<h3>Answer: positive</h3>

We're adding a negative to a positive. The sign of number that is larger in magnitude will determine the sign of the answer.

The 4.3 is negative while the 14.5 is positive. The 14.5 is larger than 4.3, so the sign of 14.5 will be the sign of the answer. This is why the final answer is positive.

You can think of  (-4.3) + 14.5 as 14.5 + (-4.3) = 14.5 - 4.3 if it helps you see why the answer is positive.

Which equation represents the line that passes through (-6, 7) and (-3, 6)?
Degger [83]

For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

y = mx + b

Where:

m: It is the slope of the line

b: It is the cut-off point with the y axis

We have the following points through which the line passes:

(x_ {1}, y_ {1}): (- 6,7)\\(x_ {2}, y_ {2}): (- 3,6)

We find the slope of the line:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {6-7} {- 3 - (- 6)} = \frac {-1} {-3 + 6} = \frac {-1} {3} = -\frac {1} {3}

Thus, the equation of the line is of the form:

y = - \frac {1} {3} x + b

We substitute one of the points and find b:

6 = - \frac {1} {3} (- 3) + b\\6 = 1 + b\\b = 5

Finally, the equation is:

y = - \frac {1} {3} x + 5

Answer:

y = - \frac {1} {3} x + 5

Use index form. N= a^x becomes log a (N) = x
Therefore your question becomes (log 2.3 (13))/9 = x
And rounding to 3 decimals gives you 0.342
