Answer:
(a) -7, (b) 2
Step-by-step explanation:
a) When x = 0,
=> x² - 8x - 7
=> (0)² - 8(0) - 7
=> 0 - 0 - 7
=> - 7
b) When x = -1,
=> x² - 8x - 7
=> (-1)² - 8(-1) - 7
=> 1 + 8 - 7
=> 9 - 7
=> 2

Domain: x values
Range: y values
The relation would need to have (2, y) and (4, y). And also (x, 2) and (x, 8)
See which ones match

Answer:
<u>Sum of n terms of a GP:</u>
#1
- a₁ = 5
- r = 2
- n = 9
- S₉ = 5(2⁹ - 1)/(2 - 1) = 5(511) = 2555
Correct choice is C
-----------------------------
#2
- a₁ = 12
- r = 1/2
- n = 5
- S₅ = 12(1 - (1/2)⁵)/(1 - 1/2) = 12(31/32)/(1/2) = 23.25
Correct choice is A
Answer:
9 units or D
Step-by-step explanation:
The two numbers are 9 units apart as when you have -3, it takes positive 3 to get to 0. From 0 to 6 it is obviously 6. When you add 6 and 3 you get 9.
