Step-by-step explanation:

( vertically opposite angles)



Answer:
4/x^7
Step-by-step explanation:
4x^-7 = 4* x^-7 = 4* 1/x^7 = 4/x^7
The length of RT=12÷2=6cm
the length of PT
6^2+PT^2=12^2
PT=√108
PT=10.392 decimal places
Answer:
y = x/2 - 4 slope-intercept form
y = x/2 + 4 slope-intercept form
NO SOLUTION.
The graph is a pair of parallel lines one line through point (0, -4) and the other through point (0, 4)
Step-by-step explanation:
x - 2y = 8 and -2x+4y=-16.
we can easily convert these to slope intercept form
x - 2y = 8
-2y = 8 - x
2y = x - 8
y = x/2 - 8/2
y = x/2 - 4 slope-intercept form
------------------------------
-2x + 4y = 16
4y = 2x + 16
y = 2x/4 + 16/4
y = x/2 + 4 slope-intercept form
We have 2 lines that are parallel because they have the same slope
