Answer:
The top one is refraction
Refraction is the bending or change in angle of light
Hope this helps (sorry I don’t have the answer to the second question)
Answer:
Science Club- y=10x+20
Math Club- y=5x+50
They will be equal 6 weeks
Step-by-step explanation:
X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)
Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.
To find the week when they will be equal, we have to put both equations equal to each other.
10x+20=5x+50
Now we solve for x, or the number of weeks when the equations (and values) will be equal.
10x+20=5x+50
5x+20=50
5x=30
x=6
So... 6 weeks :)
You can use desmos to graph if you need it.
X=9 is the answer. Hope this helps!!!
Answer:
y = 2x- 3
Step-by-step explanation:
1) D // D' , this means that mD = mD'
6x -3y +18 =0
6x +18 =3y
6x/3 +18/3 = y
2x +6 = y. m= 2
2) Find the equation of D'
y - y' = m (x - x')
y - 1 = 2(x - 2)
y-1 = 2x - 4
y = 2x-3
