Answer:

x = -3

Step-by-step explanation:

First we take the equation below.

4 - 2x = 10

Subtract 4 from each side because of the subtraction property of equality.

-2x=6

Divide both sides by -2 to isolate the x. (Division property of equality

x=-3

We now know that x = -3.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

The correct option is A.

<h3>What is a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

The slope of the parallel line is always equal. Given the slope of the green line is -3/7, also, it is parallel to the red line. Therefore, the slope of the red line is -3/7.

Hence, the correct option is A.

By what least number should 4851 be divided to get a perfect square number ? Also find the square root of the square number so o
beks73 [17]

Answer:

The least number should 4851 be divided to get a perfect square number = 11

The square root of the obtained perfect square number is 21

Step-by-step explanation:

Given number = 4851

It can be written as

4851 = 3×1617

4851 = 3×3×539

4851 = 3×3×7×77

4851 = 3×3×7×7×11

4851 = (3×3)×(7×7)×11

It is clear that We should divide the given number by 11 then we get a perfect square number.

4851/11 = 441

441 = 21×21

=> 441 = 21²

=> √441 = √(21²)

=> √441 = 21

<h3><u>Answer:-</u></h3>

The least number should 4851 be divided to get a perfect square number = 11

The square root of the obtained perfect square number is 21

<h3><u>Used Method :-</u></h3>

→ Prime Factorization Method

If there are x teams in a sports​ league, and all the teams play each other​ twice, a total of​ n(x) games are​ played, where ​n
EleoNora [17]
1.
Consider a group of n objects. Assume we want to form groups of r, from these n objects.

There are in total C(n, r)= \frac{n!}{r!(n-r)!} many ways of doing so.

where, r! is "r factorial", calculated as 1*2*3*...*(r-1)*r

2.

C(x, 2) is the total number of pairs out of x objects, that we can form.

so let the x objects represent the x teams, and 2, represent a group of 2, which means a game.

The total number of games is:

n(x)=2*C(x, 2) = 2*  \frac{x!}{2!(x-2)!}= \frac{x!}{(x-2)!}= \frac{x(x-1)(x-2)!}{(x-2)!}=x(x-1)= x^{2} -x

Remark, we multiplied by 2, since there will be 2 matches for each pair of teams.


Answer: x^{2} -x
