Answer:
x=1
Step-by-step explanation:
Step 1:Simplify both sides of the equation
4(x-5)+2x=-14
(4)(x)+(4)(-5)+2x=-14
4x+-120+2x=-14
4x+2x+-20-14
6x+-20=-14
6x-20=-14
Step 2: Add 20 to both sides
6x-20+20=-14+20
6x=6
Step 3: Divide both sides by 6
6x/6=6/6
x=1

Step-by-step explanation:
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.
(x-1)^2 + (y-4)^2 = 16
the formula is (x-h)^2 + (y-k)^2 = r^2
