Step-by-step explanation:
The two thermometers developed by cindy Grade and Gabriel Fahrenheit are shown in the attached photo
Let x = a certain temperature reading on the Gabriel Fahrenheit's thermometer
Let y = a corresponding temperature reading on the cindy Grade's thermometer
Interpolating the temperatures, it becomes
(212 - 32)/(212 - x) = (150 - 0)/(150 - y)
(212 - 32)(150 - y) = 150(212 - x)
180(150 - y) = 31800 - 150x
2700 - 180y = 31800 - 150x
180y - 150x = 31800 - 27000
180y - 150x = 31800 - 27000
180y - 150x = 4800
The scales will agree at a common reading. This is achieved by making x to equal y. Therefore
180x - 150x = 4800
30x = 4800
x = 4800/30 = 160
At a reading of 160, both scales will agree
This expression is easily factored: <span>x^2-4x+3 = (x-3)(x-1).
Setting these factors = to 0, we get x = 3 and x = 1. These are the desired rational roots.

The answer to this question is A, the graphs y intercept is 5
Answer: 15
Step-by-step explanation:
You have to multiply what Jackson made last year (24 cups) times 10 which equals 240. after that you do 240 divided by 4, which equals 60, and 60 divided by 4 again, which gives us the answer (15) (hope you could understand that) Also sorry for not answering in time!
