Let’s solve for “a” and “s”.

a = 927 - 45s
a = 792 - 36s

927 - 45s = 792 - 36s
927 - 792 = 45s - 36s
135 = 9s
s = 15
a = 927 - (45 x 15) = 252

Solve the given inequality. Describe the solution set using the set builder or interval notation. Then graph the solution set on
Sophie [7]

Answer: THIRD OPTION.

Step-by-step explanation:

Given the following inequality:

3(x-5)\geq 6

You can follow these steps in order to solve it:

1. Apply Distributive property on the left side:

3(x-5)\geq 6\\\\(3)(x)+(3)(-5)\geq 6\\\\3x-15\geq 6

2. Add 15 to both sides of the inequality:

3x-15+(15)\geq 6+(15)\\\\3x\geq 21

3. Finally, divide both sides of the inequality by 3:

\frac{3x}{3}\geq \frac{21}{3}\\\\x\geq 7

 The symbol is \geq means "Greater than or equal to", and indicates that 7 is  include in the solution.

Therefore, the solution can be expressed as:

[7, \infty)

Now you must mark this point with a closed dot on the number line and shade everything to the right.

Suppose an oligopoly consists of two firms. Firm A lowers price and Firm B responds by lowering its price by the same amount. If
VMariaS [17]

Answer:

The profits for firma A and B will decrease.

Step-by-step explanation:

Oligopoly by definition "is a market structure with a small number of firms, none of which can keep the others from having significant influence. The concentration ratio measures the market share of the largest firms".

If the costs remain the same for both companies and both firms decrease the prices then we will have a decrease of profits, we can see this on the figure attached.

We have an equilibrium price (let's assume X) and when we decrease a price and we have the same level of output the area below the curve would be lower and then we will have less profits for both companies.

Can somebody help me with this question

First, we know that y is equal to -8x, so we can move the -8x to replace y in the first equation, then in the first equation we get -8x=6x-14, subtract 6x on both sides, -14x=-14, x=1
