can some one simplify for x
12=7x+6-5x

Answers

Answer:

x = 3

Step-by-step explanation:

12 = 7x + 6 -5x        {Combine like terms}

12 = 7x - 5x + 6

12 = 2x + 6           {Subtract 6 from both sides}

12 - 6 = 2x

      6 = 2x                  {Divide both sides by 2}

    6/2 = 2x/2

Let f(x)=5x-4 and g(x)=x^2-1. Find (g*f)(-1)

Answers

Answer:

D. 80

Step-by-step explanation:

Given:

f(x) = 5x - 4,

g(x) = x² - 1

Required:

(g o f)(-1)

SOLUTION:

(g o f)(-1) = g(f(-1))

Plug in -1 for x into the function, f(x) = 5x - 4:

g(f(-1)) = g(5(-1) - 4)

= g(-5 - 4)

= g(-9)

Plug in -9 for x in the function, g(x) = x² - 1

g(-9) = (-9)² - 1

= 81 - 1

= 80.

Therefore, (g o f)(-1) = g(f(-1)) = 80

D. 80 is the correct answer.

Soccer ball profit
y=-6x^2 + 100x - 180
Suppose the store wants to earn a daily profit of $150 from the sale of soccer balls. To earn this profit, what price should the store charge for each soccer ball? Explain how to solve this problem.

Answers

Answer:

$8.33 per soccer ball.

Step-by-step explanation:

Y max is =236.67   is the max profit from the soccer balls. This goes on when you charge 8.33 a ball

Answer:

need to solve the equation 150 = -6x2 + 100x - 180. I can subtract 150 from both sides and use the quadratic formula to find x = 4.53 and 12.13. This means that if the store sells soccer balls for $4.53 or $12.13, it will earn a daily profit of $150.

There are two options for buying crickets option A.7 pounds of crickets for 3.15 option B.3 pounds of crickets for 1.47 which option is better to buy justify your answer

Answers

Answer: 7

pounds for 3.15 is a better option

Step-by-step explanation:

Here in this question, we want to know which of the two options is a better option for buying crickets.

To know the better option, we shall be needing the unit price in whatever system to be used;

7 pounds of crickets for 3.15;

so the unit price here will be 3.15/7 = 0.45 per pound

For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound

As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

What is the equation of the graph shown?​

Answers

Greetings from Brasil...

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

A = ΔY/ΔX

B = where the line intersects the Y axis

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

F(X) = 2X - 3
