Answer:
Original Number = let we assume it is x
Number after decremented = y = 60
Total decrease = z = x-y = x-60
% of decrease = ((x-60)/x)*100 = 7.3
(x-60)*100 = 7.3x
100x -6000 = 7.3x
100x-7.3x = 6000
92.7x = 6000
x = 6000/92.7 = 64.73
Original Number = 64.73
Step-by-step explanation:
Answer:
f(-1) = -10
f(0) = -6
f(2) = 8
Step-by-step explanation:
As the function says, when x is below 0, the part that we have to use is 7x-3, and when is equal or greater we use 7x-6.
We do so and just replace de values of x in each equation.
Answer:
29
Step-by-step explanation:
add 23 to cancel the negative then add 6 to get the final answer
Answer:
V=-1
Step-by-step explanation:
Answer:
(x - 4)(x^2 + 7)
Step-by-step explanation:
x^2 is a factor of the first two terms: x^3 - 4x^2 = x^2(x - 4).
7 is a factor of the last two terms: 7(x - 4).
Note how (x - 4) is a factor of the entire four-term expression given above.
Then: x^3-4x^2+7x-28 = (x - 4)(x^2 + 7)
