Step-by-step explanation:

Option D is the correct answer

Because if the blouse is of 8 dollars then 4 blouses = 32 and skirt = 12 so 3 skirts = 36

36 + 32 = 68

Susan bought 6 blouses = 8 x 6 = 48

3 skirts = 12 x 3 = 36

48 + 36 = 84

At which root does the graph of f(x) = (x+4)6(x + 7)5 cross the x axis?
Licemer1 [7]

Answer:

x = -7

Step-by-step explanation:

Our function is f(x) =(x+4)^6(x+7)^5. Notice that our possible roots are when x + 4 = 0 and when x + 7 = 0. So, our roots are -4 and -7.

However, the power above x + 4 is even, meaning the graph will simply <em>touch</em> the x-axis at x = -4, but not pass through. The power above x + 7, though, is odd, which means the graph will <em>cross</em> the x-axis.

Thus, the answer is x = -7.

What are the zeros of the function f(x)=-x^2+13x-36
Galina-37 [17]

For this case we have the following function:

f (x) = - x ^ 2 + 13x-36

To find the zeros of the function we make y = 0and solve for "x", then:

0 = -x ^ 2 + 13x-36

We multiply by -1 on both sides of the equation:

0 = x ^ 2-13x + 36

We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.

(-9) * (- 4) = 36\\-9-4 = -13

Thus, the factored equation is:

(x-9) (x-4) = 0

Therefore, the roots are:

x_ {1} = 9\\x_ {2} = 4

Answer:

x_ {1} = 9\\x_ {2} = 4

Can someone help me with this?

The equilibrium price is $12.

<h3>What is the equilibrium price ?</h3>

Equilibrium is the point where the quantity demanded is equal to the quantity supplied. The price at equilibrium is known as the equilibrium price and the quantity at equilibrium is known as the equilibrium quantity.

When shown on a graph, equilibrium is the point where the quantity demanded curve is equal to the quantity supplied curve.

When there is equilibrium, the equation of quantity demanded would be equal to the equation of quantity supplied.

-280 + 40p = 800  - 50p

In order to determine the value of p, take the following steps:

Combine similar terms: 800 + 280 = 40p + 50p

Add similar terms = 1080 = 90p

Divide both sides of the equation by 90 : 1080 / 90 = 12
