We are given equations y =3.5x and y=25x +40.50.
Where x represent time in hours and y represents cost in dollars.
We need to determine that which equation is not the equation of a proportional relationship?
In first equation we have slope 3.5 and y-intercept 0.
In second equation, we have slope 25 and y-intercept 40.50.
<em>In order to have a a proportional relationship, there should be y-intercept =0.</em>
<h3>Therefore, y= 25x + 40.50 is not the equation of a proportional relationship.</h3>
Answer:
C) In step 3, he should have determined which square is closest to 18.
Step-by-step explanation:
17.64 also rounds to 18. 17.64 differs from 18 by ...
18 -17.64 = 0.36
whereas 18.49 differs from 18 by ...
18.49 -18 = 0.49
Hence 17.64 is closer to 18 and we might expect 4.2 to be closer to √18 than is 4.3.
___
The actual root of 18 is about 4.243, so 4.2 is a better approximation.
Answer:
The answer to your question is 2 or (2, 0)
Step-by-step explanation:
Data
slope = m = 4
y-intercept = -8
Process
1.- Write the equation of the line in the slope y-intercept
y = mx + b
In this equation:
m = slope
b = y-intercept
-Substitution
y = 4x - 8
2.- To find the x-intercept, consider that y = 0 and solve for x.
0 = 4x - 8
4x = 8
x = 8/4
x = 2 or (2, 0)
When he cubed ,
Result is x³
On further squaring x³, he got = (x³)²
<h3>Therefore, k =
6</h3>
