Step-by-step explanation:
<u>Step 1: Define</u>
-84 = -2(2 + 5k)
<u>Step 2: Solve for </u><em><u>k</u></em>
- Divide -2 on both sides: 42 = 2 + 5k
- Isolate <em>k</em> term: 40 = 5k
- Isolate <em>k</em>: 8 = k
- Rewrite: k = 8
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: -84 = -2(2 + 5(8))
- Multiply: -84 = -2(2 + 40)
- Add: -84 = -2(42)
- Multiply: -84 = -84
Here we see that -84 does indeed equal -84.
∴ k = 8 is the solution to the equation.
<h2>question :</h2>
40. which of the following equation graphs as a vertical parallel to the y-axis?
41. if ΔABC = ΔFGH, then which of the following statements is not necessarily true?
<h2>my answer :</h2>
40. the meaning of "vertical parallel to the y-axis" is a line that is perpendicular to the x-axis
then the equation that can be written parallel to the line y is x = a, a is the distance from point 0.
(*the second choice is correct)
41. if ΔABC = ΔFGH, it can be said that the second triangle of the shape is congruous (*in the picture)
(*the second choice is correct)
Answer:
Yes, π/12 is a solution.
Step-by-step explanation:
Calculator --> sin(π12)=sin15∘=0.26 . √2−√32=√0.272=0.522=0.26 . Uhmm... i dont rlly know how to explain it.. its complicated for me to word it without making it non confusing.
