Answer:
C
Step-by-step explanation:
All others can be proved false.
Reflection about the y-axis is according to the rule
(x,y)->(-x,y)
Therefore F(x,y) -> F'(-x,y)
The distance between F' and F is (-x,y)-(x,y)=-2x, or the positive distance is 2x.
The absolute value expression for the given statement is |10|
<h3>What is absolute value?</h3>
The absolute value (or modulus) | x | of a real number x is the non-negative value of x without regard to its sign
Marcus was going up stairs in his office. Therefore, he was ascending .
This means the 10 staircase will be added since there is an increase.
Hence, the absolute value expression for the given statement is as follows:
absolute value = |10|

Answer:
y= -2x+6
Step-by-step explanation:
General formula :
y=mx+c
m is the gradient
when finding when finding the perpendicular line of another line is will be the negative inverse of the gradient
The perpendicular line will have a gradient of -2 (the negative inverse of 1/2)
so
the line perpendicular to the equation y=1/2x+6
is y= -2x+6
Answer:
d) 330
Step-by-step explanation:
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is C(11 , 4)
That is 
ways
by using formula 
now simplification
= 
after cancelling 7! and on simplification
= 
after cancellation we get 330 ways
The number of ways can a dance instructor send 4 of her 11 students to summer dance program is 330
