Answer:

No solution l

<em><u>Solving steps:</u></em>

=> R + 3= (r - 5)

=> r - r + 3 = r - r - 5

=> 3 =  - 5

Step 1: <em><u>substra</u></em><em><u>c</u></em><em><u>t 3 from both </u></em><em><u>side</u></em>

=> <em><u>3 - 3 =  - 5 - 3</u></em>

<em><u>Step</u></em><em><u> </u></em><em><u>2</u></em><em><u>:</u></em><em><u> </u></em><em><u>S</u></em><em><u>ubtract 3 - 3 and -5 - 3</u></em>

=> 0 = - 8

<h3><em><u>Therefore this solution that have no </u></em><em><u>solution </u></em></h3><h3><em><u>Good luck and enjoy ^_^</u></em></h3>

Answer:

no solutions

Step-by-step explanation:

<u>Solving</u>

Step 1: Subtract 3 from both sides.

  • r+3-r=r-5-r
  • 3=-5

Step 2: Subtract 3 from both sides.

  • 3-3=-5-3
  • 0\neq -8

Therefore, there are no solutions to this equation.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Write the explicit formula for an, nth the term of the sequence 17,20,23
shepuryov [24]

Answer:  17+3(n-1)

This simplifies to 3n+14

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

Explanation:

a_1 = 17 is the first term

d = 3 is the common difference, or the gap between terms. Eg: the jump from 17 to 20 is +3.

This means the nth term is...

a_n = a_1 + d(n-1)\\\\a_n = 17+3(n-1)\\\\a_n = 17 + 3n-3\\\\a_n = 3n+14

As a check, if we tried something like n = 2, then,

a_n = 3n+14\\\\a_2 = 3*2+14\\\\a_2 = 20

which matches with the second term of the sequence your teacher gave you. I'll let you check the other terms.

Answer:

B) \sqrt{2} ÷ 2\sqrt{5}

Step-by-step explanation:

A→ 2\sqrt{5} ÷ \sqrt{5}

= \frac{2\sqrt{5} }{\sqrt{5} }

<u>→ </u><u>2</u><u> is a rational number</u>

B) → \sqrt{2} ÷ 2\sqrt{5}

=\frac{\sqrt{2} }{2\sqrt{5} }

=\frac{\sqrt{2} }{\sqrt{2}*\sqrt{2}*\sqrt{5}   }

= \frac{1}{\sqrt{10} }

<u>↑ is irrational number</u>

C) \frac{\pi }{2}÷ \pi

= \frac{\pi }{2} *\frac{1}{\pi }

=\frac{1}{2}

<u>↑ is a rational number</u>

D)5\pi ÷ \pi

= 5

<u>↑ is a rational number</u>

<u>So,</u><u> Option B</u><u> is your answer</u>

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

hope it helps..

have a great day!!!
