The slope formula is: m= (y2 - y1) / (x2 - x1)<span>
Therefore, m= (-3-6) / (5- -2)
m= (-9)/(7)
m= -9/7 (Go up 9 spots, to the left 7 spots) OR m= -1.29 (Rounded)

To solve
if you have |a|=b, solve a=b and a=-b
|4x+12|=16
solve
4x+12=16 and 4x+12=-16
minus 12 both sides
4x=4 and 4x=-28
divide both sides by 4
x=1 and x=-7
Answer: 640
Step-by-step explanation:
8 x 8 x 9 + 1/3 (8 x 8 x 3)
= 640 in cubic ft
Answer:
w = 63; x = 86; y = 38; z = 25
Step-by-step explanation:
Find w:
117 + w = 180 (linear pair)
w = 63
Find x:
x + w + 31 = 180 (sum of measures of interior angles of triangle is 180)
x + 63 + 31 = 180
x = 86
Find y:
x + y + 56 = 180 (sum of measures of three angles equals 180 deg)
86 + y + 56 = 180
y = 38
Find z:
y + z + 117 = 180 (sum of measures of interior angles of triangle is 180)
38 + z + 117 = 180
z = 25
