The expression 2x means 2 times x.
It also means x plus x.

These are appropriate descriptions:

2: The expression represents 5 plus 2 times x.
3: The expression represents 5 plus x plus x.
5: The expression represents the sum of 5 and 2x.

IRISSAK [1]

F(x) = x+4
f(4) = 8, f(5) = 9
Change = 1

f(x) = 3x-7
f(-3) = -16, f(5) = 8
Change = 24/8 = 3

f(x) = 9x+1
f(-5) = -44, f(-2) = -17
Change = 27/3 = 9

f(x) = 2x+9
f(1) = 11, f(2) = 13
Change = 2

In order: f(x) = 9x+1, f(x) = 3x-7, f(x) = 2x+9, f(x) = x+4

Answer:

(5, 9)

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Left to Right

Equality Properties

Multiplication Property of Equality
Division Property of Equality
Addition Property of Equality
Subtract Property of Equality

Algebra I

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

x - 5y = -40

18x - 5y = 45

Step 2: Rewrite Systems

18x - 5y = 45

Multiply both sides by -1: -18x + 5y = -45

Step 3: Redefine Systems

x - 5y = -40

-18x + 5y = -45

Step 4: Solve for x

Elimination

Combine equations: -17x = -85
Divide -17 on both sides: x = 5

Step 5: Solve for y

Define equation: x - 5y = -40
Substitute in x: 5 - 5y = -40
Isolate y term: -5y = -45
Isolate y: y = 9
