Yes because if you plug in (-1,2) to each equation you get a true statement.
Step-by-step explanation:
the item angle on the left line is also 130 degrees, as these 2 equally long lines create a triangle with 2 equal sides.
the two internal angles are the complement from 130 to 180 degrees, as every straight line stands for 180 degrees.
so, 180-130 = 50 degrees.
=> both internal angles are 50 degrees.
that makes the angle at the bottom tip of the triangle the complement of both 50 degree angle to 180, because the sum of all angles in a triangle is always 180 degrees.
so, 180 - 50 - 50 = 80 degrees.
and the outside angles of that triangle tip angle are each half of the complement of these 80 degrees to 180 (resistive to the bottom horizontal line).
180 - 80 = 100
100/2 = 50
so, both outside bottom angles are again 50 degrees.

What is the mean,mode,median,and range of 5,5,5,6,6,6,7,7,7,7,7
g100num [7]
Answer:
median=6, range=2 mean=61 mode=7
the median is the middle which is 6
The range is the lowest-biggest number which would be 2
mean=average
mode is the one that appears most
Answer:
y = 5/4x - 3
Step-by-step explanation:
Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
First, isolate variable y on the left side of the equation.
- 4y = - 5x + 12
Now, divide both sides by - 4 to solve for y.
y = 5/4x - 3
