(33/7) / (1 13/14)
= (33/7)/ (27/14)
= (33/7)* (14/27)
= 22/9
= 2 4/9
The final answer is 2 4/9~
X+y is less than or equal to 15
4x+8y is greater than or equal to 80
x is greater than 0
y is greater than 0
Answer:
D) y = -1/3x - 7
Step-by-step explanation:
This graph has a negative slope, so immediately you can eliminate A.
Let's find the slope first. One point is (0,-7) and the other can be (-3,-6).
(-6+7)/(-3-0) = 1/(-3) = -1/3
Because the slope is -1/3, you can eliminate C.
Let's look at the y-intercept next. When x = 0, y = -7.
The answer would be B! This is because when multiplying 350 by .7, you are taking away the 30% which was originally part of the 350. Hope this helps!
Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
