Answer:
6108795
Step-by-step explanation:
To obtain the number of ways the committee can be selected :
4 teachers from the 12 teachers available and 3 students from the 43 students available
Using combinatorics :
12C4 * 43C3
recall :
nCr = n! ÷ (n - r)!r!
Using calculator :
12C4 = 495
43C3 = 12341
12C4 * 43C3
495 * 12341
= 6108795
5 times (-17)= -85 so you should have said -85

▹ Answer
<em>(-2, 1)</em>
▹ Step-by-Step Explanation
4x + 3y = -5
-2x + 2y = 6
4x + 3y = -5
x = -3 + y
4(-3 + y) + 3y = -5
y = 1
x = -3 + 1
x = -2
(x, y) = (-2, 1)
Hope this helps!

Answer:
2√11
Step-by-step explanation:
The square of the hypotenuse (h) of the smaller triangle is given by the Pythagorean theorem:
h² = 6² +8² = 100
The length of x is given by that same theorem:
h² +x² = 12²
x² = 12² -h² = 144 -100 = 44 . . . . . subtract h², fill in its value
x = √44 . . . . . . . . take the square root
x = 2√11 . . . . . . . simplify the root
Answer:
Step-by-step explanation:
(8-5)/(1-0) = 3/1 = 3
y - 5 = 3(x -0)
y -5 = 3x - 0
y = 3x + 5
