well first you could see how many words he types per min. (228/4 = 57)
so if x is the # of mins, y = 57x
good luck!
32 empty square pieces are empty because the total number of squares in the board is 8X8 which is 64 and for the spaces filled theres 16 for each player and there are two players so its 16x2 which us 32. The total number of soaces minus the filled spaces will give you the number of empty spaces. So 64-32=32
Answer:
(x-4)^2+(y-4)^2=25
Step-by-step explanation:
the standard equation of a circle is (x-h)^2+(y-k)^2=r^2 where (h,k) are the coordinates of the center and r is the radius. In your case, just plug your the numbers into the equation
Slope intercept form would be y=9/16x-9/16
Domain:
-4 ≤ x ≤ 3
or in different form:
x ∈ [-4; 3]
