Let's denote Cindy's age which is unknown with X
We know that Cindy's age is 3 times her age 6 years ago.
6 years ago Cindy's age was the present age (X) - 6 : X-6
The fact that the present age is 3 times her age 6 year ago can be written as:
3*(X-6)
So, finally:
X=3*(X-6)
Answer:
x= -1/2
Step-by-step explanation:
1. Create an equation
8x+4=0
2. Subtract 4 from both sides of the equal sign
8x = -4
3. Divide 8 from both sides of the equal sign to get x by itself
x= -4/8
4. Simplify
x= -1/2
function notation is the way a function is written. It is meant to be a precise way of giving information about the function without a rather lengthy written explanation.
A ball is thrown from an initial height of 2 meters with an initial upward velocity of 9/ms
Balls height
To find all values of t for which the ball's height is 3 meters
We plug in 3 for h and solve for t
Solve for t
Solve using quadratic formula
After simplifying this,
= 0.11898
= 1.68102
the values of t for which the ball's height is 3 meters= 0.12 sec , 1.68 sec
So if you do 3/5 it ends up equaling .6 you can convert that into a percent and it equals 60%
