So, you start by separating the equation into two inequalities and you get
4x+1 > -7 and 4x +1 < 5
Solve these inequalities and you get your final answer:
x > -2 and x < 1
(The equalities symbols are supposed to have the "or equal" line beneath them, I was just too lazy to put them.)
X/6 + 7 = 20
subtract 7 from each side
x/6 + 7 - 7 = 20 - 7
x/6 = 13
multiply each side by 6 to get x alone
x/6 • 6 = 13•6
x = 78
Answer:
sorry bout the second part I wrote mm instead of m. Besides that I think this will be the correct answer. Hope this helps
Answer:
13
Step-by-step explanation:
We're trying to find the distance between points X and Y. Or the distance of X-Z plus Z-Y.
Lets find the distance of X-Z
6-2=4
Now lets find the distance of Z-Y
15-6=9
Now we add the distances
4+9=13
So you have to find the velocity (or first derivative) from the position function of h=-16t^2+48t+6
the velocity is -32t+48 which you then have to set equal to 0 in order to find t
-32t+48=0
-32t=-48
t=1.5
you then take your t value and sub it back into your original position function
-16(1.5)^2+48(1.5)+6 which will give you a maximum height of 42 feet
so the time it takes is 1.5 seconds to reach a maximum height of 42 feet
