What are m and b in the linear equation 12 + 6x + 15 + 10x = y?
1 answer:
Answer:
<em>m</em> = 16
<em>b </em>= 27
General Formulas and Concepts:
<u>Algebra I</u>
Combining Like Terms
Slope-Intercept Form: y = mx + b
- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
12 + 6x + 15 + 10x = y
<u>Step 2: Simplify</u>
- Combine like terms (Z): 27 + 6x + 10x = y
- Combine like terms (x): 27 + 16x = y
- Rewrite: y = 16x + 27
<u>Step 3: Identify</u>
<em>Break apart functions.</em>
Slope <em>m</em> = 16
y-intercept <em>b</em> = 27

Answer:
50
Step-by-step explanation:
100 into 2 parts is 50
5x+100=10x
-5x on both sides (10x-5x=5x)
100=5x
divide by 5 on both sides (100/5= 20)
20=x
