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.
4.30A+5.70B=855.40
A+B=168
A=168-B
substitute
4.30(168-B)+5.70B=855.40
4.30*168-4.30B+5.70B=855.40
1.40B =855-4.30*168
1.40B=132.60
B=132.60/1.40= 94.7 pounds≈95 pouds
Answer:
Linda earned 2 points on 14 turns.
Step-by-step explanation:
Given that Linda has played 16 turns and has obtained 34 points, taking into account that in each turn she can obtain 2 or 3 points, to determine the number of turns in which she obtained 2 points, the following table must be performed:
-If in 16 turns she obtained 2 points, the total points will be 32
-If in 15 turns she obtained 2 points and in 1 turn she obtained 3 points, the total points will be 33
-If in 14 turns she obtained 2 points and in 2 turns she obtained 3 points, the total of points will be 34
Therefore, Linda scored 2 points in 14 of the 16 turns played.
3(y-9)-y=7
3y - 27 -y = 7
2y = 34
Y = 17
3(x) -17 = 7
3x = 24
X = 8
