a number is raised to a negative exponent is negative?
A always
B never
C sometimes
9 simplify(4xy^2)^3(xy)^5
A 64x^8 y^11
B 64x^15 y^30
C 12x^2 y^11
D 12x^8 y^11
10 simplify(2t^-3)^3(0.4r)^2
a 3.2r^2
b 1.28r^2/ t^-6
c 1.28r^2/ t^9
d 0.8r^2/ t^-6

step-by-step explanation:

use context clues to figure out the meaning of the bolded word:  

the sage gardener knew when she had to water her plants.  

question 8 options:

mint plant

wise

happy

lazy

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

are ya tryin to ask something or is this a statement
