27- Choice D is correct

The correct answer is:
M = 3 +
A =  J   5

28- Choice D is correct

The correct answer is 2
METHOD ONE:
log2(x + 6)  log2(x  2)=1
Add log2(x  2) to both sides:
log2(x + 6)  log2(x  2)+log2(x  2)=1+log2(x  2)
And simplify:
log2(x + 6)=1+log2(x  2)
Logarithm rule: a = logbba  1 =log221 = log22
then: log2(x + 6)=log22 + log2(x  2)
Logarithm rule: logca+logcb=logca b
then: log22 + log2(x  2) = log22 (x  2)log2(x + 6) = log22 (x  2)
When the logs have the same base: logb(f(x)) = logb(g(x))  f(x) = g(x)
x + 6 = 2 (x  2)  x + 6 = 2 x  4   x =  10  x = 10
METHOD TWO
We know that: logab  logac = logabc and logab = c  b = ac
Then: log2(x + 6)  log2(x  2)=log2x + 6x  2 = 1
x + 6x  2=21=2x + 6 = 2 (x  2)
 x + 6=2 x  42 x  x = 6 + 4  x = 10

 

29- Choice B is correct

The correct answer is 21
C94 = 9!4!(9  3)! = 9!4! 6! = 9 × 8 × 7 × 6!4! × 6! = 9 × 8 × 74 × 3 × 2 × 1 = 21

30- Choice D is correct

The correct answer is x  6
The number under the square root symbol must be zero or greater than zero therefore: 
x  6  0  x  6 domain of function = [6, + )

31- Choice B is correct

The correct answer is (2,2)
{12 x + 4 y=326 x  2 y=8 Multiplication ( 2) in first equation {12 x + 4 y=32 12 x + 4 y= 16
Add two equations together  8 y=16  y=2 then: x=2

32- Choice C is correct

The correct answer is 74
f(x)=4 x  12
y=4 x  12 
2 y = 4 x  1 
2 y + 1 = 4 x 
2 y + 14 = x
f  1=2 y + 14 
f  1(3) = 74

33- Choice A is correct

The correct answer is  x2  6 x + 4
(g + f)(x) = g(x) + f(x) = ( x2  3  5 x) + (7  x)
 x2 + 4  5 x  x =  x2  6 x + 4

34- Choice D is correct

The correct answer is (4, 7), 3 2
(x  h)2 + (y  k)2 = r2  
center: (h,k) and radius:r
(x  4)2 + (y + 7)2 = 18 
center: (4, 7) and radius: 3 2

35- Choice A is correct

The correct answer is 4 x + y = 4
If two lines are parallel with each other, then the slope of the two lines is the same.
Then in line y = 4 x , the slope is equal to 4
And in the line 4 x + y = 4 y = 4 x  4
the slope equal to 4

36- Choice C is correct

The correct answer is  30  x  18
| 6 + x |8  3  | 6 + x |  24 
 24  6 + x  24 
 24  6  x  24  6 
 30  x  18

37- Choice B is correct

The correct answer is 513 + i 1413
If z1 = x1 + i y1 and z2 = x2 + i y2 
z1z2 = x1 x2 + y1 y2x22 + y22 + i x2 y1  x1 y2x22 + y22
In this problem: x1 = 4, x2 =2, y1 = 1, y2 = 3
4 + i2  3 i = 513 + i 1413

38- Choice D is correct

The correct answer is 3
tan (π3) =3

39- Choice B is correct

The correct answer is 2 a2 3 a
48 a7 b22 a2 b2=4 a2 b32 a b = 2 a2 3 a

40- Choice B is correct

The correct answer is 4 (2 x + 1)
f(x)=x  48  y = x  48  8 y = x  4  8 y + 4 = x
f  1 = 8 x + 4 = 4 (2 x + 1)
