Answer:
D.
Combination; number of ways = 10
Step-by-step explanation:
Permutation is when order matters
Combinations is when order doesn't matter.
Since there are two identical gift cards, it doesn't matter who gets the first gift card and who gets the second gift card, so this is a combination
There are 5 people choose 2
n!
--------
r!(n − r)!
where n is the number of items and r is how many we choose
5! 5*4*3*2*1
-------- = ------------------ = 10
2! (5-2)! 2*1 ( 3*2*1)
D.
Combination; number of ways = 10
The easiest way to graph these equations is to place them in slope intercept form.
2x = 10 - 3y
3y + 2x = 10
3y = -2x + 10
y = -2/3x + 3 and 3/10
Then just place values in for x to determine y
If x = 0, y = -2/3(0) + 3 and 3/10; y = 3 and 3/10
x = 1; y = -2/3(1) + 3 and 3/10; y = 2 and 19/30
Repeat as needed for more points, then plot the points on the graph, and draw a line through the points.
The same can be applied to the second equation.
3x + 2y = 5
2y = -3x + 5
y = -3/2x + 2 and 1/2
x = 0; y = -3/2(0) + 2 and 1/2; y = 2 and 1/2
x = 1; y = -3/2(1) + 2 and 1/2; y = 1
Repeat as needed for more points, then plot points and draw a line through them.

Answer:then the days would be on the x axis (dependant variable) and the Amount of candy would be on the y axis(independent variable=something that can be changed)
