F(x)= (x-p)²+q where (p,q) is min point
f(x)=(x-1)²-2
min point is (1,-2)
the answer is first picture
3 x - 7 = 5 x + 13
3 x - 5x = 13 + 7
-2x = 20
x = 20 / -2
x = - 10
<em>The regular price was $110</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em />
<em>60% .......... $66</em>
<em>100% ..........$ x</em>
<em>x = 100×66/60</em>
<em>= 6600/60</em>
<em>= $ 110</em>

<em>Good luck !</em>
<h3>
Answer: b+5a</h3>
Explanation:
The commutative property of addition is where we can add two numbers in any order.
The general equation is x+y = y+x
A more concrete example would be something like 2+3 = 3+2 since both sides simplify to 5.
For 5a+b, it is the same as b+5a. We swap the two terms.
This is a 30-60-90 triangle
opposite side of rigt angle=2x
opposite side of 60 degrees is x√3
opposite sides of 30 degree is x
the right angle is at the base of the building so therefor
200=x
2x=distance from surveor to top of building and x√3=height of building
x=200
200√3≈346.41
the answer is 346.41 feet
