Answer:
x=180°
Step-by-step explanation:
![cos x+1=0\\cos x=-1=-cos0=cos(\pi -0)=cos \pi \\x=\pi =180^\circ](https://tex.z-dn.net/?f=cos%20x%2B1%3D0%5C%5Ccos%20x%3D-1%3D-cos0%3Dcos%28%5Cpi%20-0%29%3Dcos%20%5Cpi%20%5C%5Cx%3D%5Cpi%20%3D180%5E%5Ccirc)
The other side would have a length of 5m
AB was 3 and then became 6, it appears that it doubled <span>so the dilation factor is 3</span>
(7,2)
There you go, that's the answer.
Answer: y=1/4x+5
Step-by-step explanation:
Slope intercept form is
y=mx+b
where mx is the slope and b is the y-intercept.
The y-intercept is the part were the line touches the y axis, which in this case you can see is the five
To find the slope you need to use two points. I used (0,5) and (4,6).
This part is kind of tricky to explain so I kinda hope you already know this and sorry if it doesnt make sense but the slope needs to be written as rise/run which could also be reffered to as difference in y/difference in x. So basically what I did is subtract the difference in y values, which is 1 and the difference in x values, which is 4. And then I just put the difference in y value over the difference in x value
(ps I'm really sorry if im wrong-)
