So 10/2 simplified is 5/1 which is on point 5. -9/2 is already simplified so in decimal form it is -4.5 which is -4 1/2, so you go down from 0 and mark it right where the BLUE dot is and the GREEN dot is 5/1. Hope this helps! :)

Answer:
C and E
Step-by-step explanation:
We are given that
A.
Hence, it is not in proportional relationship with (0.2,0.3)
B.(2.7,4.3)
Hence, it is not in proportional relationship with (0.2,0.3).
C.(3.2,4.8)
Hence, the ordered pair (3.2,4.8) are in a proportional relationship with (0.2,0.3).
D.(3.5,5.3)
Hence, the ordered pair (3.5,5.3) are not in a proportional relationship with (0.2,0.3).
E.(5.2,7.8)
Hence, the ordered pair (5.2,7.8) are in a proportional relationship with (0.2,0.3).
Answer:
(3 + 4x)(9 - 12x + 16x²) = 0
(4m - 1)(16m² + 4m + 1) = 0
Step-by-step explanation:
Here we have to solve the sum of two cubes which is
Now, the equation is
⇒ 3³ + (4x)³ = 0
⇒ (3 + 4x)[3² - 3(4x) + (4x)²] = 0
⇒ (3 + 4x)(9 - 12x + 16x²) = 0
So, (3 + 4x) = 0 or (9 - 12x + 16x²) = 0
Therefore, from the above two relation we can solve for x.
One root will be and the others we will get by applying Sridhar Acharya Formula, which will give a pair of conjugate imaginary roots of the equation.
Again, we have to solve the difference of two cubes which is
Now, the equation is
⇒ (4m)³ - 1³ = 0
⇒ (4m - 1)[(4m)² + 4m(1) + 1²] = 0
⇒ (4m - 1)(16m² + 4m + 1) = 0
So, (4m - 1) = 0 or (16m² + 4m + 1) = 0
Therefore, from the above two relation we can solve for m.
One root will be and the others we will get by applying Sridhar Acharya Formula, which will give a pair of conjugate imaginary roots of the equation. (Answer)
