Answer:
(x + 1) (x^2 + 5)
Step-by-step explanation:
Simplify the following:
x^3 + x^2 + 5 x + 5
Factor terms by grouping. x^3 + x^2 + 5 x + 5 = (x^3 + x^2) + (5 x + 5) = x^2 (x + 1) + 5 (x + 1):
x^2 (x + 1) + 5 (x + 1)
Factor x + 1 from x^2 (x + 1) + 5 (x + 1):
Answer: (x + 1) (x^2 + 5)
hi
1st draw: green
2/12. (2 green out of 12 marbles), reduces to 1/6
2nd draw: blue
4/11 (4 blue marbles out of the 11 marbles remaining after 1st draw.)
Probability of theses BOTH happening: multiply these individual probabilities.
Conditional probability:
P(a and b) = P(a)P(b|a)
Prob(event 1) × Prob(event 2 given event 1).
1/6 • 4/11 = 4/66 = 2/33 or 0.0606. just a hair over 6% probability of the described sequence hapening.
Answer:
B. 3(y-5)/2. Once it's multiplied it equals 3y/2 - 15/2
Step-by-step explanation:
Answer:
x = 0.00559234073 for 1 second
x = 0.0111846815 for 2 seconds
Step-by-step explanation:
We first need to know that 1 mile = 1609.344 meters to get one unit to use or else it'll be confusing.
For 1 second, x will be replaced by 1.
So:
y=9(1)
y=9
And for 2 seconds, x will be replaced by 2.
So:
y=9(2)
y=18
These are the measurements in meters. Then, we need to find what it is in miles.
So we can use a proportion for this.
1/1609.344 = x/9
1609.344x = 9
x = 0.00559234073 for 1 second
For 2 seconds:
1/1609.344 = x/18
1609.344x = 18
x = 0.0111846815 for 2 seconds
Answer:
x =
y =
Step-by-step explanation:
2x = 10y - 8
3x + 4y + 5 = 0
2x = 10y - 8
x = 5y - 4
3x + 4y + 5 = 0
3 ( 5y - 4 ) + 4y + 5 = 0
19y - 7 = 0
19y = 7
y =
x = 5y - 4
x = 5 ( ) - 4
x =
