Answer:
The value of k is 24
Step-by-step explanation:
y = 24x
The equation for a direct variation is
y = kx
The constant of proportionality is k
y = 24x
The value of k is 24
The answer is D. Think back to the quadratic formula
You would plug in values of a, b, and c to find the zeros of the equations. It would the same way in a spreadsheet program where the cells contain the a, b, and c values but you can have more values and a different equation.
Answer:
y = 15.75x + 25 is the linear equation
$88 would be the total cost
Step-by-step explanation:
First, create the equation using y = mx + b, where x is the number of hours:
y = 15.75x + 25 will be the equation, since the charge is $15.75 per hour and the flat fee is $25
There are 4 hours in between 8:30 AM and 12:30 PM, so to find the cost, plug in 4 as x and simplify:
y = 15.75x + 25
Plug in 4 as x:
y = 15.75(4) + 25
y = 63 + 25
y = 88
So, the total cost would be $88
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.
