5) = 2(x - (- 3) ) , that is
y + 5 = 2(x + 3)
(2)
Here m = 4 and (x₁, y₁ ) = (- 6, - 3) , then
y - (- 3) = 4(x - (- 6) ) , that is
y + 3 = 4(x + 6)
