K added to 10 gives you 4 times the value of K.
If you wanted to solve the expression:
Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k
If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.
We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
There are 3 because 12 divided by 4 is 3.
Answer:
It does not represent a function because a vertical line will cross the graph at more than one point.
Step-by-step explanation:
The answer is self-explanatory.
A function maps a value of x to <em>only one</em> value of y. This graph shows two (2) values of y for most values of x in the domain of the relation.
Answer:
The maximum profit is 5070 dollars
Step-by-step explanation:
The profit y is represented by a quadratic function.
The equation that we can use to find a maximum value of a quadratic function is:
Max_value = c - (b^2 / 4a)
Where a, b and c are the coefficients of the quadratic function (in our case: a = -13, b = 770, c = -6332)
So, using this equation, we have:
Max_value = -6332 - (770^2 / 4*(-13)) = -6332 - 592900/(-52)
Max_value = -6332 + 11401.92 = 5069.92
rounding to the nearest dollar, we have that the maximum profit is 5070 dollars.
