Answer:
270°
Step-by-step explanation:
360/4 = 90
90*3 = 270
4-2=2
6*2=12
2+12=14
14 is the answer
Answer:
63 + 10
Step-by-step explanation:
when you do parenthesis and the number is next to another one with no symbol you multiply so 4-2 = 2 2 x 5 = 10 giving you 63 + 10
Answer:
parallel:

perpendicular:

Step-by-step explanation:
original line:
-7x + 8y = 4
m = 7/8
parallel:
m = 7/8
L: 7x - 8y = k
(4, -4) -> L
28 + 32 = 60 = k
L: 7x - 8y = 60
perpendicular:
m = -8/7
L: -8x + 7y = k
(4, -4) -> L
-32 + 28 = -4 = k
L: -8x -7y = -4
=> 8x + 7y = 4
Answer:
-9/13
Step-by-step explanation:
The formula for slope is [ y2-y1/x2-x1 ].
10-(-3)/-5-4
13/-9
-9/13
Best of Luck!
