A quadratic equation is any equation in the form of:

where a ≠ 0
Answer:4/3
Step-by-step explanation:
7 (x - 20)
use distribution method
7x - 140
Not similar, since the ratio of corespondent side is not constant
suppose ∆PRQ ~ ∆MRN, then RN/RP = RM/RQ but the reality contradict
<h2>Key Concepts</h2>
- Linear equations
- Slope-intercept form
Slope-intercept form looks like this:
- <em>m</em> = slope
- <em>b</em> = y-intercept
<h2>Solving the Question</h2>
We're given:
- <em>m</em> = 0
- <em>b</em> = -5
Plug the given values into y=mx+b:

<h2>Answer</h2>
