−3 Which is the correct graph for the compound inequality
The correct graph for the compound inequality is the third graph.
Graph of Inequality
From the question, we are to determine the correct graph to the given compound inequality
The given compound inequality is
-3 < x ≤ 4
This means
-3 < x and x ≤ 4
That is,
x > -3 and x ≤ 4
The graph of x > -3 will start at -3 on the number line without shading the circle and it will point in the right direction
The graph of x ≤ 4 will start at 4 on the number line, with the circle shaded, and it will point towards the left
Joining the two graphs, we will get a number line starting at -3, unshaded, and ending at 4 shaded.
Hence, the correct graph for the compound inequality is the third graph.

Which pair of triangles can be proven congruent by the HL theorem?
2 right triangles have congruent hypotenuses.
2 triangles have one congruent angle and 2 congruent sides.
2 right triangles have congruent hypotenuses and another congruent side.
2 triangles have 3 congruent sides.
The pair of triangles that can be proven congruent by the HL theorem is: C. 2 right triangles having a pair of congruent hypotenuses and a pair of congruent side.
What is the HL Theorem?The HL theorem is a triangle congruence theorem which states that two right triangles are congruent to each other, if the hypotenuse of one is congruent to the hypotenuse, and also if one leg of one right triangle is congruent to a corresponding leg in the other right triangle.
Thus, if two triangles are right triangles having a pair of congruent hypotenuses and another pair of congruent side, then they are congruent by the HL theorem.
In conclusion, the pair of triangles that can be proven congruent by the HL theorem is: C. 2 right triangles having a pair of congruent hypotenuses and a pair of congruent side.

The sum of thirteen and twice a number. Is it linear or nonlinear?
HLP
The expression for the statement "the sum of thirteen and twice a number" will be given by 13 + 2 x.
We are given a statement:
The sum of thirteen and twice a number.
We need to make an expression for the statement that is being given to us.
Now, first we will let the unknown number be x.
So, twice of a number x will be written as:
2 × x
= 2 x
Now the sum of 13 and 2 x will be written as:
13 + 2 x
Therefore, we get that, the expression for the statement "the sum of thirteen and twice a number" will be given by 13 + 2 x.

Point P is located 3/5 of the way from point A to point E. Point A is located at (-1, -1) and point P is located
at (-7,5). What are the coordinates for point E?
By using the line segment formula, we conclude that the coordinates of point E are E(x, y) = (- 11, 9).
How to determine the coordinates of the missing endpoint of a line segment
In this problem we find a line segment of which the coordinates of an endpoint and a point within the segment and in accordance with a segment ratio are known. The coordinates of the other endpoint must be found in accordance with the following expression:
E(x, y) = A(x, y) + k · [P(x, y) - A(x, y)] (1)
Where E(x, y) is the missing endpoint.
If we know that A(x, y) = (- 1, - 1), P(x, y) = (- 7, 5) and k = 5 / 3, then the coordinates of point E are:
E(x, y) = (- 1, - 1) + (5 / 3) · [(- 7, 5) - (- 1, - 1)]
E(x, y) = (- 1, - 1) + (5 / 3) · (- 6, 6)
E(x, y) = (- 1, - 1) + (- 10, 10)
E(x, y) = (- 11, 9)

The combined debt of the three most populous states is -2 × 10⁹ bigger than that of the three least populous states.
What is the arithmetic operator?Summarization, subtraction, division, and multiplication are the four fundamental mathematical operations covered under the term "arithmetic operators."
Given the combined debt of ;
Most populous = -1.02 × 10¹⁰
Least populous = -1 × 10¹⁰
Most populous - Least populous ⇒
( -1.02 × 10¹⁰) - (-1 × 10¹⁰)
⇒ -0.2 × 10¹⁰
Multiply and divide by 10
⇒ -0.2 × 10/10 × 10¹⁰
⇒ -2 × 10¹⁰/10
⇒ -2 × 10⁹
Hence "The combined debt of the three most populous states is -2 × 10⁹ bigger than that of the three least populous states".
