dry cleaning bill is shown by y equals 1.50 x + 4.50 y is the total cost and x is the number of shirts graph this equation
1 answer:
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
y------> the total cost
x------> the number of shirts
we know that
The linear equation is
------> equation of the line
To graph the line find the intercepts
The y-intercept is the value of y when the value of x is equal to zero
The x-intercept is the value of x when the value of y is equal to zero
<em>Find the y-intercept</em>
For x=0
The y-intercept is the point (0,4.50)
<em>Find the x-intercept</em>
For y=0
The x-intercept is the point (-3,0)
Plot the intercepts to graph the line
see the attached figure

Answer:
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
Step-by-step explanation:
Formulas are used to factorize the polynomials.
In the given question, we can see a difference of squares
the difference of squares can be factorized using the formula
Here a^2 and b^2 are squares and factorized as sum and difference of numbers.
So in the given options,
(4x + 3)(4x - 3) represents the factorization of a polynomial that was the difference of two squares as it is written as product of sum and difference of two numbers.
