The last one is the only one that will work.
For the first one the y intercept is when x = 0. The point would be 0,4
The second one gives a point of (4,0)
The third one is nonsense. (4,4) is not on this line.
Answer:
l = 2.25 cm
Step-by-step explanation:
given l is inversely proportional to w² then the equation relating them is
l = 
← k is the constant of proportion
(i)
to find k use the condition w = 1.5 , l = 16 , then
16 = 
= 
( multiply both sides by 2.25 )
36 = k
l = 
← equation of proportion
(ii)
when w = 4 , then
l = 
= 
= 2.25 cm
1/2 is the simpliest form,divide everything by 2
It's the first step.4x-x-2+6=6x+16 ##substract 2 rather an add 2
Check it carefully next time.!!
a) second and last one : 32x - 24 and 8*4x - 8*3
b) first and third one : 22y and 7y + 15y
pls mark brainliest!!
