I think that i got it but at the same time not sure but the value of a+b should be 14+20
X + 2/3 = 2x - 4/2
2/3 + 4/2 = 2x - x
2 + 2/3 = x
8/3 = x
I hope this helps!
The object should be placed 20/cm from the lens so as to form its real image on the screen
<h3>Mirror equation</h3>
The mirror equation is given according to the expression below;
1/f = 1/u + 1/v
where
f is the focal length
u is the object distance
v is the image distance
Given the following parameters
f = 5cm
v = 20cm
Required
object distance u
Substitute
1/5 = 1/u +1/20
1/u = 1/5-1/20
1/u = 3/20
u = 20/3 cm
Hence the object should be placed 20/cm from the lens so as to form its real image on the screen

Answer:
M=-10
Step-by-step explanation:
To find the sope we use y-y1/x-x1. For this problem, I chose the first two coordinates.
(-33.5)-(-55.6)/1.20-3.45=22.6/-2.25=-10(rounded)
hope this helps!:)
