Answer: The correct option is,

D. 3

Step-by-step explanation:

Here, the given equation,

\frac{6+8x}{2}=5x

Multiply both sides by 2,

6+8x = 10x

Subtract both sides by 8x,

6 = 2x

Divide both sides by 2,

3=x

Hence, the value of x in the given equation is 3.

Therefore, OPTION D is correct.

To solve for the value of x, you need to get rid of the fraction first, so you have to multiply each side of the original equation by 2, which will get you 6+8x=10x. Then, you subtract both sides by 8x, which will get you 6=2x. After that, you divide each side by 2, which leaves you with 3=x. So, the answer is D.3

Answer:

1: proportional

2: non-proportional

3: non-proportional

4: non-proportional

5: proportional

6: proportional

7: non-proportional

8: proportional

9. proportional.

10. proportional.

11. non-proportional.

12. proportional.

Step-by-step explanation:

I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.

The equation h=-16t^2 + 32t +9 gives the height of a ball, h, in feet above the ground, at t seconds after the ball is thrown up
Reil [10]
H = - 16 t² + 32 t + 9
The maximum height is at the vertex of the parabola:
t = - b / (2 a ) = - 32 : ( - 32 ) = 1 s
The ball will reach maximum height in 1 second.
h max = - 16 * 1² + 32 * 1 + 9 = - 16 + 32 + 9 = 25 m
The maximum height is 25 m.
