Answer:
<em>m</em> = 4/5
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define Equation</u>
y = 4/5x - 3
<u>Step 2: Break Function</u>
<em>Identify Parts</em>
Slope <em>m</em> = 4/5
y-intercept <em>b</em> = -3
Angles are always congruent
Y = 2x - 2.25 y = 10
10 = 2x - 2.25
10 + 2.25 = 2x
12.25 = 2x
6.125 = x
hope this helps, God bless!
First, we subtract 20% of the amount from x, so the initial cost of the furniture should be 80% of x or 0.80x. Then, due to the sales taxs, this amount should be added with 6.25% of itself. Such that,
A = 0.80x + 0.0625(0.80x)
= 0.85x
