Answer:
2nd one is parallel and last one is perpendicular.
Answer:
The function
f(x) = x3 + 2x2 − x − 2
is a trinomial and it is expected that it has three factors corresponding to the three roots. The possible roots could 1, -1, 2, or -2. Trying out 1
f(1) = 1 + 2 - 1 - 2 = 0
According to the remainder theorem (x - 1) is a factor. By doing synthetic division
1 | 1 2 -1 -2
1 3 2
1 3 2 0
f(x) = (x - 1)(x2 + 3x + 2)
which can further be factored into
f(x) = (x -1)(x +1)(x + 2)
The three factors are
x-1
x+1
x+2
which are all linear expressions
Step-by-step explanation:
Answer:
y=3x—1
Step-by-step explanation:
The line contains point (2,5)
so if we put x=2 in the equation, that'll give us y=5
only option that contains point (2,5) is:
Answer:
answer is 362,880
Step-by-step explanation:
9!= 9×8×7×6×5×4×3×2×1=362,880
Answer:
11 hours
Step-by-step explanation:
The number of machines working in the factory = 6 machines
Decreasing it by a factor of 2 =
6 ÷ 2 = 3 machines.
Hence:
If 6 machines complete a big order = 22 hours
3 machines = x hours
Cross Multiply
6 machines × x hours = 22 hours × 3 machines
x hours = 22 hours × 3/6
= 66/6
x = 11 hours
Therefoee, it would take 11 hours to fill the order if the number of working machines decreased by factor of 2.
