Answer:

Step-by-step explanation:

Given that there are 15 people and they should be divided into two groups one with 10 and the other with 5 people.

First group 10 persons can be selected from 15 in 15C10 ways.

Remaining 5 would automatically be put in group 2.

Hence no of ways $= 15C5 =\frac{15!}[10!5!} \\=3003$

Cassidy wrote the linear equation y = 5 x + 4. Then, she wrote the equation of the line that is parallel to y = 5 x + 4 and that

Kryger [21]

Answer:

b=−5x+y

Step-by-step explanation:

Let's solve for b.

y=5x+b

Step 1: Flip the equation.

b+5x=y

Step 2: Add -5x to both sides.

b+5x+−5x=y+−5x

b=−5x+y

Will factor the express 36xyz + 24xy − 16x by dividing each term by a common fact

sesenic [268]

$\\ \bull\tt\longmapsto 36xyz+24xy-16x$

Divide by 4

$\\ \bull\tt\longmapsto \dfrac{36xyz}{4}+\dfrac{24xy}{4}-\dfrac{16x}{4}$

$\\ \bull\tt\longmapsto 9xyz+6xy-4x$

Divide by x

$\\ \bull\tt\longmapsto \dfrac{9xyz}{x}+\dfrac{6xy}{x}-\dfrac{4x}{x}$

$\\ \bull\tt\longmapsto 9yz+6y-4$

Solve the equation. (-7x + 2)^1/3 = (4 + 3x)^1/3

Brrunno [24]

(-7x + 2)^1/3 = (4 + 3x)^1/3
take the cube of both side to eliminate the 1/3 power
so you get
-7x+2=4+3x
combine like terms
-10x=2
solve for x
x=-1/5
