Answer:
y = -140
Step-by-step explanation:
Y varies directly with x
y = kx
We know y = -20 when x =2, we can solve for k
-20 = k*2
Divide each side by 2
-20/2= 2k/2
-10 =k
y = -10x
Now we want to find y when x = 14
y = -10 *14
y = -140
Answer:
sorry i am trying but i don't know what to do
Step-by-step explanation:
All you have to do is 14*.30 which equals to $4.20
To answer this item, we are instructed that the price of the ticket for the children is equal to x. Since, we are also given that this is 5.75 less than the price of tickets for the adults, we may express this as follows,
x = n - 5.75
n is the price of ticket for the adults. This can be calculated by transposing 5.75 to the other side of the equation,
n = x + 5.75
The answer is the third choice.
