1.8×10^-2 = 0.018

3.9×10^-3 = 0.0039

So

1.8×10^-2-3.9×10^-3

= 0.018 - 0.0039

= -0.0141

<span>Answer in scientific form notation:</span>

<span>= -1.41 *10^-2</span>

Which equation represents a line that has a slope of 1/3 and passes through point (-2, 1)?
Lorico [155]

Considering the definition of a line, the equation of the line that passes through the point (-2, 1) and has a slope of 1/3 is y= 1/3x + 5/3.

<h3>Linear equation</h3>

A linear equation o line can be expressed in the form y = mx + b

where

  • x and y are coordinates of a point.
  • m is the slope.
  • b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.

<h3>Line in this case</h3>

In this case, you know:

  • The line has a slope of 1/3.
  • The line passes through the point (-2, 1).

Substituting the value of the slope m, you get:

<u><em>y= 1/3x + b</em></u>

Replacing the value of the point in previous expression, the value of the ordinate to the origin b can be obtained:

1= 1/3× (-2) + b

1= - 2/3 + b

1 + 2/3= b

<u><em>5/3= b</em></u>

Finally, the equation of the line is y= 1/3x + 5/3.

If anyone can help me it would be appreciated I will give out 50 points I need answers quick.
Allushta [10]

Answer:

Step 4

Step-by-step explanation:

Tasha was correct in all the steps leading up to the fourth one. However, in the fourth step was where she messed up.

She said that: \frac{1}{256} =-\frac{1}{4^{-4}}=4^{-4}

However, when we have a negative exponent, in order to get rid of the negative, we simply take the reciprocal of the number and then make the exponent positive. Here, the answer should be:

\frac{1}{256} =\frac{1}{4^{4}}=4^{-4}
