THat would be A , B, C and E
Y = 1/3x ? 6....slope here is 1/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3 (see how I flipped 1/3 and changed the sign)
y = mx + b
slope(m) = -3
(-9,12)...x = -9 and y = 12
now we sub and find b, the y int
12 = -3(-9) + b
12 = 27 + b
12 - 27 = b
-15 = b
so ur perpendicular equation is : y = -3x - 15
1/4 # hamburger = 16 oz to a pound so 1/4 is 4 oz.
1 doz baseballs (12), 5 oz each
Box = 9 oz.
Total weight = 12x5 = 60 oz. + 9 oz. = 69 oz.
69/16 = 4 lb. 5 oz.
Triangle, rectangles, pollygon, robtuse, i hope this is what you mean
Answer:
the answer to your question is 'b'
