Answer:
To label 6.5 on a number line, put the plot between the 6 and 7.
Same thing goes for 8.5, except the plot would go between the 8 and 9.
8.5 > 6.5
Step-by-step explanation:
1.) Since 8.5 and 6.5 are decimals, they are not a whole number which is why they go right in the middle of the two numbers they are behind and in front of.
2.) > means greater than, and 6.5 is smaller than 8.5 therefore we use the greater than sign, pointed towards the 8.5.
I hope this helps! :)
If the 10 videotapes are distinct (different) and the order of selection is immaterial, then there are
C(10,3)=10!/(3!(10-3)!)=10!/(3!7!)=10*9*8/(1*2*3)=120
ways to select three videotapes out of 10.
Answer:
x=2,y=−1
Step-by-step explanation:
Solve for y in the first equation.
y=−9x/11+7/11
0=−2y+10−6x
Replace all occurrences of y with −9x/11+7/11 in each equation.
0=−48(x−2)11
y=−9x11+711
Solve for x in the first equation.
x=2
y=−9x/11+7/11
Replace all occurrences of x with 2 in each equation.
y=−1
x=2
The solution to the system is the complete set of ordered pairs that are valid solutions.
(2,−1)
The result can be shown in multiple forms.
