5-11.
Positive 5 minus negative 11=
11-5=6
Now is 11 greater or 5, 11 is. And what is the integer of 11? A negative.
Therefore, the answer is -6.
Answer:
less than/equal to -2
Or, greater than/equal to 2.5
Step-by-step explanation:
2x² - x - 10 ≥ 0
2x² - 5x + 4x - 10 ≥ 0
x(2x - 5) + 2(2x - 5) ≥ 0
(x + 2)(2x - 5) ≥ 0
Roots: -2, 5/2
x《 -2 or x》5/2
Answer:
D) Yes. The five trials are independent, have only two outcomes, and have the same P(success); n = 5, r = 2, p = 1/6.
Step-by-step explanation:
The Number of boxes = 6
Box containing a prize = 1
Probability of success, p = box containing a price / number of boxes = 1 /6
Number of trials = 5
Probability of success on exactly 2 trials, r = 2
Hence,
P(r = 2) = nCr * p^r * (1-p)^(n-r)
n = 5 ; r = 2 ; p = 1/6
Using a binomial probability calculator :
P(r = 2) = 0.1608
Divide by 3 and you get m^2-81 so then factor and get 3(m+9)(m-9)
If you graph y=7x-9 and y=3x-1 the two lines will intersect at one point. That is how you graphically "solve" the system of equations.
Both of these lines are of the form y=mx+b where m is the slope and b is the y-intercept.
So for y=7x-9, the slope is 7 and the y-intercept is -9
For y=3x-1, the slope is 3 and the y-intercept is -1
....
The solution for this system occurs when both coordinates are equal to each other so we can say:
7x-9=3x-1 subtract 3x from both sides
4x-9=-1 add 9 to both sides
4x=8 divide both sides by 4
x=2, making y=3x-1 become:
y=3(2)-1=6-1=5, so the solution to the system of equations is:
(2,5)
