4 = + 8 + 2t solve for t

1 answer:

3 0

T= 2

Explanation:

Since this equation has a positive answer u will have to take away.

So 8-2 which is 6. Since the answer gives us a 4. We do 6-4 which is 2. And bc of this answer it proves that t is 2.

Hope this helps!

If the square root of p2 is an integer greater than 1, which of the following must be true? I. p2 has an odd number of positive

Grace [21]

Answer:

Option | and Option || is True

Step-by-step explanation:

Given:

If the square root of $p^{2}$ is an integer greater than 1,

Lets p = 2, 3, 4, 5, 6, 7..........

Solution:

Now we check all option for $p^{2}$

Option |.

$p^{2}$ has an odd number of positive factors.

Let $p=2$

The positive factor of $2^{2}=4=1,2,4$

Number of factor is 3

Let $p=3$

The positive factor of $3^{2}=9=1,3,9$

Number of factor is 3

So, $p^{2}$ has an odd number of positive factors.

Therefore, 1st option is true.

Option ||.

$p^{2}$ can be expressed as the product of an even number of positive prime factors

Let $p=2$

The positive factor of $2^{2}=4=1,2,4$

$4=2\times 2$

Let $p=3$

The positive factor of $3^{2}=9=1,3,9$

$9=3\times 3$

So, it is expressed as the product of an even number of positive prime factors,

Therefore, 2nd option is true.

Option |||.

p has an even number of positive factors

Let $p=2$

Positive factor of $2=1,2$

Number of factor is 2.

Let $p=4$

Positive factor of $4=1,2,4$

Number of factor is 3 that is odd

So, p has also odd number of positive factor.

Therefore, it is false.

Therefore, Option | and Option || is True.

Option ||| is false.

Draw a line representing the “rise” and a line representing the “run” of the line. State the slope of the line in simplest form.

Oksanka [162]

The slope of the line in its simplest form is 3.

The slope of a line is $Slope=\frac{Rise}{Run}$ .

We need to find the slope of the line in its simplest form.

<h3>What is the slope?</h3>

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope is often denoted by the letter m; there is no clear answer to the question of why the letter m is used for slope.
