Find the value of x. log 2 x = 3 A. 5 B. 6 C. 8 D. 9

Nataly_w [17]

Answer: Option C

$x =8$

Step-by-step explanation:

To solve this problem use the properties of the logarithms.

We know that the inverse function of $y = log_2 (x)$ is $y = 2 ^ x$ .

So when composing the function with its inverse function we have to:

$2 ^ {log_2 (x)} = x$ .

Now apply this property on both sides of the equation

$log_2(x) = 3\\\\2^{log_2(x)}=2^3\\\\x = 2^3\\\\x = 8$

the answer is the option C

Find an equation for the line that passes through the points (-5, -5) and (3, 5)

Luda [366]

Answer:

5x-4y+5=0.

Step-by-step explanation:

1) if the point A(-5;-5) and B(3;5), the formula is:

$\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A}$

2) according to the formula above:
$\frac{x+5}{3+5} =\frac{y+5}{5+5}; \ = > \ \frac{x+5}{4}=\frac{y+5}{5};$

or 5x-4y+5=0.
