Answer:
(-4,3）
Step-by-step explanation:
Answer:
11,813
Step-by-step explanation:
PEMDAS
(20x20x30) - 90 + 90 -187 = 12,000
12,000 - 90 + 90 = 12,000
+ 90 and - 90 cancel each other out.
12,000 - 187 = 11,813
Hope this helps!
Perpendicular linees have slopes that multiply to -1
paralell lines have slopes that are the same
also
for ax+by=c
the slope is -a/b
so
<span>10x - 5y = 8? slope is -10/-5=2, paralell so slope of parallell line is also 2 (B)
4x + 2y = 5? slope is -4/2=-2, paralell so slope of paralell line is also -2 (E)
x - 3y = 9? slope is -1/-3=1/3, perpendicular, so 1/3 times -3=-1 (C)
x - 5y = -10? slope is -1/-5=1/5, perpendicular, so 1/5 times -5=-1 (A)
4x + y = -1? </span>slope is -4/1=-4, parallel so -4 (D)
<span>What is the slope of a line parallel to 10x - 5y = 8? B
What is the slope of a line parallel to 4x + 2y = 5? E
What is the slope of a line perpendicular to x - 3y = 9? C
What is the slope of a line perpendicular to x - 5y = -10? A
What is the slope of a line parallel to 4x + y = -1? </span>D
