- 4:9::11/6
- => 4 x 6 = 9 x 11
- => 24 ≠ 99
This proves that this ratio is not proportional.
Answer:
1/3.
Step-by-step explanation:
The first thing to do is to get this equation in slope-intercept form. First divide both sides by 3, then simplify it down to slope intercept form ( 
):
Here, the slope is 1/3.

<span>Since we're dealing with a right triangle we can use Pythagoras' Theorem. So we have that x^2 = 6^2 + 4^2 <=> x^2 = 36 + 16 <=> x^2 = 52 <=> x = square root (52) <=> x = ~7.2.</span>
Answer:
4b³ + 11b² - 6b + 13
Step-by-step explanation:
Subtract like terms.
6b³ - 2b³ = 4b³
3b² - (-8b²) = 3b² + 8b² = 11b²
0 - 6b = -6b
8 - (-5) = 13
All together, the difference is 4b³ + 11b² - 6b + 13.
