Answer:
250 miles
Step-by-step explanation:
Your formula is d=r(t)
d=distance r=speed t=time
In this equation it is asking you how far will you travel if your speed is 50 miles per hour, and the time is 5 hours.
So, using the equation above insert the known numbers and it should look like this: d=50(5) ( distance is unknown / speed is 50 / time is 5 )
Now you can find the distance. All you do is multiply 50 times 5 which equals 250.
So the correct answer is C. 250 miles

Step-by-step explanation:
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>
<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
