Answer:
y = 3 + 1.5x
Step-by-step explanation:
4y = 12 + 6x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Divide each side by '4'.
y = 3 + 1.5x
Simplifying
y = 3 + 1.5x
Using a linear function, it is found that it will take 13 hours for the candle to burn down to a height of .25 inches.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
Considering the situation described, the y-intercept is of 10 while the slope is of -0.75, hence the height of the candle after t hours is given by:
h(t) = 10 - 0.75t
The height will be of 0.25 inches when h(t) = 0.25, hence:
0.25 = 10 - 0.75t
0.75t = 9.75
t = 9.75/0.75
t = 13 hours.

Answer:
X is equal to 7
Step-by-step explanation:
Open parenthesis.
3/4x +63/4=21/2
take common denominator
3/4x=42/4-63/4
Solve
3/4x=-21/4
3x=21
x=7
