Answer:
4.13 m
Step-by-step explanation:
using Pythagoras theorem
The negative number would most likely be -19/2
let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0
hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2
A given score in a given percentile means that percentage of scores was below the given score. The appropriate choice is ...

Answer:
C) 12
Step-by-step explanation:
These type of questions is basically asking you to replace x with 2. f(x) is the same thing as y = but inside the f(x) is the value of x. So in this case, the numerical value of x is 2. All we need to do is replace x with it's numerical value, 2, and solve the equation.
