Step-by-step explanation:
if b+c=0
b=-c
x^b=x^-c
so
1/[2(x^b)+1]
Answer:
12
Step-by-step explanation:
560-500=60
60/500*100=12
![6x + 10y \geqslant 1450](https://tex.z-dn.net/?f=6x%20%20%2B%2010y%20%5Cgeqslant%201450)
This basically says that the total money made from tickets will be gretarr than or equal to $1450.
All the angles must add to 180degrees in a triangle.
180 = 59 + 35 + x
180 = 94 + x
86 = x
Supplementary angles x and z add to 180
180 = x + z
180 = 86 + z
94 = z
Now the last triangle is with angles 11, z, and y
they must add to 180 so...
180 = 11 + z + y
180 = 11 + 94 + y
180 = 105 + y
75 = y
Hope this helps!
