Answer:
-2x + 4y = 16.
Step-by-step explanation:
y = 2/4x+ 4 Multiply through by 4:
4y = 2x + 16
-2x + 4y = 16 is the standard form.
Answer:
A
Step-by-step explanation:
Slope intercept form is
y=mx+b
y is y
3x is mx
and
b is 2
The rate of the passenger train is 81.67 MPH and the rate of the freight train is 66.67 MPH.
<h3>What is a linear equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The distance traveled by passenger train = 245 miles
The distance traveled by freight train = 245 miles
The time takes for both trains is the same.
Let's suppose the rate of the passenger train is x and the rate of the freight train is y;
As we know,
Distance = speed×time
245/x = 200/y
200x = 245y
200x - 245y = 0 ..(1)
x = 15 + y ..(2)
Equations (1) and (2) represent the situation.
After solving equations (1) and (2):

Thus, the rate of the passenger train is 81.67 MPH and the rate of the freight train is 66.67 MPH.

The answer is x = z/w - c/w
Answer:
Is to give us a range of values for our estimated population parameter rather than a single value or a point estimate.
