Answer:

We are given

[tex]( \sqrt{3} + \sqrt{7} )( \sqrt{7} - \sqrt{3} )[/tex]

Answer:

4

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex] and [tex]\sqrt{a}[/tex] × [tex]\sqrt{a}[/tex] = a

Given

([tex]\sqrt{3}[/tex] + [tex]\sqrt{7}[/tex] )([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] )

Each term in the second factor is multiplied by each term in the first factor, that is

[tex]\sqrt{3}[/tex] ([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] ) + [tex]\sqrt{7}[/tex] ([tex]\sqrt{7}[/tex] - [tex]\sqrt{3}[/tex] ) ← distribute both parenthesis

= [tex]\sqrt{21}[/tex] - 3 + 7 - [tex]\sqrt{21}[/tex] ← collect like terms

= 4

Answer:

t(n) = -7.1 - 2.1n

t(27) = -7.1 - 2.1(27)

t(27) = -7.1 - 56.7

t(27) = -63.8

for the n term 1,2,3,4,5 you can use it like previous I have done

Answer:

y = -7x + 1

Step-by-step explanation:

You put it in the form y = m*x + b

Where m = the slope, so -7 and b = the y-intercept, so 1.

This means it's y = -7x + 1

Note: this answer assumes the equation can be put in slope-intercept form.

Answer:

y = -7x + 1

Step-by-step explanation:

Slope-intercept form, or y = mx + b format, is written in a way that easily reflects the slope and y-intercept of a line. The m, or the coefficient of the term with the x, represents the slope. The b represents the y-value of the y-intercept.

Therefore, substitute the number -7 and 1 in place of those variables. Since -7 is the slope, substitute in place for m. Since 1 is the y-intercept, substitute in place of b. This gives us the equation y = -7x + 1.

D, John did not make a mistake!

Step-by-step explanation:

Answer:

No Solution

Step-by-step explanation:

For system of equations, you must equal the equations to each other like shown below:

[tex]3x + 1 = 3x + 7[/tex]

Solve for x by subtracting 3x from both sides of the equation:

[tex]1[/tex] ≠ [tex]7[/tex]

Answer:

Step-by-step explanation:

The fraction that is boys is 5/(5+4) = 5/9. That fraction of the total is ...

  boys = 5/9 × 171 = 95

Girls are the remainder:

  girls = 171 -95 = 76

There are 95 boys and 76 girls in the band.

Answer:

$15 dollars left after you purchased everything except the purse.

Step-by-step explanation:

5+10+25=40

65-40=15

if you have $15 left it depends on how much the purse costs.

Say it costs $10 dollars you would have $5 left and so on

Answer:

the time taken for having 1 million bacteria is 137.68 hours  

Step-by-step explanation:

The computation is shown below:

y = 2 × (1.10)^x

1,000,000 = 2 × (1.10)^x

500,000 = (1.10)^x

x = log (500,000) ÷ log (1.10)

= 137.68 hours

hence the time taken for having 1 million bacteria is 137.68 hours

Step-by-step explanation:

Answer:

The answer is the second table (the one with B and C.)

Step-by-step explanation:

You know this, because the other tables are just based on patterns and the x and y values have nothing to do with each other. However, for the second table, the b value times 3 equals the c value. This is how you know the table shows a proportional relationship, and this is key to solving this problem.

Here's an image that helps demonstrate this idea:

Answer:

[tex]3\frac{1}{2} hours[/tex]

Step-by-step explanation:

You have to subtract 2 1/2 from 6 and that will equal 3 and 1/2.

Answer:

75%

Step-by-step explanation:

6 - 3/2 is 4.5.

So the computer has 4.5 hours.

the battery will last for 6 hours so every hour on the computer is 100/6 percentage, which is 16.6666666667.

Finally multiply 16.6666666667 and 4.5 and you will get 75%

Your final answer would be 75%

★ Input of the given function F(x) is 5.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

✯ F(x) = 7x - 9

✯ Output = 26

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

According to the question the output is 26.

Hence, the above data can be written in an equation form.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ F(x) = 7x - 9 = 26

➪ 7x = 26 + 9

➪ 7x = 35

➪ [tex]\sf x = \dfrac{35}{7}[/tex]

➪ [tex]\bold\red{x = 5}[/tex]

Therefore, F(x) = 5
