Answer:
x=10
Step-by-step explanation:
We can use the angle bisector theorem to solve this problem
8 12
-------- = ---------
x+4 2x+1
Using cross products
8(2x+1) = 12(x+4)
Distribute
16x+8 = 12x+48
Subtract 12x from each side
16x -12x +8 = 12x-12x +48
4x +8 = 48
Subtract 8 from each side
4x+8-8 = 48-8
4x = 40
4x/4 = 40/4
x=10
Step-by-step explanation:
Given the information above, we can simply set up an equation so we can find the value of x.
Subtract 42 on both sides.
Divide 14 on both sides.
So, the value of x is equal to -1/2 when f(x) is 35.
Use a/ 1-r
Where a = 18 and r = 1.2
18/ 1 - 1.2 = 18/-.2 = -90
Because the answer is below 1. The sum does not exist therefore it diverges.
Between 10 and 11, all the others would be to much or to little
Answer:
2 additional premium channels
Step-by-step explanation:
Using the given function, we substitute c(x) = 114 and solve for x:
114 =90 + 12x
Subtract 90 from both sides:
24=12x
Divide both sides by 12:
2=x
So you have ordered 2 additional premium channels.
