Your mistake was that you wrote 7x-5 and 9x-16 as 7x+5 and 9x+16. You have to add the expressions the way it is. It helps to put the parenthesis around it. So when you add (7x-5)+(9x-16)+(3x+11) you get 19x -10 =180. So 19x=190, so x=10.
Answer:
3/10
Step-by-step explanation:
Part I: 2/5 = 4/10
Part II: 3/4(2/5) = 6/20 or 3/10
Part III: 10/10 - (4/10 + 3/10) = 3/10
Answer: 50%
Step-by-step explanation: math
Answer:
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b
Step-by-step explanation:
The domain refers to values for which the expression is defined.
This implies that, the denominators are not equal to zero.
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b
F (x) = 4x ⇒ y = 4x
↓
x = 4y Divide by 4 on both sides
↓
x / 4 = y ⇒ Inverse function = x / 4
