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.
Answer:
y = -1/3x -3
Step-by-step explanation:
-2x - 6y = 18
We want to solve for y since the slope intercept form is y =mx+b where m is the slope and b is the y intercept
Add 2x to each side
-2x-6y +2x = 2x+18
-6y = 2x+18
Divide each side by -6
-6y/-6 = 2x/-6 + 18/-6
y = -1/3x -3
This is in slope intercept form with the slope -1/3 and the y intercept -3

Answer:
40
Step-by-step explanation:
Put 4 where x is and evaluate.
... f(4) = 3·4² -2·4
... f(4) = 3·16 - 8
... f(4) = 48 - 8 = 40
Answer:
x=8 and the base is 4 units long.
Step-by-step explanation:
We know the 2 sides are = so
2x-1 = x+7
Subtract x from both sides
x-1=7
Add 2 to both sides
x=8
We now know that x=8. The base is labeled x-4.
8-4=4 so the base is 4 units long.
