What ordered pairs(2,-9)and(3,-6) istrue for the equation 5x-y/3=13
a) 2,-9
b) 3, 6
c) neither is a solution
d). both are the solution

the answer is a. 2, -9. i just had this question

correct answer:

i^31 = -i

its 69.420

step-by-step explanation:

multiple all that

step-by-step explanation:

27×17

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
