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 $k=\frac{-1}{17}$

Does anyone know how to do this ?

dedylja [7]

Answer:

w=3 h=4

Step-by-step explanation:

14=2w+2h w=(3/4)h

substitute

14=2(3/4)h+2h

distribute

14=1.5h+2h

simplify

14=3.5h

divide both sides by 3.5

4=h

plug into original equation

w=(3/4)4

w=3

Which expressions are equivalent to 7 (negative three-fourths x minus 3)? Select two options.

polet [3.4K]

The equivalent expressions are:

$7(-\frac{3}{4}x - 3) = (7 \times \frac{-3}{4}x) + (7 \times -3)\\\\7(-\frac{3}{4}x - 3) = \frac{-21x}{4} - 21$

Solution:

Given expression is:

$7(-\frac{3}{4}x - 3)$

We have to find the equivalent expressions

By distributive property,

a(b + c) = ab + ac

Therefore,

$7(-\frac{3}{4}x - 3) = (7 \times \frac{-3}{4}x) + (7 \times -3)\\\\7(-\frac{3}{4}x - 3) = \frac{-21x}{4} - 21$

Thus equivalent expressions are found
