Answer: Option B.

Step-by-step explanation:

Given the system of inequalities:

$y$

$y>x^2-4$

The solution of the system of inequalities is the region between the parabolas. This region is: below the parabola $y=x^2+6$ and above the parabola $y=x^2-4$

Then, if a point is a solution of the system, then it must be in the region between this parabolas.

You can observe in the figure attached that the point that is in this region is the point (2,6), therefore, the answer is the option B.

Cost per unit = $59

Let x units of product be sold.

We have to write an expression the amount of money received (revenue R) from the sale of x units of the product.

Revenue:

It is the total income and is obtained by multiplying the quantity of goods sold by the unit price of the goods.

Revenue =

If j and k are intersecting lines, A and B are points on j, and C and D are points on k, how many planes contain points A, B, C,

ValentinkaMS [17]

The correct answer to this question is letter "B. We can't determine from the given information."

Using the information as stated, "If j and k are intersecting lines, A and B are points on j, and C and D are points on k," the number of planes that contain points A, B, C, and D cannot be determined because of the lack of information.

Answer:

x=70°

Step-by-step explanation:

Three triangles can be made out of that shape so total int. angles = 3 x 180°=540°.

so 40 + 110 + 4x + 40 + x = 540°

190+5x=540°

5x=350°

x=350/5=70°
