106. d: Given the equation
5(-3x - 2) - (x - 3) = -4(4x + 5) + 13
Multiply factors.
-15x - 10 - x + 3 = -16x - 20 +13
Group like terms.
-16x - 7 = -16x - 7
Add 16x + 7 to both sides and write the equation as follows
0 = 0
The above statement is true for all values of x and therefore all real numbers
are solutions to the given equation.
107. c: Given the algebraic expression
2(a -3) + 4b - 2(a -b -3) + 5
Multiply factors.
= 2a - 6 + 4b -2a + 2b + 6 + 5
Group like terms.
= 6b + 5
108. a: Given the expression
|x - 2| - 4|-6|
If x < ;2 then x - 2 < 2 and if x - 2 < 2 the |x - 2| = -(x - 2).
Substitute |x - 2| by -(x - 2) and |-6| by 6 .
|x - 2| - 4|-6| = -(x - 2) -4(6) = -x -22
109. d: The distance d between points (-4 , -5) and (-1 , -1) is given by
d = sqrt[ (-1 - -4) 2 + (-1 - -5) 2 ]
Simplify.
d = sqrt(9 + 16) = 5
110. c: We first calculate the slope m
m = (1 - 3) / (4 - 2) = -1
We now use the point-slope form of a line to find the equation of the line
y - y1 = m(x - x1) , where m is the slope and (x1,y1) is any of the two points given
above.
Substitute m by its value -1 and x1 and y1 by 2 and 3 respectively, we obtain
the equation of the line.
y - 3 = -1(x - 2)
in slope intercept form the equation is written as
y = -x + 5
111. b:
There will be a 50% chance (2 out of 4) of having a carrier (Aa) child. Similarly, each time there will be a 25% chance of having an offspring who will inherit the disease (aa) and die.
