Answer:
missing terms are -2,3,8
Step-by-step explanation:
-7, ?, ?, ?, 13
To find missing terms we add last two term and divide it by 2
so that we will get middle term
so sequence becomes
-7, ?, 3, ?, 13
Again we add -7 and 3 and then divide it by 2 to get middle number
so sequence becomes
-7, -2, 3, ?, 13
Again we add 3 and 13 and then divide it by 2 to get middle number
-7, -2, 3, 8, 13
So, missing terms are -2,3,8
Answer:
(1,-4)
Step-by-step explanation:
x = -b/2a
a = 2
b = -4
x = 4/4
x = 1
Then substitute x = 1 into the equation to find y
y = 2(1)^2 - 4(1) - 2
y = -4
So, (1,-4)
For no real solution, you must have b^2 - 4ac of the quadratic formula be less than 0.
a = 1; b = 2; c = C
b^2 - 4ac < 0
2^2 - 4(1)(C) < 0
4 - 4C < 0
-4C < -4
C > 1
The only choice greater than 1 is 3.
Answer: the 4th choice, 3
