Is the equation conditional, an identity, or a contradiction? y - 11 + 3y = 6y + 4

Mathematics
1 answer:
ipn [44]3 years ago
8 0

Answer:

The equation is a conditional.

y = 7.5

Step-by-step explanation:

y - 11 + 3y = 6y + 4

4y - 11 = 6y + 4

4y - 4y - 11 = 6y - 4y + 4

- 11 = 2y + 4

- 11 - 4 = 2y + 4 - 4

2y = - 15

2y ÷ 2 = - 15 ÷ 2

y = - 7.5

Find 4 geometric means between -5 and -125.
balandron [24]

The geometric means between -5 and -125 is; 25

<h3>How to find the geometric mean?</h3>

To find the geometric mean between two numbers, we simply find the square root of the product of the two numbers.

For example, geometric mean between A and B is;

G.M = √(A * B)

Thus, geometric mean between -5 and -125 is;

G.M = √(-5 * -125)

G.M = √625

G.M = 25

There could be other geometric means between this like;

G.M = √(-5 * -45) = 15

Or GM = √(-10 * -40) = 20

The class has n students, and n is an even number. The students are forming teams to work on their homework. Each team has exact
yuradex [85]

Answer:

Distinct ways  in which they all can form the teams for the class = n(n-1)

Step-by-step explanation:

Total numbers of students = n (even number)

Number of student in each team = 2

Number of distinct ways are there to form the teams for the class:

P^{n}_{k}=\frac{n!}{(n-k)!}

where = n = number of elements  = n

k = number of elements choose = 2

P^{n}_{2}=\frac{n!}{(n-2)!}=\frac{n\times (n-1)\times (n-2)!}{(n-2)!}

=n\times (n-1)
