Answer:
y=2x+3
Step-by-step explanation:
Y is the total amount that the family pays. 2x represents 2 dollars for every person (so, 2 multiplied by the number of people). Finally, 3 represents the initial amount that they must pay, no matter how many are in the car.
The product means you multiply, so:
-y × 6x = -6xy
-y × 4y = -4y²
x × 6x = 6x²
x × 4y = 4xy
= -2xy - 4y² + 6x
I hope this helps!
Answer:
The value of y would be 45.5
Step-by-step explanation:
To solve this problem, start with the base form of direct variation.
y = kx
Now we can use our original values to model the equation and find k.
35 = k(2.5)
14 = k
Now we can model the equation as:
y = 14x
Now to find y, when x = 3.25, simply put 3.25 into the equation.
y = 14(3.25)
y = 45.5
I would tell you how to do it but its a very hard thing to explain
8(1-8p) + 8p
8 - 64p + 8p
8 - 56p
8 = 56p
1/7 = p
