C(10,4)×C(11,6) = 210×462 = 97,020

_____
Any of the choices of 4 of 10 men can be combined with any of the choices of 6 of 11 women. The "n choose k" function, C(n, k) is computed as n!/(k!×(n-k)!).

F(x) = 2x+6, g(x) = 3² findf(g (-3))​
Yanka [14]

Answer:

➩ f(g(-3)) = 24

Step-by-step explanation:

➨ Rearrange/Simplify the equations

F(x)=2x+6\\g(x)=9

➨ Find f(g(-3))

g(-3)=9 ➩ All x-values have same y-values ➩ Constant Function

Substitute g(-3) = 9 in the f(x)

f(g(-3)) = f(9)\\f(9)=2(9)+6\\f(9)=18+6\\f(9)=24\\f(g(-3)) = 24

Thus, the answer ➩ f(g(-3)) = 24

Solve for x given BD = 4x+3 and AE = 4x+8. Assume B is the midpoint of segment AC and D is the midpoint of segment CE.
wolverine [178]

Answer: The fraction x = 1/2 or its equivalent decimal form x = 0.5

================================================

Work Shown:

AE = 2*(BD)

4x+8 = 2*(4x+3)

4x+8 = 8x+6

8-6 = 8x-4x

2 = 4x

4x = 2

x = 2/4

x = 1/2

x = 0.5

note: the first equation is set up basically saying that AE is twice that of BD; put another way, BD is half as long as AE. This is one property of midsegments. Another property is that AE and BD are parallel.

another note: if x = 0.5, then AE = 4*x+8 = 4*0.5+8 = 10 while BD = 4*x+3 = 4*0.5+3 = 5, showing that AE is indeed two times longer than BD.
