Answer:
Equation of line is
Option A is correct.
Step-by-step explanation:
We need to write an equation that represents the line that passes through the point (-1, 6) and has a slope of -3.
The equation will be of slope-intercept form:
where m is slope and b is y-intercept
We are given slope m =-3, we need to find y-intercept b
Finding y-intercept
using slope m=-3 and point (-1, 6)
So, y-intercept b is 3
Now the equation of line having slope m= -3 and y-intercept b = 3 is
Equation of line is
Option A is correct.
Answer:
Sales = n ($x + $y)
Step-by-step explanation:
The basic simple sales equation is
Quantity Price = Sales
Here in the given question,
Total quantity of sales = n
Price = Cost + markup
(Markup refers to the profit added to cost)
Thus price = $x (cost) + $y (markup)
Sales = n ($x + $y)
Sales amount is the total amount received from sales of products, total quantity at some price provided.
Answer:
Step-by-step explanation:
Not sure what form you need this in, but it really doesn't matter, as you'll see in the final equation. I used the vertex form and solved for a:
We are given the vertex (h, k) as the origin (0, 0), and we have a point that the graph goes through as (4, -64). That's our x and y. Plugging in what we have:
gives us
-64 = 16a and
a = -4. That means that the quadratic equation is
which is both vertex form and standard form here, no difference.
