Answer:
x=0
Step-by-step explanation:
- 7(x + 4) - 4= - 32
Add 4 to each side
- 7(x + 4) - 4+4= - 32+4
- 7(x + 4) = - 28
Divide by -7
- 7(x + 4) /-7= - 28/-7
x+4 = 4
Subtract 4 from each side
x+4-4 = 4-4
x=0

Answer:
(820 ; 980)
Step-by-step explanation:
Given :
Sample size, n = 80
Number of bilingual from sample = 36
Sample proportion, phat = x / n = 36 / 80 = 0.45
Margin of Error = 4% = 0.04
Interval = sample proportion ± margin of error
0.45 ± 0.04
(0.41 ; 0.49)
(0.41 * 2000 ; 0.49 * 2000)
(820 ; 980)
a) f (2) = 1
b) 
c) 
<u>Step-by-step explanation:</u>
- Indicates that we have to find the inverse of the function
Given data:
--------> eq.1
---------> eq.2
To find 
Case a)
Now, substitute x = 2 in the equation 1 to find f (2)

Case b)
Now, substitute x = 1 in the equation 2 to find 

Case c)
In general,

Thereby,
