1)  phone

38.95 = 0.03 * mins + 29.95

9.00 = 0.03 * mins

9.00 /0.03 = mins

300 = mins

so he used 300 minutes  :)

2) books

8.70 =14 * bookPrice + 2.40

A circle with the equation (x + 6)2 + (y + 3)2 = 16 is reflected over the line x = 2.
fomenos

Answer: (x-10)^{2}+(y+3)^{2}=16

Step-by-step explanation:

We know the center of the original circle is (-6, -3). After reflecting this over the line x=2, the new center is now (10, -3).

Thus, the equation of the circle is (x-10)^{2}+(y+3)^{2}=16.

What is the abscissa of the midpoint of the line segment whose endpoints are (5√2,2√3) and (√2,2√3)
xxMikexx [17]
Let
A------> <span>(5√2,2√3)
B------> </span><span>(√2,2√3)

we know that
</span>the abscissa<span> and the ordinate are respectively the first and second coordinate of a point in a coordinate system</span>
the abscissa is the coordinate x<span>

step 1
find the midpoint
ABx------> midpoint AB in the coordinate x
</span>ABy------> midpoint AB in the coordinate y
<span>
ABx=[5</span>√2+√2]/2------> 6√2/2-----> 3√2
ABy=[2√3+2√3]/2------> 4√3/2-----> 2√3

the midpoint AB is (3√2,2√3)

the answer is
the abscissa of the midpoint of the line segment  is 3√2

see the attached figure
