Step-by-step explanation:
<u>Step 1: Define</u>
-5x - 1 ≤ -9
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 1 to both sides: -5x ≤ -8
- Divide -5 on both sides: x ≥ 8/5
Here we see that any value <em>x</em> greater than or equal to 1.6 would work as a solution.
Therefore, our answer is A. 1, as it doesn't work as a solution.
Answer:
y=1, x=1
Step-by-step explanation:
This is a 90-45-45 triangle. One side is a sq root 2, and the other sides are a and a.
For example, if one side was 3 sq root two, then the other sides would be 3 and 3
Since beta is in the first quadrant, the final answer will be positive.
To find cos(beta) so we can use the half angle identity, we can substitute into the Pythagorean identity. Doing so gives us that
So, this means that
