Answer:
b, c, e
Step-by-step explanation:
First, just simplify the inequality.
-18 < 5x - 8 < 17
-10 < 5x < 25
-2 < x < 5
Answers that fit this inequality:
-1, 0, 3
Answer:
270
Step-by-step explanation:
For any arithmetic sequence
nth term is given by
nth term = a + (n-1)d
where a is first term,
d is common difference
d is given by nth term - (n-1)th term
sum of n terms given by
sum = n/2(2a + (n-1)d)
________________________________________________
Given arithmetic sequence
-2,0,2,4,6,8...
first term a = -2
lets take third term as nth term and second term as (n-1)th term to find common difference d.
d = 2 - 0 = 2
using a = -2 , d = 2, n = 18
thus, sum of first 18 terms = n/2(2a + (n-1)d)
=18/2( 2*(-2) + (18-1) 2)
=9 ( -4 + 34)
=9 ( 30) = 270
Thus, sum of first 18 terms is 270.
Answer:
false is the answer ........
Answer:
y = 3/5x + 3
Step-by-step explanation:
→ Write down in y = mx + c
y = 3/5x + c
→ Substitute in coordinates
0 = -3 + c
→ Find c
c = 3
→ Rewrite
y = 3/5x + 3
