Answer:
Step-by-step explanation:
5 - (x + 5) > -2(x + 4)
5 - x - 5 > -2x - 8
-x > -2x - 8
-x + 2x > -8
x > -8
4 2/3 /2 /5
14/3 / 2/5 cross multiply
7/3 / 1/5 multiply 7 and 5 and 3 and 1
35/3 simplify
11 2/3
X=5
7(5)-8=35-8=27
3(5)+12=15+12=27
$570.60 because 90/100=.90 so multiply that with 634 with .90 you get 570.60
F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855
now we have
-2 times 20.0855=-40.1711
answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
