The solution to an inequality is graphed on the number line. What is another way to represent this solution set? O {x | X 4.5) O
x | x2 4.5) 5 -3 -2 -1 0 1 2 3 4 5
1 answer:
Answer: Choice B
=============================================
Explanation:
The endpoint is at 4.5 and this endpoint is a filled in circle. So we'll have "or equal to" as part of the inequality sign. This is because we are including the endpoint as part of the shaded solution region.
The other part of the inequality sign is "less than" because the shading is to the left of the endpoint. Any point in the shaded region is less than 4.5, or it could be equal to 4.5
Put another way: x is either 4.5 or smaller
We write that as which is read out as "x is less than or equal to 4.5"
Surrounding this in curly braces tells the reader we're dealing with a set of values. The first part "x |" means "x such that"
All together we end up with the answer which translates to "x such that x is less than or equal to 4.5"

Answer:
The correct option is option (c).
Step-by-step explanation:
Right angled triangle:
- One angle must be 90° and other two angles are acute angle.
- The hypotenuses is the longest side of the triangle and opposite right angle.
- It follows the Pythagorean Theorem.
Given that,
∠QRP= 90°, ∠RPQ= 30°, ∠PQR = 60°
we know that,
for sin P , the opposite is QR.
The hypotenuse is PQ.
Therefore,
Answer:
B. is exactly 1 triangle
Step-by-step explanation:
For any given triangle, the sum of the internal angles is . Thus from the given question, adding the given angles;
30° + 70° + 80° =
Therefore, only one triangle can be produced with the given measure of angles. This implies that there is exactly one triangle. So that the correct option is B.
