Answer:
the answer is c.(3,-3)
:)
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
4) 3 for the numerator. 9 for the denominator
5) 6 for the first blank square and 48 for the second blank.
6) 2 for the denominator. 6 for the numerator. 30 for the second numerator.
Step-by-step explanation:
sorry but those are the only ones i know
Hope this helps!
-/7? imagine that there is an -1 as the numerator. so now -/7 turns into -1/7
Answer:
30
Step-by-step explanation:
x=6
4 by 6 =24
24 + 6 =30
A. C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.C(13, 10) = 13! = 13·12·11 = 13 · 2 · 11 = 286.
B. P(13,10)= 13! =13! =13·12·11·10·9·8·7·6·5·4.
(13−10)! 3!
C. f there is exactly one woman chosen, this is possible in C(10, 9)C(3, 1) =
10! 3!
9!1! 1!2!
10! 3!
8!2! 2!1!
10! 3!
7!3! 3!0!
= 10 · 3 = 30 ways; two women chosen — in C(10,8)C(3,2) =
= 45·3 = 135 ways; three women chosen — in C(10, 7)C(3, 3) =
= 10·9·8 ·1 = 120 ways. Altogether there are 30+135+120 = 285
1·2·3
