A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).y -(-8) = -6(x - 2)y -(-8)

= -6x + 12y -(-8) + 8 = -6x + 12 + 8y = -6x + 20. Explain why the work is not correct.

Alright so the answer is 8/-67+56+90= 300 so that’s why it is incorrect

Answer:

The student should have simplified the equation to have y + 8 on the left.

Then, the student should have subtracted 8 from both sides of the equation.

The value of b should be 4, not 20.

3.920 * (1.018)^x = 5.500<br><br>X=?​
Andrei [34K]

Answer:

19

Step-by-step explanation:

3.920(1.018)ˣ = 5.500

  • First we can divide both sides by 3.920 to get: (1.108)ˣ = 1.403
  • Then we can take the natural log of both sides to get: ln[(1.108)ˣ] = ln(1.403)
  • We can then use logarithmic rules to move the x exponent to the front: xln(1.108) = ln(1.403)
  • Then we can divide both sides by ln(1.108) to get: x=\frac{ln(1.403)}{ln(1.018)}
  • Then using a calculator we get x = 18.98 ≈19

These data represent the volumes in cubic yards of the largest dams in the united states and in South America. Construct a boxpl
Vsevolod [243]

Answer:

Check it below

Step-by-step explanation:

1) The Boxplot is a visual tool to easily find the quartiles of a Distribution. To construct a boxplot it's necessary to organize the data, find at least the upper (3rd Quartile) and lower quartile (1st Quartile), and register the maximum and the minimum value.

2) This graph confirms that the South American ones have much more water than the North American counterparts. Notice the Upper Quartile, (the top of the box) for the Southern ones, it's over 100,000 yrds³. And Compare to the Northern one.
