That represents an easy direct division, we divide:
$22.85 / 17 boxes = 22.85/17
= 1.34 dollars per box of crayon
that is the cost
Answer:
B
Step-by-step explanation:
I'm pretty sure its b because its ratio matches the (4,2)
[(upper legth + lower length) x height] divided by 2
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
