4. y= x-5, domain = {positive numbers}6. y= 5/x, domain = {x:0.4 is less than or equal to, x, is less than or equal to, 10}8. y= -0.4x+5, domain = {x: -2 is less than or equal to, x, is less than or equal to, 6}12. y=-x^2+5.4x+1, domain = {positive numbers}Teacher assigned multiple questions from Paul a. Foersters algebra and trigonometry book, but also didnt go into detail on how to solve these

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

i do not know the answer

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
