Complete Question:
Convert 3x-y+2=0 in rectangle form to polar form
Answer:
r ( 3cosθ - sinθ) = -2
Step-by-step explanation:
The equation so given is already in rectangular form, the task is to convert it to polar form.
3x - y + 2 = 0
To transform an equation from the rectangular to the polar coordinate:
x = r cosθ
y = r sinθ
Substitute the representations for x and y into the given equation:
3(r cosθ) - (r sinθ) + 2 = 0
3rcosθ - rsinθ = -2
The polar representation of the equation then becomes:
r ( 3cosθ - sinθ) = -2
The temperature is 86°F when the temperature is 30°C.
Step-by-step explanation:
Formula for Celsius to Fahrenheit;
F = 
Where C stands for temperature in degrees Celsius.
Given,
Temperature in Celsius = 30 degrees
Temperature in Fahrenheit = 
Temperature in Fahrenheit = 
Temperature in Fahrenheit = 
The temperature is 86°F when the temperature is 30°C.

Answer: 98
Step-by-step explanation:
98 / (-7) = -14
The 3 would be the y, so it would be 4x-3y
