3 0

If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:

y = x + 14
y = 3x + 2
______________
y = y
x + 14 = 3x + 2
14 - 2 = 3x - x
2x = 12
x = 6

y = x + 14 = 6 + 14 = 20

The correct result would be (x, y) = (6, 20); because both lines pass through this point.

Answer:

50°

Step-by-step explanation:

angle 5 = angle 4 ( Alternative Interior Angles are equal )

But angle 3 & angle 4 are linear pairs. So,

angle 3 + angle 4 = 180°

=> angle 3 + angle 5 = 180° (angle 5 = angle 4)

=> angle 3 + 130° = 180°

=> angle 3 = 180° - 130° = 50°

Nesterboy [21]

I think you have to list all of the temperatures in order from least to greatest during the first week (-31, -29, -9, -8, 3, 4, 6) in which case the median would be -8.

I hope this helps you and if you know the answer is wrong please let me know in the comments and I will take another look at the question to see if I can figure out the correct answer.

Hatshy [7]

Answer:

z = 3

Step-by-step explanation:

Since the points are collinear then the slopes between the points are equal.

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$
