Answer:
y = 0.87x + 0.02
Step-by-step explanation:
Euros as a function of dollars means that euros is y and dollars are x.
We are given 2 points: (4, 3.5) and (10, 8.72)
slope = (8.72 - 3.5)/(10 - 4)
slope = 5.22/6 = 0.87
y = 0.87x + b
3.5 = 0.87(4) + b
b = 0.02
y = 0.87x + 0.02
Good evening ,
Answer:
The weight : 29 pound
Alan would pay for his dinner : $130
Step-by-step explanation:
Let x represent the weight of the lobster
the cost of the dinner at restaurant 1 is 4x + 14
the cost of the dinner at restaurant 2 is 3x + 43
Now ,we have to solve the equation : 4x + 14 = 3x + 43
4x + 14 = 3x + 43
⇔ x = 43 - 14
⇔ x = 29
In this case Alan would pay the same amount for his dinner at any restaurant:
the price = 4×(29)+14 = 130
= 3×(29)+43 = 130.
