A line that includes the points (k,7) and (0,8) has a slope of 1 7 . What is the value of k?
Shalnov [3]

value of k is k=\frac{-1}{17}

Step-by-step explanation:

We are given points (k,7) and (0,8) has a slope of 1 7 . What is the value of k?

The formula to find the slope given two points is:

Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

where x₁ = k, y₁=7, x₂=0, y₂=0

Putting values:

Slope=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\17=\frac{8-7}{0-k}\\17=\frac{1}{-k}\\Multiplying\,\,both\,\,sides\,\,by\,\,-k\\17*-k=1\\Divide\,\,by\,\,17\\-k=\frac{1}{17}\\ k=\frac{-1}{17}

So, value of k is k=\frac{-1}{17}

mina [271]

Answer:

105.876373581

Step-by-step explanation:

8.563 + 4.8292 = 13.3922

13.3922 × 9.183 = 122.9805726

122.9805726 ÷ 1.192 = 103.171621309

103.171621309 ÷ 1.192 = 86.5533735811

86.5533735811 + 19.323 = 105.876373581
