Answer:
a) f(0) = -9
b) f(2) = -5
c) f(-3) = -15
d) f(1/2)=-8
Step-by-step explanation:
We are given the function 
and we need to find the following:
a) f(0)
For finding f(0) put x =0 in the given function
So, we get f(0)=-9
b) f(2)
For finding f(2) put x =2 in the given function
So, we get f(2)=-5
c) f(-3)
For finding f(-3) put x =-3 in the given function
So, we get f(-3)=-15
d) f(1/2)
For finding f(1/2) put x =1/2 in the given function
So, we get f(1/2)=-8

Answer:
x = 13
39° and 51°
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
This is a right angle triangle, so one side has a size of 90 degrees.
3x + 4x - 1 + 90 = 180
7x + 89 = 180
7x = 91
x = 91/7
x = 13
Put x as 13 to work out the size of the angles.
3(13) = 39
4(13) - 1
52 - 1 = 51
Answer:
A: x = 20
Step-by-step explanation:
Suppose that you use the health club x time
When you will use it charged will=12+9=21
Equating both side
300+6x=21x
300=15x
X=20 member
