Answer:
x=6 , y=17
Step-by-step explanation
3x-1=2x+5
+1 -2x
x=6
plug in 6 for x to solve y
Answer:
The slope of a line parallel to this line will be: -7/9
The slope of the perpendicular line will be:

Step-by-step explanation:
We know the slope-intercept form

Here,
Given the equation

simplifying to write in the lope-intercept form

Thus, the slope of the line is: -7/9
The slope of a line parallel to the line:
We have already determined that the slope of the line is: -7/9
- We know that the parallel lines have the same slope.
Thus, the slope of a line parallel to this line will be: -7/9
The slope of a line perpendicular to the line:
We have already determined that the slope of the line is: -7/9
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.
Thus, the slope of the perpendicular line will be:

Step-by-step explanation:
Do you mean
or
?
Use the formula
where
is the amplitude,
is the phase shift,
is the vertical shift, and the period is
.
Assuming your first case is true, the amplitude would be
, your period is
, and your midline/vertical shift is
.
Assuming your second case is true, everything but the vertical shift stays the same. It would be
in this case.
