Answer:
(10,8)
Step-by-step explanation:
Symmetry over x axis: you keep x, but change the sign of y value.
So, the symmetric of (10,-8) is (10,8)
So, to find the number of seats already replaced:
5 x 236 = 1180
1 x 348 = 348
1190 + 348 = 1528
So 1528 seats have been replaced.
3000 - 1528 = 1472
And 1472 seats still need to be replaced.
Hello,
Let me try out the solution for you.
Consider the below scenarios for the equation y = |x+5|-|x-5|
Case 1:
when x more than or equal to 5
then y=(x+5)-(x-5) = 10
hence y=10
Case 2:
when -5<x<5
y=(x+5)-(-(x-5)) = 2x
y=2x so y can take 9 values corresponding to x={-4,-3,-2,-1,0,1,2,3,4}
Case 3:
when x less than or equal to -5
y= -(x+5)-(-(x-5))
y=-10
Hence if we combine all 3 cases we get that y can take total of 11 values.
Answer:
Step-by-step explanation:
For the first symbol, there are 9 options to choose from. Then 8, then 7, and so on. Since each player chooses 5 symbols, they will have a total of 
permutations possible. Since the order of which they choose them matters (as a different order would be a completely different password), it's unnecessary to divide by the number of ways you can rearrange 5 distinct symbols. Therefore, the desired answer is 15,120.
L= 4*B+42
L= the load
B is the weight of each brick
42 is the weight of the carrier
