Here in the given equation, 3x + 8 the term 8 represents the weight of the empty bucket.

Its given that the number of marbles is x, and the weight of each marble is same which is 3. So, total weight of marbles is 3x.

Now, if 3x + 8 is the weight of the bucket and marbles, then 8 represents the weight of the empty bucket.

What is the answer for this
KonstantinChe [14]

Answer:  y=\frac{1}{30}x+1

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

You need to find slope of the line with the formula:

m=\frac{y_2-y_1}{x_2-x_1}

Pick to  points of the given line. You can choose the point (60,3) and the point (30,2).

Then, substituting into the formula:

 m=\frac{2-3}{30-60}=\frac{1}{30}

You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:

b=1

Substituting the slope and the y-intercept found into  y=mx+b, you get the equation of this line:

 y=\frac{1}{30}x+1

Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.

Is what i did correct?
yaroslaw [1]
No, you should have reduced each base to...
3^(3*2x) = 3^(2*(x-3))
and then you can cancel each base
3*2x = 2*(x-3)
6x = 2x-6
4x= -6
x = -3/2
