Since they are perpendicular the slopes of the two lines must be opposite (meaning they must have opposite signs such as "1" and "-1") as well as be reciprocals (meaning the fraction must be flipped, in example with this problem as the reciprocal of "-4/3" is "-3/4")
the slope of line L must be 3/4
Answer:
A'(-3, 5), B'(1, 7), C'(2, 3)
Step-by-step explanation:
The rule 
means to subtract 1 from all the <em>x</em>-coordinates and add 2 to all the <em>y</em>-coordinates. (It also means move each point 1 unit to the left and 2 units up.)
Answer:
25%
Step-by-step explanation:
Step one:
A store normally sells certain dress for $160 during a special sale
the store reduces the price of the dress to $120
Step two:
Percent reduction= change in price/initial price *100
Percent reduction= 160-120/160 *100
Percent reduction= 40/160*100
Percent reduction==0.25*100
Percent reduction=25%
I would word it ...
"nine times the sum of x and the square of y is eighteen".
As a math sentence, it looks like
... 9(y^2 +x) = 18
or
... 9(y² +x) = 18
