Answer:
before "however"
Step-by-step explanation:
However is a throw-in word and should be both preceded and superseded by a comma.
Answer:
B
Step-by-step explanation:
The differences in the terms of f(x) are + 3, + 5, + 7
Since the differences are not constant the relationship is not linear
Note the differences in the differences are + 2, + 2,
The second differences are constant indicating a quadratic relationship
Note the relationship between x and f(x)
x = 1 → 1² = 1 ← require to add 5, that is 1 + 5 = 6 ← value of f(x)
x = 2 → 2² = 4 ← require to add 5, that is 4 + 5 = 9 ← value of f(x)
x = 3 → 3² = 9 ← require to add 5, that is 9 + 5 = 14 ← value of f(x)
x = 4 → 4² = 16 ← require to add 5, that is 16 + 5 = 21 ← value of f(x)
Thus f(x) = x² + 5 → B
Always true .
Negative a is always<0
B<0 so b is negative. Negative times negative is positive > 0 so
-b > -a
Answer:
11. -42
12. 9
13. 100 + (-100) = 0
14. 6 + (-4) = 2
Step-by-step explanation:
11. -42 + 36 would be the same as 42 - 36 but in this case it's negative, so that would be -6.---- -6 + (-36) equals -36 minus 6, or -42 (a negative plus a negative is always a negative)
12. -17 + 17 = 0 , 0 + 9 = 9
13. since the hawk started at 100 ft, add (-100) to get 0 (ground level)
14. leah ran 6 blocks north, then 4 blocks south, so add 6 + (-4)
