Answer:
sin x = -0.8
x = -53.13010235 (used inverse of sin)
tan 2x
tan -106.2602047
= 0.61854704132
Answer:
(x ^ 16y ^ 22)
Step-by-step explanation:
For this case we have the following expression:
(x ^ 6y ^ 8) ^ 3 / x ^ 2y ^ 2
Rewriting and for power properties we have:
(x ^ 18y ^ 24) / x ^ 2y ^ 2
(x ^ (18-2) y ^ (24-2))
(x ^ 16y ^ 22)
-3x -8y = -23
4(7x + 2y = -13)
-3x -8y = -23
28x + 8y = -52
25x = -75
x = -3
-3(-3) - 8y = -23
9 - 8y =-23
32 = 8y
y=4
7(5 + m) - 8 is equivalent to 35 + 7m - 8.
7(5+m)-8, multiply 7 with 5 and m and you get 35 + 7m - 8 which is also equal to 27 - 7m.
//Hope this helps.
