Answer:
23, 15, 7, 3
Step-by-step explanation:
Step 1. Isolate the variable x:
Step 2. Use the simplified inequality to graph:
- Select an OPEN point on x = -5
- Select a ray extending from -5 to positive infinity (GREATER than -5)
I hope this helps!
Width W = 10, length L = ?
50 = 2L + 2W
2L = 50 - 2*10 => L = 15
area = L*W = 15*10 = 150 sq.ft.
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.
