If you understand what is linear pair, you can see the same in triangle also. A linear pair is a pair of adjacent, supplementary angles. Adjacentmeans next to each other, and supplementary means that the measures of the two angles add up to equal 180 degrees.
X over 2 = -7 comes out to
x
---- = -7. Mult. both sides by 2 to eliminate the fraction:
2
x = 2(-7) = - 14 (answer)
ANSWER
D.
EXPLANATION
The standard equation of the hyperbola is
We multiply through by 36 to obtain:
We now expand to get,
Expand :
To get the general form, we equate everything to zero to get,
The correct choice is D.
50/x
I am confused of what you are asking?
2.3 * 6.9 =
= 2 3/10 * 6 9/10 =
= 23/10 * 69/10 =
= 1587/100 =
= 15 87/100 =
= 15,87
6.9 ÷ 2.3 =
= 6 9/10 ÷ 2 3/10 =
= 69/10 ÷ 23/10 =
= 69/10 * 10/23 =
= 3/10 * 10/1 =
= 3/10 * 10 =
= 30/10 =
= 3
Both problems are done with numbers 2.3 and 6.9, however the multiplying seems to be more complex because the result is a decimal instead a whole number. Hopefully that's what you meant :)
