Solve log2(3x) + log2 (4) = 4

a.) x=4/3
b.) x=3/4
c.) x=4
d.) x=6

Step-by-step explanation:

log2(3x) + log2(4) = 4

log2(3x × 4) = 4

log2(12x) = 4

12x = 2⁴

12x = 16

x = 16/12

= 4/3

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
