Answer:
the distance equation is
Step-by-step explanation:
Let's assume
time in hours as 't'
distance traveled as 'd' meters
We are given
Moves 2 meters every 3 hours
So, firstly we find speed
we know that
distance = (speed)*(time)
now, we can plug values
now, we can plug value
So, the distance equation is
Graph:
For number 6 its A. 4
For number 7 its B. -2/5
Let the number equal x:
4 times x = 4x then 3 subtracted from that is 4x-3
4x-3 = 17
Add 3 to both sides:
4x = 20
Divide both sides by 4:
x = 5
Answer: X = 5
Answer:
a = - 1.1
Step-by-step explanation:
The condition for a single variable function f(x) to be decreasing is f'(x) < 0.
f(x) = 4/x^2 - 6x + 9
Then, differentiating with respect to x on both sides we get,
f(x) = 4(-2)(1/x^3) - 6 < 0
-8/x^3 - 6 < 0
8/x^3 + 6 > 0
{Dividing both sides with - 1 and hence the inequality sign changes}
8/x^3 > -6
8 > - 6x³ {Multiplying both sides with x³}
6x³ > - 8 {Interchanging the sides}
x^3 > -8/6
⇒ x > - 1.1
So, a = - 1.1
