Which equations have the same pair of solutions? Select all that apply. n(n + 3)(n - 4) = 0 2n(4n + 6)(6n - 4) = 0 0 = 2n(6 - 4n)(4 - 6n) 0 = n(2n + 3)(3n - 2) 2n(2n + 3)(3n - 2) = 0 3n(6n + 9)(9n - 6) = 0

Answers

Answer:

2,4,5,6

Step-by-step explanation:

$n=0,4n+6=0\implies n=-(6)/(4)=-(3)/(2)$

$6n-4=0\implies n=(4)/(6)=(2)/(3)$

n=0, $n=-(3)/(2),n=(2)/(3)$

3. $2n(6n-4)(4-6n)=0$

n=0

$6n-4=0$

$n=(4)/(6)=(2)/(3)$

$4-6n=0$

$n=(4)/(6)=(2)/(3)$

4. $n(2n+3)(3n-2)=0$

$n=0$

$2n+3=0$

$n=-(3)/(2)$

$3n-2=0$

$n=(2)/(3)$

5. $2n(2n+3)(3n-2)=0$

$n=0$

$2n+3=0$

$n=-(3)/(2)$

$3n-2=0$

$n=(2)/(3)$

6. $3n(6n+9)(9n-6)=0$

$n=0$

$6n+9=0$

$n=(-9)/(6)=-(3)/(2)$

$9n-6=0$

$n=(6)/(9)=(2)/(3)$

Answer:2,4,5 and 6 equation have same solutions.

Answer:

2, 4, 5, and 6 have the same pair of solutions.

Step-by-step explanation:

1. n(n+3)(n-4) = 0

2. 2n(4n+6)(6n-4) = 0

3. 2n(6-4n)(4n-6n) = 0

4. n(2n+3)(3n-2) = 0

5. 2n(2n+3)(3n-2) = 0

6. 3n(6n+9)(9n-6) = 0

Answers:

1. n = 0, -3, 4

2. n = 0, -3/2, 2/3

3. n = 0, 3/2

4. n = 0, -3/2, 2/3

5. n = 0, -3/2, 2/3

6. n = 0, -3/2, 2/3

Solve the equation, first for x and then for y.

Answers

Answer:

x = 77 - 2y

y = -x/2 + 77/2

Step-by-step explanation:

2x + 4y - 31 = 123

add 31 both sides

2x + 4y - 31 + 31 = 123 + 31

2x +4y = 154

Solve for x

2x = 154 - 4y

divide both sides by 2

x = 77 - 2y

solve for y

2y = 77 - x

divide both sides by 2

y = 77/2 - x/2

$8,200
$6,200
$4,240
$4,420
None of these

Answers

he receives 8.5% commission on sales from $70,000 to $100,000, therefore the commission is:
comission = 8.5%($82000) = (85/1000)(82000)
= 6979
that is his commission
