Answer:
Step-by-step explanation:
You can just input the value of -3 into the equation to find value of k.
0=2(-3)^3 + 3(-3)^2 +3k -27
27= -54 +27 + 3k
27= -27 = 3k
27+27 = 3k
54/3 = k
18 =k

To answer this question, you'll need to use permutations and factorials.
Factorials are any integer with an ! after it. This means that all of the integers before that number are multiplied together with said number.
This question will use the following formula:
n represents the amount of items in a set, and r represents the amount of items in each combination within the set.
You have 18 students, and you can choose any combination of 3 students. Plug your values into the formula:
There are 4896 different combinations of students that Ms. Lunette can choose.
To obtain these 2 points within slope intercept form, what you would need to do, is first find the slope, using the formula for slope.
M = y2-y1/x2-x1 = 3 - 2/1 - 5 = 1/-4 or -1/4.
Knowing this, choose any one of the point and put it in the form y = mx + b.
Y = mx + b
2 = -1/4(5) + b
2 = -5/4 + b
2 = b - 5/4
b = 5/4 + 2/1
b = 5/4 + 8/4 = 13/4
Y = -1/4x + 13/4.
