10 because the highest negative number would actually be the lowest number
Answer:
a. Graph A: Cost vs Volume
Graph B: Calories vs Volume
b. Graph B (Calories vs Volume)
c. k = 15
Step-by-step explanation:
a. It is not possible for a volume of 10 oz of drink to be sold for $150. It doesn't make common sense. Also, calorie level of 150 in 10 oz of drink seem plausible.
It makes more sense if 10 oz of the drink cost $3.75. Therefore, the graphs should be titled as follows:
Graph A: Cost vs Volume
Graph B: Calories vs Volume
b. The quantities in Graph B (Calories vs Volume) appear to be in a proportional relationship. We know this because if we try drawing a line to connect the points on the graph, it will give us a straight line. A straight line connotes proportionality.
Also the ratio of the quantities of the two known points given are the same. I.e.
Therefore the quantities compared in Graph B shows a proportional relationship.
c. Constant of proportionality =
Answer:
x(0.75)
If you get a 25% discount then you can subtract 25% from 100%, leaving you with 75%. If you multiply the value of x by 0.75, it will give you the final cost.
Answer:
X=5
Step-by-step explanation:
this is because of the pathagorean thereom
a^2+ b^2= c^2
12^2+b^2=13^2
144+b^2=169
b^2= 169-144
b^2=25
the square root of 25 is five
