Answer:

The equation of the line is y - 16 = 3(x - 3)

Step-by-step explanation:

To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.

m(slope) = (y2 - y1)/(x2 - x1)

m = (16 - 4)/(3 - -1)

m = (16 - 4)/(3 + 1)

m = 12/4

m = 3

Now that we have the slope, we can use it and either point in point-slope form.

y - y1 = m(x - x1)

y - 16 = 3(x - 3)

A retail company estimates that if it spends x thousands of dollars on advertising during the year, it will realize a profit of

Gwar [14]

Answer:

Step-by-step explanation:

If the profit realized by the company is modelled by the equation

P (x) = −0.5x² + 120x + 2000, marginal profit occurs at dP/dx = 0

dP/dx = -x+120

P'(x) = -x+120

Company's marginal profit at the $100,000 advertising level will be expressed as;

P '(100) = -100+120

P'(100) = 20

Marginal profit at the $100,000 advertising level is $20,000

Company's marginal profit at the $140,000 advertising level will be expressed as;

P '(140) = -140+120

P'(140) = -20

Marginal profit at the $140,000 advertising level is $-20,000

Based on the marginal profit at both advertising level, I will recommend the advertising expenditure when profit between $0 and $119 is made. At any marginal profit from $120 and above, it is not advisable for the company to advertise because they will fall into a negative marginal profit which is invariably a loss.

QUADRATIC EQUATION â€" WORD PROBLEMS

dusya [7]

Answer: -7, 12

Step-by-step explanation:

a+b = 5

a*b = -84

a = 5-b

(5-b)*b = -84

-b^2 + 5b + 84 = 0

(-b - 7)(b + 12) = 0

The roots are -7 and 12.

Answer:

2 1/6x +10

Step-by-step explanation:

All you need to do is combine like terms.

3/2x+4+2/3x+6

3/2x+10+2/3x

3/2x + 2/3x= 2 1/6x

2 1/6x+10
