A is more likely. Heating something to fast and for too long can cause stress on the glass causing it to crack. Water wouldn’t have effected it
Using a linear function, we have that:
a) The fixed cost is of $10.
b) The equation is: C = 10 + 12d.
c) The cost of an 18 km trip is $226.
d) The distance traveled is of 20 km.
<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.
For this problem, the slope is of m = 12. When d = 5, C(d) = 70, hence we find the fixed cost as follows:
C(d) = 12d + b
70 = 60 + b
b = 10.
Hence the equation is:
C(d) = 12d + 10.
For a trip of 18 km, d = 18, hence the cost is:
C(12) = 12 x 18 + 10 = $226.
When the cost is of $250, the distance is found as follows:
250 = 12d + 10
12d = 240
d = 240/12
d = 20 km.

#SPJ1
Answer:
x=1 y=3
Step-by-step explanation:
3x+y=6 is the same as y=6-3x
2x-y=-1 is the same as y=2x+1
set them equal to each other
6-3x=2x+1
5x=5
x=1
substitute the value of x into either equation
y=2(1) +1
y=3
