Answer:
x-intercept is (2,0) [The x-intercept means that it takes 2 hours for the temperature to reach 0°C]
y-intercept is (0, -6) [The y-intercept represents the temperature at sunrise, -6°C]
Step-by-step explanation:
<u>Complete Question:</u>
<em>The air temperature is -6 degrees celcius at sunrise and rises 3 degree celcius every hour for several hours. The air temperature after x hours is represented by the function f(x) = 3x - 6. Find the x-intercept and y-intercept and interpret their meaning.</em>

- The x-intercept is the x-axis cutting point found by setting y = 0 [function = 0]
- The y-intercept is the y-axis cutting point found by setting x = 0
Lets find x-intercept first:
f(x) = 3x - 6
0 = 3x - 6
3x = 6
x = 6/3
x = 2
x-intercept is (2,0)
Now, lets find y-intercept:
f(x) = 3x - 6
f(x) = 3(0) - 6
f(x) = -6
y-intercept is (0, -6)
The x-intercept means that it takes 2 hours for the temperature to reach 0°C
The y-intercept represents the temperature at sunrise, -6°C
Answer:
2x10^6 = 2 Million gallons of water.
8.7 days = 209 hours
209 x 2,000,000/24 = 17,416,666.6667 Gallons of Water in 8.7 days
Step-by-step explanation:
Answer:
D.) 2+y+z=9
Y+z=9-2=7
-2x-4y-z=3
-2x/-2- - 4y/-2- z/2=3/2
X-z/y=3/2 z=1 y=1 x = 3.5
Answer: The y-intercept is (0, -12)
Step-by-step explanation:
y = 40x - 12
y = 40(0) - 12
y = -12
