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
Answer:
X=8
Step-by-step explanation:
Cross multiply:
4 * 6 = x * 3
Simplifying
4 * 6 = x * 3
Multiply 4 * 6
24 = x * 3
Reorder the terms for easier multiplication:
24 = 3x
Solving
24 = 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
24 + -3x = 3x + -3x
Combine like terms: 3x + -3x = 0
24 + -3x = 0
Add '-24' to each side of the equation.
24 + -24 + -3x = 0 + -24
Combine like terms: 24 + -24 = 0
0 + -3x = 0 + -24
-3x = 0 + -24
Combine like terms: 0 + -24 = -24
-3x = -24
Divide each side by '-3'.
x = 8
Simplifying
x = 8
