No yes yes yes no ; sol. when x=4 , f(x) = 0 ,so (x-4) is right answer.....
The answer is = (3-2)x4 = (3-2)=1, 1x4=4
Answer:
x = 7
S.A.S
Step-by-step explanation:
2x + 14 = 4x
2x = 14
x = 7
Answer:
7/20
Step-by-step explanation:

Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.

...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get



Putting k=3.5 in (i), we get

This is the equation of proportionality.
Putting t=0.8, we get


Therefore, the value of s is 4.375 when t=0.8.
