General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Algebra I

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

Step 1: Define systems

-5x - 3y = 12

y = x - 12

Step 2: Solve for x

Substitution

Substitute in y: -5x - 3(x - 12) = 12
Distribute -3: -5x - 3x + 36 = 12
Combine like terms: -8x + 36 = 12
Isolate x term: -8x = -24
Isolate x: x = 3

Step 3: Solve for y

Define original equation: y = x - 12
Substitute in x: y = 3 - 12
Subtract: y = -9

Step 4: Graph systems

Check the solution set.

A salsa recipe uses green pepper, and onion, and tomato in the extended ratio 2:5:9. How many cups of onion are needed to make 9

Vlad1618 [11]

The answer is 30 cups

Let x be a multiplier. So:
2x + 5x + 9x = 96
16x = 96
x = 96/16
x = 6 cups

Since the number of onion cups is 5x, then 5 * 6 = 30 cups are needed to make 96 cups of salsa.

Let f(x)=2x+2. Solve f^-1(x) when x=4

Gre4nikov [31]

F⁻¹(x) stands for the invers of function f(x). The inverse of f(x) is equal to x. We need to solve for x.

solve for x
f(x) = 2x + 2
2x + 2 = f(x)
2x = f(x) - 2
x = $\dfrac{f(x)-2}{2}$
f⁻¹(x) = $\dfrac{x-2}{2}$

Determine the value of f⁻¹(x) when x = 4
f⁻¹(x) = $\dfrac{x-2}{2}$
f⁻¹(4) = $\dfrac{4-2}{2}$
f⁻¹(4) = $\dfrac{2}{2}$
f⁻¹(4) = 1
When x = 4, the value of f⁻¹(x) is equal to 1
