Olly drove 56 km from Liverpool to Manchester. He then drove 61 km from Manchester to Sheffield. Olly’s average speed from Liverpool to Manchester was 70 km/h. Olly took 75 minutes to drive from Manchester to Sheffield.
(a) Work out Olly’s average speed for his total drive from Liverpool to Sheffield.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet

answer: the answer is d

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

step-by-step explanation:

because it just is
