For this case we have the following variables:
x: number of games
y: number of remaining tokens
The expression that models the problem is given by:
y = -3x + 75
Answer:
the number of tokens that remain is:
y = -3x + 75
B] The rule represents the reflection over y-axis is given by:
(x,y)⇒(-x,y)
c]Using this rule, the image would be located onto the pre-image when reflected again. This implies that it will be mapped onto the original point.
d] When the new pentagon is rotated 90° clockwise, the new coordinates will be as follows:
the rule for this rotation is given by:
(x,y)⇒(-y,x)
thus using the above rule new coordinates will be:
A"(-1,8), B"(-3,9), C"(-2,6), D"(-5,3) and E"(-1,4). The new figure is shown in the graph.

Answer:
y = -x + 9
Step-by-step explanation:
Here, we want to write the equation of a line
mathematically, if two lines are perpendicular, the product of their slopes is -1
Comparing the given equation with the general form of;
y = mx + b
where m is the slope and b is the y-intercept, we can see that the slope value is 1
So the slope of the second line will be;
-1/1 = -1
now we want to write the equation of a line that has a slope of -1 and passes through the point (-4, 13)
we use the point-slope form here
That will be;
y-y1 = m(x-x1)
y-13 = -1(x+ 4)
y-13 = -x - 4
y = -x -4 + 13
y = -x + 9
