Answer:

The

number 2

Step-by-step explanation:

What we need here is just the sign of the discriminant

From the question in this case, the discriminant is positive

Thus, whenever we have a positive discriminant, then the number of real solution is 2 and these two are distinct (different from one another).

Answer:

18/20 is closer to 1

Step-by-step explanation:

Answer:

0 1/2

Step-by-step explanation:

Answer:

The answer is 13

Step-by-step explanation:

First, you replace x with 2. Then you multiply 4 and 2 which you get 8. Lastly, you add 8 and 5 so you get 13.

Answer: Their is 5 seats in 1 row.

Step-by-step explanation:    9x5=45 and 45÷9=5

Answer:

vertex angle = 180° - 2x

Step-by-step explanation:

Since, the measure of each base angle of an isosceles triangle is represented by x.

So, by interior angle sum postulate of a triangle, we have:

x + x + vertex angle = 180°

2x + vertex angle = 180°

vertex angle = 180° - 2x

So, the vertex angle is represented by (180° - 2x).

Answer:

use cross multiplication to solve

4*7 = 2*x (multiply)

28 = 2x (divide both sides by 2 to isolate x )

x = 14 (your answer)

Answer:

13 tables

Step-by-step explanation:

156 ÷ 12 = 13

156 people divided by the number of people each table hold will give u the amount of tables needed

Step-by-step explanation:. The first says “I know that 10 is one-tenth of 100. I will therefore divide 50 by 10. The answer is 5”.

This is fine when the numbers are relatively simple. But suppose the numbers are more complicated.

What is 22% of 46?

Now it’s much less straightforward. You can’t just work out what 22% is, expressed as a fraction, and anyway, it’s not a simple fraction.

Instead, you have to divide 46 into 100 equal parts, and work out what 22 of them would be when added together.

So: 46 ÷ 100 = 0.46 [remember, when you divide by 100, you move the decimal point two places to the left].

0.46 × 22 = 10.12

Answer: 22% of 46 is 10.12.

Hope this helped :)

Answer:

We conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

Step-by-step explanation:

Given

as

[tex]\:\sqrt{21}=4.58[/tex]

and

[tex]4\frac{2}{3}[/tex]

Convert mixed numbers to improper fraction:

[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]

so

[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]

Thus,

[tex]\:\sqrt{21}=4.58[/tex]

[tex]4\frac{2}{3}=4.67[/tex]

as

4.67      >       4.58

so

[tex]4\frac{2}{3}[/tex]         >        [tex]\sqrt{21}[/tex]

Hence, we conclude that

[tex]4\frac{2}{3}[/tex]    >   [tex]\sqrt{21}[/tex]

Answer:

3x and 8x are like terms.

Step-by-step explanation:

Like terms are the terms that share the same variables. They do not have to share the same coefficients - or, in other words - the numbers in front of the variable do not have to be the same. Only the variable has to match.

So, looking at the expression, the only two terms that have the same variable are 8x and 3x, which both have the variable x. Therefore, 3x and 8x are like terms.

Answer:

probably cuz its in parentheses but there's no picture

Step-by-step explanation:

Answer:

130%

increase

Step-by-step explanation:

the new quantity is 13, the old is 10

divide 13/10

in your calculator this will show 1.3

that means one whole and 30/100ths, or in percents 130%

(to convert decimal to percent just mulitply by 100)

Answer: 4K chains

Step-by-step explanation:

Answer:

If your good at math plz help me

i think this is the answer, hope A(-3)=n-5

==================================================

Work Shown:

[tex]a_1 = -3 = \text{ first term}\\\\d = -5 = \text{ common difference}\\\\a_n = a_1 + d(n-1) = \text{ nth term}\\\\a_n = -3 + (-5)(n-1)\\\\a_n = -3 -5n + 5\\\\a_n = -5n + 2\\\\[/tex]

The common difference is due to us adding -5 to each term to get the next one. Example: -3+(-5) = -8, or -8+(-5) = -13.

--------------------

As a way to check if we have the correct nth term formula, plug in values of n to see if we get the correct sequence value

For instance, if n = 1, then

[tex]a_n = -5n+2\\\\a_1 = -5(1)+2\\\\a_1 = -5+2\\\\a_1 = -3\\\\[/tex]

Which matches with the first term given to us.

Or if n = 2, then,

[tex]a_n = -5n+2\\\\a_2 = -5(2)+2\\\\a_2 = -10+2\\\\a_2 = -8\\\\[/tex]

That matches the second term given to us. I'll let you check the others.
