Answer:

( x +4)^2 + ( y-7)^2 = 36

Step-by-step explanation:

We can write the equation of a circle as

( x-h)^2 + ( y-k)^2 = r^2

where ( h,k) is the center and r is the radius

( x- -4)^2 + ( y-7)^2 = 6^2

( x +4)^2 + ( y-7)^2 = 36

And one US city the taxi cost is five dollars plus $.60 per mile if you are traveling from the airport there is an additional ch

GenaCL600 [577]

Let the number of miles be x.

Then, x miles cost 0.6x.

The initial fixed fee is $5, and the toll is $5.

cost = initial fixed fee + cost per mile + toll

46 = 5 + 0.6x + 5

0.6x + 10 = 46

0.6x = 36

x = 36/0.6

x = 60

You can travel 60 miles.

The length of a rectangle is 5 in longer than its width.

NeTakaya

Answer:

Length = 21

Width = 16

Step-by-step explanation:

We know that the formula for perimeter is:

P=2W+2L

And we also know that:

L=W+5

So then we put all that we know in the formula:

74=2W+2(W+5)

Now we expand the brackets and do some algebra:

74=4W+10 (-10)

64=4W (÷4)

16=W

Now that we know the width we can pop that into the length equation:

L=16+5

L=21
