Use an equation to find the value of k

Delvig [45]

$\boxed{k=4}$

<h2>Explanation:</h2>

We know that the slope of a line is given by:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} \\ \\ Where: \\ \\ (x_{1},y_{1}) \ and \ (x_{2},y_{2}) \ are \ points \ that \ lie \ on \ the \ line \\ \\ \\ Here: \\ \\ (x_{1},y_{1})=(-2,k) \\ \\ (x_{2},y_{2})=(2,0) \\ \\ m=-1 \\ \\ \\ -1=\frac{0-k}{2-(-2)} \\ \\ -1=\frac{-k}{4} \\ \\ -k=4(-1) \\ \\ \boxed{k=4}$

Two angles are complementary. One has a measure of 25 degrees. What is the measure of the other angle?

Pani-rosa [81]

Answer:

65 degrees

Step-by-step explanation:

Since complementary angles are 2 angles that add up to 90 degrees, all you have to do is subtract 25 from 90.

When you do that you get 65.

Example: 90 - 25 = 65

Answer:

x = 19, y = -5

Step-by-step explanation:

x + y = 14 => x= 14-y

2x + 4y = 18 => 2(x+2y)=18 => x+2y=9

x+2y=9 => (14 - y) + 2y = 9

14 + y = 9 => y = -5

x + (-5) = 14 => x=19
