Answer:
there is your answer
Step-by-step explanation:
270=2b + a
420=2a + 3c (you have to use trial and error for this)
B = 120
A = 30
C = 120
Just to check
270 = (2x120) + 30
420 = (2x30) + (3x120)
Well, the slope of this equation is 3 and the y intercept is -4.

Answer:
769MIN
Step-by-step explanation:
Hello!
To solve this problem we must use the straight line equation, this equation is as follows
Y=mx+b
where
X= time
Y=Temperature
b=
intercept with the y axis when x = 0, therefore y = 400
m=k=
temperature decrease with respect to time=-0.325
now we replace the values in the equation of the line
Y=-0.325X+400
Now we find the time it takes for the pizza to reach 150 F replacing in the equation and finding X
150=-0.325X+400
150-400=-0.325X+
