Answer:
A(10, -9)
Step-by-step explanation:
The relation between coordinate of point A(Ax, Ay), point B(Bx, By), and midpoint T(Tx, Ty) of segment line AB is expressed by formula:
Ax + Bx = 2Tx
Ay + By = 2Ty
=>
Ax + (-2) = 2 x 4
Ay + 3 =2 x (-3)
=>
Ax - 2 = 8
Ay + 3 = -6
=>
Ax = 8 + 2
Ay = -6 - 3
=>
Ax = 10
Ay = -9
=> A(10, -9)

60 seconds in a minute, but if you divide 60/3, you’ll get 20. So 20*4=80 gallons/min. If you multiply 80*60=4,800 gallons/hr
Answer:
Step-by-step explanation:
The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.
The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.
Also, remember we are using 3.14 for pi.
- = 3.14
Substitute these values into the formula.
Multiply.
The circumference of the circle is <u>163.28 yards.</u>

Answer:
all real numbers except x = 0
Step-by-step explanation:
The given equation has undefined terms when x=0, so the domain must exclude that value.
The domain of the terms of the equation is "all real numbers except 0."

The solution can be found by adding 1/(2x) to both sides and comparing the terms.
9/4 = 8/(2x) +1/(2x)
9/4 = 9/(2x)
4 = 2x . . . . match denominators of the same numerator
2 = x . . . . . the solution to the equation
