For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor because it's the power of s with the smallest denominator. So, we have
Step 1 ax2 + bx + c = 0

The final price inculding tax after discount is $ 47 and expression used is:
Required expression = price of item - discount price + tax on item
<h3><u>Solution:</u></h3>Given that 40% discount on an item costing $74 plus 7% tax
So cost of item = $ 74
Tax = 7 %
Discount = 40 %
The expression which can be used to find price after discount including tax is:
Required expression = price of item - discount price + tax on item
Let us first find the price after discount
Price after discount = cost of item - 40 % of cost of item
Price after discount = 74 - 40 % of 74
Thus the price after discount is approximately $ 44
<em><u>Now tax is 7 % which means 7 % of $ 44</u></em>
Price including tax = 44 + 7 % of 44
Price including tax =
Thus the final price inculding tax after discount is $ 47
Answer:
The correct options are A, D and E.
Step-by-step explanation:
We are given the function
From the graph below, we see that,
Domain and range of the function is the set of all real numbers.
<em>As y-intercept is the point where the graph of the function crosses y-axis.</em>
That is, y-intercept is obtained when x= 0.
So, on substituting, we have,
i.e.
i.e. y= 1
Thus, the y-intercept is (0,1).
<em>Also, x-intercept is the point where the graph of the function crosses x-axis.</em>
That is, x-intercept is obtained when y= 0.
So, on substituting, we have,
i.e.
i.e.
i.e. x= -7
Thus, the x-intercept is (-7,0).
Hence, the correct options for the function are,
A. The graph has a domain of all real numbers.
D. The graph has a y-intercept at (0, 1)
E. The graph has an x-intercept at (–7, 0).
