I got x= 19.6
Step-by-step explanation:
Answer:
Since each Ticket cost $45 , then the number of ticket sold should be multiplied by the cost of 1 ticket , from the question, it was said that x tickets were sold, i.e the amount will be $45 multiplied by x , which is $45x. To find the profit , then we must find the cost of 18 tickets which will give us the cost price and then subtract it from the selling price ($45x).
The cost of 18 = 18 x $45 = $ 810
profit = $45x - 810
i.e y = 45x -810
clearly, comparing with the equation y = mx +c , we have a slope and y-intercept

Answer: y+ 7 = 5x
Step-by-step explanation:
A linear function is a function in which the highest power of the unknown is 1 , that is , the highest power of the variables that are unknown will be 1.
From the question given:
A : 1 - 
= -y
The power of x is 2 , though the power of y is 1 but because of the existence of the power of x which is 2 , it is not linear
B : y + 7 = 5x
both the power of x and y is 1 , so it is a linear function
C: 
+ 4 = y is not linear
D is also not linear
likewise , E is not linear
Therefore , B is the only linear function
Answer:
Step-by-step explanation:
Putting value of x = 1/2 in the equation
8x - 3/x
8(1/2) - 3(1/2)
= 4 - 3/2
= 2.5 or 5/2
