Answer:

C) 6

Step-by-step explanation:

13 + (-12) - (-5) = 13 + (-12) + 5

                       = 1 +5

                      = 6

13 & (-12 ) have different sign, so subtract and put the sign of the greater number's sign.

Slope = 2/3, passing through (7,4). Write an equation for the line in point-slope form.
Marat540 [252]

Answer:

y - 4 = (2/3)(x - 7)

Step-by-step explanation:

(see attached for reference)

we are given slope, m = 2/3 and point (x₁, y₁) is (7,4)

y - y₁ = m(x - x₁)

substituting the given values into the general equation

y - y₁ = m(x - x₁)

y - 4 = (2/3)(x - 7)

Amanda composed 2 songs. The longer song is 126 seconds less than twice the length of the short song. The longer song lasts 286
xxMikexx [17]

LongSong = 286s

LongSong = 2 * ShortSong - 126s

=>

2 * ShortSong - 126s = 286s

2 * ShortSong = 286s + 126s

2 * ShortSong = 412s

ShortSong = 206s
