What I'm getting out of it is that you want to know how much he spent in all and if you mean that he spent $95.37 in all.
I hope I helped :)
Answer:
D = {-2, 0}
Step-by-step explanation:
If the range is {-3, 1}, that means -3 and 1 are <em>images</em> of some points a, b in the domain. So, there are two points a, b in the domain such that:
g(a) = -3 and g(b) = 1
If g(a) = -3 then 2a + 1 = -3 ------>2a = -4 ------> a = -2
If g(b) = 1 then 2b + 1 = 1 ------> 2b = 0 ------> b = 0
Hence D = {-2, 0}
Answer:
107°
Step-by-step explanation:
m∠m+m∠p= 180°
(7x+31)°(21x-19)°=180°
7x+31+21x-19= 180
7x+21x=180+19-31
28x=168
x= 168/28
x= 6
m∠p= (21x-19)°
= (21(16)-19)°=(126-19)°
= 107°
