The number line below represents the solution to which inequality? < --|--|--|--|--|--o--|--|--|--|--|-- |--|--|--|--> __ --2 __0 __2 __4 __6(filled circle)(arrow pointing left from -2)f. -2x + 7 > 8 _g. 7x + 11 < 4 _h. 6x - 9 < -21 _j. -3x -15 < -27 _

Step-by-step explanation:

We are given with a

FILLED CIRCLE : If circle is filled that means that that point is also included in the number line solution.

here we are given that the arrow is pointing left from -2 and the circle is filled

hence -2 is included and as the arrow is pointing towards left towards negative , the includes all the point less or equal to -2

The solution of the in equation would be

x ≤ -2

Unfortunately none of the option gives the above value of x.

He meant a filled circle.

Step-by-step explanation:

there are no answer choices

step-by-step explanation:

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
