I think the points given here are plotted linearly:
FGHI. in this case, we can tell that FG + GH + HI = FI. substituting to the expression devised, 2 units + GH + 1 unit = 7 units. This is equal to 3 units + GH = 7 units. GH is then equal to 4 units.
Question:
The graph shows the amount of money Miguel earns after working x hours. What is the rate of change of the amount earned with respect to hours worked for this function? hours per dollar hours per dollar 3 dollars per hour 13 dollars per hour
Answer: 13 dollars per hour
Step-by-step explanation:
The rate of change (ROC) for the point defined on the graph can be deduced by calculating the ratio of the difference between the two coordinate points given, similar to calculating the gradient or slope :
Point a = (5, 65) = (x2, y2)
Point b = (2, 26) = (x1, y1)
Calculating the gradient or slope :
Rate of change = (y2 - y1) / (x2 - x1)
Rate of change = (65 - 26) / (5 - 2)
Rate of change = 39 / 3
= 13 dollars per hour
Answer:
Step-by-step explanation:
Given that a store receives shipments of peaches. They want to sort them by weight.
The sorting pattern is as follows:
Peaches : Pound = 2:1 or 3.25:1 or 1:3.25
Given are i) 26 peaches to 13 lbs = 26:13=2:1 Hence goes to the first box
ii) 6 peaches to 19.5 lbs =6:19,5 = 1:3,25 lb. Hence goes to II box
iii) 13 peaches to 4 lbs: =13:4=3.25:1 Hence goes to II box
iv) 39 peaches to 12 lbs: =39:12=3.25:1 Hence goes to II box
v) 15 peaches to 7.5 lbs: =15:7.5=2:1 Hence goes to I box
i - I box
ii - II box
iii - II box
iv) - II box
v) - I box
Let us say that:
x = is the number of ads that Nadia sold every week
P = payment or amount that she receives every week
So the equations we can formulate for choice A and B are:
choice A: P = 110 x
choice B: P = 150 + 85 x
The amount that she receives for A must be greater than
she receives for choice B, so:
110 x > 150 + 85 x (inequality equation)
Calculate for x:
110 x – 85 x > 150
25 x > 150
x > 6
Therefore Nadia must sell more than 6 ads every week so
that Choice A would be the better choice.
