Answer:
The statement is true.
Step-by-step explanation:
Given : Reflecting the graph of y = sin x across the y-axis is the same as reflecting it across the x-axis.
To find : Is this statement true or false?
Solution:
Rules of reflection :
Along across y-axis if we have a point
So, y=sinx
The reflection across y-axis→ .......[1]
Along across x-axis if we have a point
so, y=sinx
The reflection across x-axis → .....[2]
Hence, [1] and [2] both of them are equal
Therefore, the statement is true.
Speed = distance / time => time = distance / speed
speed = 3x10^8 x 60 = 180x10^8 m per minute
time = 1.5x10^11/180x10^8 = 150x10^9/180x10^8 = 5/6x10 = 8,3 minutes
Answer:
7
Step-by-step explanation:
hurry!
please use my image as a reference (figure not drawn to scale).
AB is a straight line and the angle of a straight line = 180°
so that means
, solve for
:
combine like-terms
![5x+x=180-6\\6x=174\\x=\frac{174}{6}](https://tex.z-dn.net/?f=5x%2Bx%3D180-6%5C%5C6x%3D174%5C%5Cx%3D%5Cfrac%7B174%7D%7B6%7D)

if you want to make sure of the answer, plug in
in the equation:
![5x+(6+x)=180\\5(29)+(6+29)=180\\145+35=180\\180=180](https://tex.z-dn.net/?f=5x%2B%286%2Bx%29%3D180%5C%5C5%2829%29%2B%286%2B29%29%3D180%5C%5C145%2B35%3D180%5C%5C180%3D180)
