3 0

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

Answer:

C. x = 3

Step-by-step explanation:

When x = 3:

f(x) = x - 3 = 3 - 3 = 0

g(x) = e^{x-3} - 1 = e^{3-3} - 1 = e^{0} - 1 = 1 - 1 = 0

0 = 0

Anit [1.1K]

For this case we have to by definition, if "y" varies directly with "x" then it is true that:

y = kx

Where:

k: Is the constant of proportionality

We find the constant "k" according to the given data:

14 = k (-4)\\k = - \frac {14} {4} = -\frac {7} {2}

Thus, the constant of proportionality is - \frac {7} {2}.

Now, we find the value of "y" when x = -6:

y = - \frac {7} {2} (- 6)\\y = \frac {42} {2}\\y = 21

Thus, whenx = -6, the value of y is 21.

ANswer:

y = 21
