Answer:
Option C
Step-by-step explanation:
From the number line given in the picture,
Blue arrow has the starting point at a = 6 (Dark point) and moving towards negative side of the number line.
Therefore, number line represents a ≤ 6
3a ≤ 3(6)
3a ≤ 18
3a - 11 ≤ 18 - 11
3a - 11 ≤ 7
Therefore, Option C is the correct option.
Answer:
86.7%
Step-by-step explanation:
40/300 * 100% is 13.3%, 100%-13.3% is 86.76%
(3 is repeating)
Answer:
5 < x < 13
Step-by-step explanation:
9+4 > x
4 + x > 9
To solve this problem you must apply the proccedure shown below:
1. You have the following parametric equations given in the problem above:
<span> x=e^3t
y=e^-t</span>
2. Therefore, you must solve fot et in the second equation, as below:
y=e^-t
y=1/e^t
e^t=1/y
3.Substitute into the first equation:
x=e^3t
x=(e^t)^3
x=(1/y)^3
x=1/y^3 (y>0)
The answer is: x=1/y^3 (y>0)
All you have to do is multiple 18 times 3 which is 54.
