Answer:
|1| = 1
|-4| = 4
|-3| = 3
|2| = 2
Step-by-step explanation:
The absolute value function is defined by
Since 1>0, we have |1| = 1.
Since -4<0, we have |-4| = -(-4) = 4.
Since -3<0, we have |-3| = -(-3) = 3.
Since 2>0, we have |2| = 2.

General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
- Solving systems of equations by graphing
Step-by-step explanation:
<u>Step 1: Define systems</u>
y = x + 1
y = 1/2x + 3
<u>Step 2: Solve for</u><u><em> x</em></u>
- Substitute in <em>y</em>: x + 1 = 1/2x + 3
- Subtract 1/2x on both sides: 1/2x + 1 = 3
- Subtract 1 on both sides: 1/2x = 2
- Divide both sides by 1/2: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x + 1
- Substitute in <em>x</em>: y = 4 + 1
- Add: y = 5
<u>Step 4: Graph</u>
<em>We can confirm our answer.</em>

Answer:
Current debt of Andrea = $7,150
Step-by-step explanation:
Given:
Loan taken by Andrea from bank = $25,850
Amount paid by Andrea to bank = $18,700
Find:
Current debt of Andrea
Computation:
⇒ Current debt of Andrea = Loan taken by Andrea from bank - Amount paid by Andrea to bank
⇒ Current debt of Andrea = 25,850 - 18,700
Current debt of Andrea = $7,150
Note: O information provide about interest.
Answer:
equation of a line:
y = mx+c
1) find the gradient, m
2) find y-intercept, c using coordinate (1,-4)
y = mx + c
-4 = 0(1) + c
c = -4
the equation of line:
y = mx+c
y = 0(x) + c
y = c
y = -4
