<u>4x - x/4 + x + 1/3 = 2x</u>
Add up the 'x' terms on the left side: (4 + 1/4 + 1)x = 5-1/4 x = 21/4 x
Now the equation is: 21/4 x + 1/3 = 2x
2x is the same as 8/4 x . Subtract it from each side:
13/4x + 1/3 = 0
Subtract 1/3 from each side :
13/4 x = - 1/3
Multiply each side by 4 :
13 x = - 4/3
Divide each side by 13 :
<em>x =</em> (- 4/3) / (13) = <em>- 4 / 39</em>
Answer:
its the second one
Step-by-step explanation:
1. starting point of the domain ( x-axis ) is 0
2.ending is at 3
If x + y = 6, then solve for y to get: y = 6 - x.
Now replace y with 6 - x in both equations.
(5x)/3 + 6 - x = c
2(6 - x) = c - 4x
The upper equation is solved for c.
Now we solve the lower equation for c.
c = 2(6 - x) + 4x
c = 12 - 2x + 4x
c = 2x + 12
Since we have two equations solved for c, we substitute to get
(5x)/3 + 6 - x = 2x + 12
This is an equation in only x, so we can solve for x.
(5x)/3 - 3x = 6
5x - 9x = 18
-4x = 18
x = -9/2
Now we solve for y.
x + y = 6
-9/2 + y = 6
y = 9/2 + 12/2
y = 21/2
Now we solve for c.
c = (5x)/3 + y
c = (5 * (-9/2))/3 + 21/2
c = -45/6 + 21/2
c = -15/2 + 21/2
c = 6/2
c = 3
Answer: c = 3
the
complete question in the attached figure
part A
the x intercept 0 is the point where the ball was hit, the x intercept 20 is the point where the ball fell back to the ground, 20 feet away from the kicker.
<span>the function is increasing in the interval x∈(0, 10) and decreasing in x∈(10, 20) </span>
this means that the height is increasing in the interval (0, 10) and decreasing as x goes through the interval (10,20)
the distance from the kicker is increasing during the whole interval (0, 20)
part B
the rate of change represents the slope of the secant line from A to B. It approximates the rate at which f(x) decreases or increases in the interval
x =[A, B]
from x = 22 to x = 26-------------- > the function does not exist
Your answer is in the picture above
