Step-by-step explanation:

Vẽ đồ thị y = 2x (1):

   Cho x= 0 ⇒ y= 0 ta được O (0, 0)

   Cho x= 2 ⇒ y = 4 ta được điểm (2; 4)

- Vẽ đồ thị y = 0,5x (2):

   Cho x= 0 ⇒ y = 0 ta được O (0; 0)

   Cho x = 4 ⇒ y = 2 ta được điểm (4; 2)

- Vẽ đồ thị y = -x + 6 (3):

   Cho x = 0 ⇒ y = 6 được điểm (0; 6)

   Cho y = 0 ⇒ x = 6 được điểm (6; 0)

Which expression is equivalent to StartFraction 2 a + 1 Over 10 a minus 5 Endfraction divided by StartFraction 10 a Over 4 a squ
dimaraw [331]

For this case we must simplify the following expression:

\frac {\frac {2a + 1} {10a-5}} {\frac {10a} {4a ^ 2-1}} =

We apply double C:

\frac {(4a ^ 2-1) (2a + 1)} {10a (10a-5)} =

We apply distributive property in the numerator and we take common factor 5 in the denominator:

\frac {8a ^ 3 + 4a ^ 2-2a-1} {10a (5 (2a-1))} =

We factor the numerator:

\frac {(2a + 1) ^ 2 (2a-1)} {10a (5 (2a-1))} =\\\frac {(2a + 1) ^ 2 (2a-1)} {50a (2a-1)} =

We simplify:

\frac {(2a + 1) ^ 2} {50a}

Answer:

\frac {(2a + 1) ^ 2} {50a}

Option D
