Apply distributive law
- a(b-d)=ab-ad
We can still take common
Find the equation of the line. Use exact numbers.
1 answer:
Answer:
y = x - 3
Step-by-step explanation:
Let the general equation of the line be y = ax + b
Note that the points (6,0) and (0,-3) lie on the line. That means, it should satisfy the equation of the line. We substitute the points on the equation of the line.
We would have:
From (2), we get: b = -3
From (1), we have -6a = b
Substituting b = -3, we get:
-6a = -3
⇒ a = 1/2
Therefore, the equation of the line would become: y = 1/2x - 3

<h2><u>Solution (1)</u> :</h2>
Given, to find A we have to :
- square m
- Add y to m²
- Subtract 7 from m² + y
From the question, the following equation can be formed :
Therefore, the formula for finding A = m² + y - 7
<h2><u>Solution (2)</u> :</h2>The value of A we can derive from the formula is :
Value of m = 3 (given)
Which means :
Thus, the value of A = 2+y
Therefore, the value of A = <u>2+y</u>
