Answer:
y - 5 = -3(x - 12)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Point (12, 5)
Slope <em>m</em> = -3
<u>Step 2: Write Function</u>
<em>Plug in variables into the general formula.</em>
- Substitute [PSF]: y - 5 = -3(x - 12)
Answer:
a=6, b=-5
a=12, b=-5
Step-by-step explanation:
We have the equation
we will try to resolve for in terms of and
Then
Note that if the denominator is 0, then the division is undefined and therefore there would be no solution for x.
Then, the denominator is 0 if
.
Then, for the pairs
a=6, b=-5 and a=12, b=-5, there is no solution for x.
Answer:
Average decrease in car's value per year = 1800$
Explanation:
The worth of car bought by Mr. Solan = 30000$
Reduction of car's price = 5400$
Number of years considered for measuring reduction of car's price = 3 years.
Average of values = Total of the values/ Number of values.
Average reduction per year = Total reduction/ Number of years.
= 5400/3 = 1800$
So average decrease in car's value per year = 1800$
