Answer:
The expression is equal to
Step-by-step explanation:
Let
x ----> the number of hours that the roller blades are rented
y ----> the cost of renting roller blades in dollars
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value of the linear equation
In this problem we have
The slope is equal to
The y-intercept is equal to
----> value of y when the value of x is equal to zero
substitute
For x=h hours
substitute
Answer:
Step-by-step explanation:
The given expression is
First of all we make groups
Take GCF from each group
Now, we can factored out the common term
Hence, the resulting expression is
A student ticket cost $4 which is half the price of a full price ticket
Domain is the set of x values in which the graph of a function exists. If the domain is all real numbers; that means there are no gaps in the graph. The only time the domain is not ARN is when there is a square root, denominator, or log/ln. Anything under a square root must be positive. The denominator cannot be equal to zero. A log function must be strictly positive. Therefore all of the equations listed above apply.
Answer:
The equation is y = -x + 4
Step-by-step explanation:
This is a very trivial exercise:
The general equation of a line is given by:
y - y₁ = m(x - x₁)
where m = slope of the linear graph
From the given graph, it can be observed that the coordinate (x₁, y₁) and (x₂, y₂) are (0, 4) and (4, 0)
The slope, m = (y₂ - y₁)/(x₂ - x₁)
m = (0 - 4)/(4 - 0)
m = -4/4
m = -1
Substituting the values of (x₁, y₁) = (0, 4) and m = -1 into the general equation:
y - y₁ = m(x - x₁)
y - 4 = -1 (x - 0)
y - 4 = -x
y = -x + 4
