Use an equation to find the value of k so that the line passing through (−4,k) and (6,−7) has a slope of −1/5.
Virty [35]

Answer:

k = -5

Step-by-step explanation:

Hi there!

m=\displaystyle \frac{y_2-y_1}{x_2-x_1} where the two points are (x_1,y_1) and (x_2,y_2)

Plug in the given information:

\displaystyle -\frac{1}{5}= \displaystyle \frac{-7-k}{6-(-4)} \\\\\displaystyle -\frac{1}{5}= \displaystyle \frac{-7-k}{6+4} \\\\\displaystyle -\frac{1}{5}= \displaystyle \frac{-7-k}{10} \\\\\displaystyle -\frac{2}{10}= \displaystyle- \frac{-7-k}{10} \\\\-2=-7-k\\k=-5

I hope this helps!

suter [353]

The sum of the numbers is 7.69 * 10^6

<h3>How to evaluate the sum?</h3>

The expression is given as:

(1.54 times 10 superscript 6 baseline) (6.15 times 10 superscript 6 baseline)

Rewrite properly

(1.54 * 10^6) + (6.15 * 10^6)

Factor out 10^6

(1.54 + 6.15) * 10^6

Evaluate the sum

7.69 * 10^6

Hence, the sum of the numbers is 7.69 * 10^6
