If B is the midpoint of AC, and AC= 8x-20, find BC.

Semmy [17]

Answer:

BC = 4x-10

Step-by-step explanation:

$\because B$ is the midpoint of AC.

$\therefore BC = \frac{1}{2} AC$

$\therefore BC = \frac{1}{2} (8x-20)$

$\therefore BC = \frac{1}{2} \times 2(4x-10)$

$\huge \purple {\boxed {\therefore BC = 4x-10}}$

Solve: K= 2(11 - k) + 14

mote1985 [20]

k=2(11-k)+14
k=22-2k+14
2k+k=22+14
3k=36
k=36/3
k=12

Solve this equation for x. Round your answer to the nearest hundredth. 3 = In(x + 9)

Mrac [35]

Answer:

x ≈ 11.09

Step-by-step explanation:

Using the rule of logarithms

$log_{b}$ x = n ⇒ x = $b^{n}$

Given

ln(x + 9) = 3 , that is

$log_{e}$ (x + 9) = 3 , then

x + 9 = e³ ( subtract 9 from both sides )

x = e³ - 9 ≈ 11.09 ( to the nearest hundredth )
