The value of x from the given equation is -4/3
<h3>Factorization</h3>
Given the quadratic equation x^2 – 3x – 4 = x^2 – 6x + 8
x^2 – 3x – 4 - x^2 + 6x - 8 = 0
-3x + 6x - 4 + 8 = 0
3x + 4 = 0
- Subtrcat 4 from both sides
3x + 4 - 4 = 0 - 4
3x = -4
3x/3 = -4/3
x = -4/3
Hence the value of x from the given equation is -4/3

Answer:
A. How can the equation be used in temperature conversion?
You take the conversion equation C = (5/9) (F - 32) and you replace the F by the value of Fahrenheit degrees... then solve the calculations to get the degrees in Celsius.
For example, if you have 80°F to convert in °C:
C = (5/9) (80 - 32) = (5/9) (48) = 26.66 °C
B. How can you use the graph to find the body temp in C?
Using the graph will give a very imprecise measure due the scale of the graph.
But you would have to find 98.6 on the axis of X (it represents the °F), then go upwards until you find the line....
Then report that position on the line on the Y-axis (representing the °C) to get your measure.
y = (3x)/2 + 2
Slope = 3/2
y-intercept = 2
The first point is y-intercept when x = 0 = (0,2). Now according to our slope we move 3 up (Why up? Because it's positive) and 2 right (Why right? Because it's positive).
When you move 3 up from (0,2), you get (0,5) and move 2 right which is (2,5).
Remember: slope = change in y / change in x
Points: (0,2) and (2,5)
The only way to do this is when there is a decimal.
