Answer:
0.512 goals per game
Step-by-step explanation:
Given:
The number of games is represented by 'x' and number of goals is represented by 'y'.
Now, 'y' varies directly with x and at a constant rate.
A direct relationship line is given as:
Where, 'm' is the constant rate of change.
Now, for 
So, a point on the line is given as (82, 42).
Plug in the given values in the above equation and solve for 'm'. This gives,
Therefore, Keith scores at a constant rate of 0.512 goals per game.
Answer:
y
Step-by-step explanation:
Like radicals are radicals that have the same radical (the number into the square root) and the same radicand (the number above the root)
Here, only the last expression can be chosen.
I would subtract the 2nd from the first one
so -4x - -2x = -2x
4y - 4y = 0
-20 - -2 = -18
-2x = -18
now I would divide that by -2 to get the value for x
so no we have x = 9
now you just have to substitute that into one of the equations and simplify to get y
-2 X 9 + 4y = -2
-18 + 4y = -2
4y =16
y = 4
Answer:
Average ROC = 0
Step-by-step explanation:
Average ROC : (f(b) - f(a)) / (b - a) ... slope = (y'-y) / (x'-x)
a = -3 f(a) = 10 ... x=-3, y=10
b = 6 f(b) = 10 ... x'=6, y'=10
Average ROC = (10 - 10) / (6 - -3) = 0 / 9 = 0
Answer:
a) 15
Step-by-step explanation:
x+8
