f(x) = 2x3 + 5x2 - 6x - 7
g(x) = 2x - 3
Find (f - g)(x).
Step-by-step explanation:
its C. cause if f -g is equal to positive 4
Option B → (f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4 is correct.
We have the following functions -
f(x) = [tex]2x^{3} +5x^{2} -6x-7[/tex]
g(x) = 2x - 3
We have to determine (f - g)(x).
Define function in Mathematics.In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.
According to the question, we have -
f(x) = [tex]2x^{3} +5x^{2} -6x-7[/tex]
g(x) = 2x - 3
Now -
(f - g)(x) = {[tex]$2x^{3} +5x^{2} -6x-7[/tex] - (2x - 3)}
(f - g)(x) = {[tex]$2x^{3} +5x^{2}[/tex] - 6x - 7 - 2x + 3}
(f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4
Hence, Option B → (f - g)(x) = [tex]$2x^{3} +5x^{2}[/tex] - 8x - 4 is correct.

Explain how to get the variable alone in the equation. 3x = 24
Answer:
to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

A parabola can be drawn given a focus of (4, -3) and a directrix of y=5 Write the equation of the parabola in any form.
Answer:
The equation of the parabola is (x - 4)² = -16(y - 1)
Step-by-step explanation:
The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where
The vertex of the parabola is (h, k)The focus is (h, k + p)The directrix is at y = k - p∵ The focus of the parabola is (4, -3)
∵ The focus is (h, k + p)
∴ h = 4
∴ k + p = -3 ⇒ (1)
∵ It has a directrix of y = 5
∵ The directrix of the parabola is y = k - p
∴ k - p = 5 ⇒ (2)
→ Add equations (1) and (2) to find k and p
∵ (k + k) + (p - p) = (-3 + 5)
∴ 2k + 0 = 2
∴ 2k = 2
→ Divide both sides by 2
∴ k = 1
→ Substitute the value of k in equation (1)
∵ 1 + p = -3
→ Subtract 1 from both sides
∴ 1 - 1 + p = -3 - 1
∴ p = -4
∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)
→ Substitute the values of h, k, p in it
∴ (x - 4)² = 4(-4)(y - 1)
∴ (x - 4)² = -16(y - 1)
∴ The equation of the parabola is (x - 4)² = -16(y - 1)

Katrina is going to order sweatshirts for her girls mentoring group. The sweatshirts will have the group logo printed on the front. Katrina asks two local companies to give her a price.
• MH Designs will charge $21.50 for each of the sweatshirts.
• Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.
Justify how to determine the number of sweatshirts Katrina would need to order from
each company for the costs to be the same.
Answer:
Katrina would need to buy 20 sweatshirts.
Step-by-step explanation:
The number of sweatshirts Katrina would need to order from each company can be determined by forming the linear equation in two variables.
Given :
Katrina is going to order sweatshirts for her girl's mentoring group.Katrina asks two local companies to give her a price.MH Designs will charge $21.50 for each of the sweatshirts. Print Rich will charge $18 for each sweatshirt plus a one-time setup cost of $70.Let the number of sweatshirts orders from company MH Designs be 'x' and the number of sweatshirts orders from company Print Rich be 'y'.
So, the cost for ordering the sweatshirt from the company MH Design is:
[tex]21.50x = c[/tex]
Now, the cost for ordering the sweatshirt from the company Print Rich is:
18y + 70 = c'
Given that the number of sweatshirts Katrina would need to order from each company for the costs to be the same. So :
21.5x = 18y + 70
Now, put the value of x and y so, that in the above equation, both sides become equal.

the manager of a symphony computes that the symphony will earn -40p^2+1100p dollars per concert if they charge P dollars for tickets. what ticket price should the symphony charge in order to maximize its profits?
Answer:
$7,562.5
Step-by-step explanation:
Given the function of the profit earned expressed as;
f(p) =-40p^2+1100p
To maximize the profit, df(p)/dp must be sero
df(p)/dp = -80p + 1100 = 0
-80p + 1100 = 0
-80p = - 1100
p = 1100/80
p = 13.75
Substitute p = 13.75 into the function
f(13.75) =-40(13.75)^2+1100(13.75)
f(13.75) = -7,562.5+15,125
f(13.75) = 7,562.5
Hence the symphony should charge $7,562.5 to maximize the profit.
