Step-by-step explanation:
This is confusing, what does g(x) equal? There's a bunch of random numbers there. I'll just assume.
They stated that f(x) needs to exceed g(x), so make an inequality plugging in the values
You see, function f(x) needs to be higher than function g(x)
Subtract 7x from both sides to get:
Divide both sides by -4, when you divide by a negative number the signs switch so it is now less than.
x < -1.5
And obviously that's not an answer up there, so you made a mistake stating the values of the functions
Answer:
48 years.
Step-by-step explanation:
Consider the complete question is "The ratio of ages of kissi and esinam is 3:5 and that of esinam and lariba is 3:5. The sum of ages of all 3 is 147 years. whats the age difference between oldest and youngest ?"
It is given that
Kissi : Esinam = 3:5 = 9:15
Esinam : Lariba = 3:5 = 15:25
So, the combined ratio is Kissi : Esinam : Lariba = 9:15:25
Let ages of Kissi, Esinam, Lariba are 9x, 15x and 25x.
Sum of ages of all 3 is 147 years.
The value of x is 3. So, the age of all three are
Since Lariba is oldest and Kissi is youngest, therefore, the difference between their ages is
Hence, difference between oldest and youngest is 48 years.
