Which of the following number lines represents the solution to x - 5 ≥ -2?
x - 5 ≥ - 2 represents a line with a close circle on 3 and going towards infinity.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, x - 5 ≥ - 2.
x ≥ - 2 + 5.
x ≥ 3.
This represents a line with a close circle on 3 and going towards infinity.

I will reward Brainliest
Answer:
x = 17
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
-243 = -9(10 + x)
Step 2: Solve for x
Divide -9 on both sides: 27 = 10 + xIsolate x: 17 = xRewrite: x = 17Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -243 = -9(10 + 17)Add: -243 = -9(27)Multiply: -243 = -243Here we see that -243 does indeed equal -243.
∴ x = 17 is the solution to the equation.

If Angle 3 were not included, the answer would be A, 360°
Step-by-step explanation: When the lines a, b, & c are parallel, the line intersecting them forms angles that are vertical, supplementary and/or corresponding and congruent.
Here, angles 4 and 5 are supplementary. No need to know their exact measurements. Together, their sum is 180°
Angles 1 and 2 are also supplementary, another 180°
But we don't know the measure of angle 3, so getting an exact sum is impossible here.

Solve the following system of equations:
y = 5/4x - 2
y = -1/4x + 19
x = ? and y = ?
Answer:
1. y= 5 /4 x −2
2.x=−4y+76
The value of a and y in the system y = (5/4)x - 2 and y = -(1/4)x + 19 are,
14 and 31/2 respectively.
What are the solutions of a linear system of equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given,
y = (5/4)x - 2 and y = -(1/4)x + 19.
Multiplying both the equations by 4 we have,
4y = 5x - 8 and 4y = - x + 76.
Subtracting the second equation from the first we have,
0 = 6x - 84.
6x = 84.
x = 14.
Replacing 'x' in any of the equations,
4y = 5(14) - 8.
4y = 70 - 8.
4y = 62.
y = 31/2.
