Answer:
y - w + x
Step-by-step explanation:
y = w + v - x
or y - w + x = w + v - x - w + x [adding x and subtracting w from both sides]
or y - w + x = v
Therefore, v = y - w + x
Answer:
3
Step-by-step explanation:
g(x) = f(x) + k, is true for all values of x.
At x = 0, f(x) = 2
At x = 0, g(x) = 5
Therefore, at x = 0
=> g(x) = f(x) + k
=> 5 = 2 + k
=> 3 = k
Since, the given relation is true for all real values of x, k is independent of x. Thus k = 3, for every value of x
Answer:
10/07/20. t(x)=3x;t(x)=24
Step-by-step explanation:
Step-by-step explanation:
divede both numbers by 9 and tou will get 1/3
So from 75 to 80 and 75 is 100%
80-75=5
5 is x% of 75
x%=percent markup
5=x% times 75
% means parts out of 100 so
x%=x/100
5=x/100 times 75
5=75x/100
75x/100=75/100 times x
75/100=3/4
5=3/4x
multiply both sides by 4/3
20/3=x
6.6666%
the percent mark up is 6.6666%
