Answer:
y=-1.9x-1
Step-by-step explanation:
This is the additive identity property or identity property of addition.
This property states that when you add 0 to a number, the result is the original number.
Answer:
297 miles
Step-by-step explanation:
cost = 0.78 cents per mile + base fee
y = 0.78x + 15.88
247.65 = 0.78x + 15.88
subtract 15.88 from both sides
231.77 = 0.78x
divide by 0.78 on both sides
x = 297.14120256
297 miles

Answer:
Both Carlos and Irene
Step-by-step explanation:
Given the expression (28x - 8)
Carlos : 2(14x - 4)
Danny : 7(4x - 1)
Irene : 4(7x - 2)
The factored expression Given by Carlos, Irene and Danny can be expanded to check if it gives the same expression as that Given in the question :
Carlos :
2(14x - 4)
2*14x - 2*4
28x - 8
Danny :
7(4x - 1)
7*4x - 7*1
28x - 7
Irene :
4(7x - 2)
4*7x - 4*2
28x - 8
From.the expanded solutions obtained ;
Both Carlos and Irene's solution corresponds to the factored form of the original equation and are Hence correct
The value of x is 0.2. 35 x 0.2 = 7
