Answer:
a. (5,5)
b. (-5,-5)
Step-by-step explanation:
reflection over x-axis flips the sign of y-coordinate
reflection over y-axis flips the sign of x-coordinate
Step-by-step explanation:
(4x-5)(4x+5)
multiply each
4x×4x=16x^2
4x×5=20x
-5×4x= - 20x
-5×5= -25
16x^2+20x-20x-25
16x^2-25
Calculate the absolute differences
1-5/6=1/6
6/5-1=1/5
since 1/6 is less than 1/5 5/6 is closer
Answer:
{-6, 12}
Step-by-step explanation:
Assuming that you meant (1/3), then you have:
(1/3)|3x - 9| - 5 = 4
First, let's combine the -5 and the +4:
(1/3)|3x - 9| = 9
Next, multipy both sides by 3 to eliminate the fraction 1/3:
|3x - 9| = 27
This absolute value equation has two separate parts:
3x - 9 = 27, and
-(3x - 9) = 27.
In the first case, we have x - 3 = 9, or x = 12.
In the second case, we have -3x + 9 = 27, or -3x = 18, or x = -6.
The solution set is {-6, 12}.
