Answer:
5,184
Step-by-step explanation:
multiply each unit by 6 and then you end up with 12, 24, and 18. Then you multiply all these answer by each other and get 5,184.
Here are the steps
put it into y=mx+b 4y=-5x+20
to isolate y divide both sides by y=-5/4+5
to find the xi
xi is when y=0 so plug it in to the equation 4y=-5x+20 4(0)=-5x+20
0=-5x+20 subtract 20 from each side -20=-5x the negatives cancel out 20=5x
to isolate x divide each side by 5 x=20/5
20/5=4
Answers:
m=-5/4
yi=5
xi=4
Answer:



Step-by-step explanation:
Given



(0, 1, 0)
The vector equation is given as:

Substitute values for x, y and z

Differentiate:

The parametric value that corresponds to (0, 1, 0) is:

Substitute 0 for t in r'(t)




The tangent line passes through (0, 1, 0) and the tangent line is parallel to r'(0)
It should be noted that:
The equation of a line through position vector a and parallel to vector v is given as:

Such that:
and 
The equation becomes:




By comparison:
and 
The parametric equations for the tangent line are:

In english, what this is saying is that for every 5 units of weight on Earth, is 7 units of weight on Neptune.
Given this, it would make sense that your weight on Neptune, say Y, equals your weight on Earth, say X, divided by five, then multiplied by seven.
Y = (X/5) * 7
Y = (150/5) * 7 = 210
