Find(f+g)(x) for the following functions. f(x) = 12x2 + 7x + 2 g(x) = 9x + 7
Nimfa-mama [501]

Answer:

(f + g)(x) = 12x² + 16x + 9 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- We can add and subtract two function by adding and subtracting their

 like terms

Ex: If f(x) = 2x + 3 and g(x) = 5 - 7x, then

     (f + g)(x) = 2x + 3 + 5 - 7x = 8 - 5x

     (f - g)(x) = 2x + 3 - (5 - 7x) = 2x + 3 - 5 + 7x = 9x - 2

* Lets solve the problem

∵ f(x) = 12x² + 7x + 2

∵ g(x) = 9x + 7

- To find (f + g)(x) add their like terms

∴ (f + g)(x) = (12x² + 7x + 2) + (9x + 7)

∵ 7x and 9x are like terms

∵ 2 and 7 are like terms

∴ (f + g)(x) = 12x² + (7x + 9x) + (2 + 7)

∴ (f + g)(x) = 12x² + 16x + 9

* (f + g)(x) = 12x² + 16x + 9

Answer: 147 cm²

Step-by-step explanation:

   Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.

A = πr²

A = (3)(7)²

A = 147 cm²

Help me on problem 7a and b plz
yanalaym [24]

Remark

The easiest way to graph this is to get a program to do it for you. Desmos is ideal.

Problem 7a

The graph is down  below the rest of the answer. 5x + 2y = 150

<u>x and y intercepts.</u>

The x intercept is marked as 30. That was derived by letting y = 0 to get

5x = 150   divide by 5

x = 150 / 5

x =  30

So if you buy NO wristbands, you can get 30 keychains

The y intercept occurs when x = 0

2y = 150    Divide by 2

y = 150 / 2

y = 75 That means if you buy NO keychains, you can buy 75 wrist bands.

Problem 7b

For this problem x = 18

5*18 + 2y = 150

90 + 2y = 150        Subtract 90 from both sides.

2y = 150 - 90

2y = 60                  Divide by 2

y = 60/2

y = 30

Conclusion

You can buy 18 key chains (given)

You can buy 30 wristbands (calculated)
