Answer:

6%

Step-by-step explanation:

6 divided by 100 is 0.06.

then you multiply 0.06 by 135 and that is 8.1

then add 8.1 to 135 and you get 143.1 or 143.10

The board of a large company is made up of 7 women and 9 men. 6 of them will go as a delegation to a national conference.
Burka [1]

Answer:

a) 5765760

b) 60480

c) 5705280

Step-by-step explanation:

Assuming that order is not important:

Number of women = 7

Number of men = 9

Members of the delegation = 6

a) How many delegations are possible?

n=\frac{16!}{(16-6)!}=16*15*14*13*12*11\\ n= 5765760

b) How many of these delegations have all men?

n_{men} = \frac{9!}{(9-6)!}=9*8*7*6*5*4  \\n_{men} = 60480

c) How many of these delegations have at least one woman?

n_{women >0}=n-n_{men}\\n_{women >0} =5765760-60480\\n_{women >0} =5705280

Solve the system of equations using substitution
Ira Lisetskai [31]

Answer:

x=-1, y=9. (-1, 9).

Step-by-step explanation:

6x-y=-15

x+2y=17

--------------

y=6x-(-15)

y=6x+15

x+2(6x+15)=17

x+12x+30=17

13x=17-30

13x=-13

x=-13/13

x=-1

-1+2y=17

2y=17-(-1)

2y=17+1

2y=18

y=18/2

y=9

what is the equation of the line, in slope-intercept form, that contains the points (−1, 2) and (2, −1)?
Ierofanga [76]
The\ slope-intercept\ form:y=mx+b\\\\The\ slope-point\ form:y-y_1=m(x-x_1)\\\\The\ slope:m=\dfrac{y_2-y_1}{x_2-x_1}\\---------------------\\(-1;\ 2);\ (2;-1)\\\\m=\dfrac{-1-2}{2-(-1)}=\dfrac{-3}{3}=-1\\\\y-(-1)=-1(x-2)\\y+1=-x+2\ \ \ |subtract\ 1\ from\ both\ sides\\\boxed{y=-x+1}
