Answer:
m = 6 7/8 or 55/8.
Step-by-step explanation:
6= m - 7/8
6 + 7/8 = m - 7/8 + 7/8
m = 6 7/8 or 55/8.
Answer:
y = 1/2x -3
Step-by-step explanation:
The slope of the given line is the x-coefficient: -2. The slope of the perpendicular line is the negative reciprocal of this:
-1/(-2) = 1/2
The only answer choice with a slope of 1/2 is ...
y = 1/2x -3
Answer:
The possible ways Daniel line up his rock collection are {2, 3, 6 and 9}.
From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x
1meter=100centimeter
1centimeter=1/100meter
so cm times 1/100=meters
43 times 1/100=43/100meters aka 0.43 meters
43/100 or 0.43 meters
