Answer:
X=1/6 Y=0
Step-by-step explanation:
If Y= 6x-1, substitute Y on the first equation
7x+3(6x-1)=7/6
7x+18x-3=7/6
25x=(7/6)+3
25x=25/6
x=1/6
Then substitute X on the second equation
Y=6(1/6)-1
Y=0
$110 - ($13 x 5) - $9 - $14 =
$110 - $65 - $9 - $14 =
$110 - $56 - $14 =
$110 - $42 =
$68.
Hope this helped!

Answer: 90 or 96
Step-by-step explanation: 90 divided by 6 is 15, 96 divided by 6 is 16. Both of them have 9 as one of the digits
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.
