Answer:
see below
Step-by-step explanation:
-2x + 9 < x − 9
Add 2x to each side
2x-2x + 9 < 2x+x − 9
9 < 3x-9
Add 9 to each side
9+9 < 3x
18 < 3x
Divide each side  by 3
18/3 < 3x/3
6 < x
Open circle  at 6 line going to the right
 
        
             
        
        
        
Hello!
To find the equation of a line parallel to y = 3x - 3 and passing through the point (4, 15), we need to know that if two lines are parallel, then their slopes are equivalent. 
This means that we create a new equation in slope-intercept form, which includes the original slope, which is equal to 3. 
In slope-intercept form, we need a y-intercept. So, we would substitute the given ordered pair into the new equation with the same slope and solve. 
Remember that slope-intercept form is: y = mx + b, where m is the slope and b is the y-intercept. 
y = 3x + b (substitute the ordered pair (4, 15))
15 = 3(4) + b (simplify) 
15 = 12 + b (subtract 12 from both sides) 
3 = b 
Therefore, the equation for the line parallel to the line y = 3x - 3, and passing through the point (4, 15) is y = 3x + 3. 
 
        
             
        
        
        
Answer:
(-12, -1)
Step-by-step explanation:
(8, -1) => (-2/3x, f(-2/3x)) 
therefore 
-2/3x = 8
x = 8 *-3/2
x = -12
f(-2/3x) = -1
therefore, the corresponding point is:
(-12,-1)
