coordinates of endpoint A are (-7,12)
Step-by-step explanation:
We are given midpoint B (x,y) =(-3,5)
One endpoint C (x₂,y₂)= (1,-2)
We need to find other endpoint A (x₁,y₁).
The formula to find midpoint is:
We can find the coordinates of endpoint A using these formula.
We have x=-3, x₁=? and x₂= 1
Putting values and finding x₁
Now, y=5, y₁=? and y₂= -2
SO, coordinates of endpoint A are (-7,12)

Answer:
$52.44
Step-by-step explanation:
Long method:
1. Convert the percentage into a decimal (15/100 = 0.15)
2. Multiply the decimal by the cost of the haircut (0.15 x $45.60 = $6.84)
3. Add this product by the cost of the haircut ($6.84 + $45.60 = $52.44)
Quicker Way (easier w/ a calculator)
1. Add 100% to the percentage she wants to add (100% + 15% = 115%) You can also express this as a number (115/100 = 1.15)
2. Multiply this new percentage by the cost of the haircut (1.15 x $45.60 = 52.44)
In a single equation, it would be
Answer:
1) f(x)<x+4
f(x)>-x-3
f(x)<5
2)2.5>0+2
2.5<0+3
2.5<0+5
