Answer:
44x +56y = 95
Step-by-step explanation:
To write the equation of the perpendicular bisector, we need to know the midpoint and we need to know the differences of the coordinates.
The midpoint is the average of the coordinate values:
((-2.5, -2) +(3, 5))/2 = (0.5, 3)/2 = (0.25, 1.5) = (h, k)
The differences of the coordinates are ...
(3, 5) -(-2.5, -2) = (3 -(-2.5), 5 -(-2)) = (5.5, 7) = (Δx, Δy)
Then the perpendicular bisector equation can be written ...
Δx(x -h) +Δy(y -k) = 0
5.5(x -0.25) +7(y -1.5) = 0
5.5x -1.375 +7y -10.5 = 0
Multiplying by 8 and subtracting the constant, we get ...
44x +56y = 95 . . . . equation of the perpendicular bisector
.78 cents for one quart <--- Answer
First you need to find how much is it per gallon
$37.20/12= $3.10
Now we need to find out how many quarts are in a gallon. Which is 4 quarts per 1 gallon
Now that we know this you need to divide the chost of one gallon by 4(# of quarts in one gallon)
$3.10/4= .78 cents
49,000 is the nearest round to the hundredth to 48,950
Answer:
35 + .2m
Step-by-step explanation:
The monthly fee of $35 is a base pay, and you don't change anything with it.
The "m" stands for minute, and since it costs $.20 for each minute, multiply the two together to get that part of the equation.
