Answer:
5x-10
Step-by-step explanation:
0 duh because -6 is 6 before zero so if u add 6 u get 0
Answer:
-(x - 6)(x - 7).
Step-by-step explanation:
-x^2+ 13x - 42
= - (x^2 - 13x + 42
= -(x - 6)(x - 7)
Answer:
mean = 77
Step-by-step explanation:
We have a confidence interval of (59, 95) with a confidence of 99.7 percent
99.7 is 6 standard deviations from the mean, 3 on each side of the mean
mean - 3 sigma = 59
mean + 3 sigma = 95
We can use elimination to eliminate sigma. Add these equations together
mean - 3 sigma = 59
mean + 3 sigma = 95
---------------------------------
2 * mean = 154
Divide each side by 2
2 * mean/2 = 154/2
mean = 77
Maggie, you must either share the graphs or forget about them and solve the entire problem yourself with your own graph.
12 < 3b reduces to 4<b, and 2b + 14<4 reduces to 2b < -10, or b < -5.
You have only one variable here (b), so your graph will be one-dimensional (a horizontal line which is the b-axis).
First place a circle (open circle) at b = -5, and then draw an arrow to the left from b = -5. Next, place a circle at b = 4, and then draw an arrow to the right from b = 4. Note that there will be no arrow between b=-5 and b=4.
