What is the value of k?
Romashka-Z-Leto [24]

Answer:

k = 10

Step-by-step explanation:

The triangles angels added up must equal 180 degrees, and the top angle is 65 degrees by the 180 degree rule.  

So 10k + 15 must equal the remaining 115

subtract 15 from each side and you get 10k = 100

divide each each by 10 and you get the answer of k = 10

Find the slope for (-5,4)(-6,-2)
prohojiy [21]
6

Slope is change in y over change in x. -2-4 is -6, and -6- -5 which is -6+5 is -1. -6 over -1 is positive 6, so the slope is 6.

Determine which lines, if any, are parallel or perpendicular. Explain.
Orlov [11]

Answer:

line a and b are parallel, there is no perpendicular lines

Step-by-step explanation:

Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.

When the slopes are the same, they are parallel.

When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex. \frac{a}{b} and -\frac{b}{a} are perpendicular slopes.

Finding slope is using the formula: \frac{y_{2}-y_{1}  }{x_{2} -x_{1} }

Line a has slope  \frac{3-4}{4-0} = -\frac{1}{4}

Line b also has slope -\frac{1}{4}

Line c has slope 2

Since slope of line a and b are same, they are parallel.

Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.

How is rate of change of a linear function related to the slope of its graph
Neporo4naja [7]
The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . ... If coordinates of any two points of a line are given, then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.Apr 15, 2018
