Answer:
The number of required shelves is 5
You have to find the HCF of 45, 105, and 75.
Answer:
The answer to your question is a) y - 2 = -5(x - 3)
b) y = -5x + 17
Step-by-step explanation:
Data
A (1, 12)
B (3, 2)
Process
1.- Find the slope
Formula

Substitution

2.- Find the equation in point slope form
Equation
y - y1 = m(x - x1)
Substitution and equation
y - 2 = -5(x - 3)
3.- Find the slope-intercept form
Expand the point slope form
y - 2 = -5x + 15
Simplify
y = -5x + 15 + 2
Equation
y = -5x + 17
Answer: No solution
<u>Step-by-step explanation:</u>
x - 3y = 2 → x = 3y + 2
2x - 6y = 6
2(3y + 2) - 6y = 6 <em>substituted x with 3y+2</em>
6y + 4 - 6y = 6 <em>distributed 2 into 3y+2</em>
4 = 6 <em>simplified (6y - 6y = 0)</em>
4 = 6 is a FALSE statement so there is NO SOLUTION
