b- 7 and 10
Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the line parallel to 3x - y = 14 we must first find the slope of 3x - y = 14.
So we have
y = 3x - 14
Comparing with the general equation above
Slope / m = 3
Since the lines are parallel their slope are also the same
So slope of parallel line = 3
Equation of the line using point ( - 4 , -7) and slope 3 is
<h3>

We have the final answer as

Answer:
9 (5e - 3f)
Step-by-step explanation:
45e -27f
45e = 9*5*e
27f = 9*3*f
The common factor is 9
9*5*e - 9*3*f
9 (5e - 3f)
.25 Is the answer If that helps you enough
