What is (f - g)(x)?<br> f (x) = 24 – 22 + 9<br> 9(2) = 23 + 3x2 + 12<br><br><br> (f - g)(x) = ???
bija089 [108]

Answer:

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

Step-by-step explanation:

Subtract  g(x)=x^3 + 3x^2 + 12 from f(x)= x^4 - x^2 + 9

First, take the negative of every term (including the label g(x) ) of g(x), obtaining  -g(x) = -x^3 - 3x^2 - 12.

Now combine this result with f(x):

 f(x)= x^4 - 0x^3 - x^2 + 9

-g(x) =       - 1x^3 - 3x^2 - 12

---------------------------------------

(f - g)(x) = x^4 - x^3 - 4x^2 - 3

May i get help on this im sort of doing bad in this subject so thanks!
klasskru [66]

Answer:

1. 500mg

2.A watermelon weighs about 3 (grams /(kilograms) 3.

3. 500 oranges

4. 30 weeks

5. 1500

Step-by-step explanation:

1. Therefore, 0.5 g=0.5*1000=500 mg

2. A watermelon weighs about 3 (grams /(kilograms) 3.

3.Weight of the box- 40 kg

Weight of 1 orange-80

Therefore, no. of total oranges=

40 kg=40000g

Now, 40000÷80

= 500

4. 500g x 2 is 1000 g and is 1kg

105-90 is equal to 15kg

500 x 30 is 15000 g is equal to 15 kg

5. divide by 4 to get the mass of a single bag and then multiply by 1000 to get to grams from kilograms

6/4=1.5

1.5*1000=1500

therefore a single bag of sugar weighs 1500 grams

Kristen can run at 15 km/h and walk at 5 km/h. She complete for a 42 km marathon in 4 hours. What distance did Kristen run durin
maksim [4K]
Let x be the time she ran and y be the time she walked 

then distance ran =  25x and distance walked = 5y 

so 15x + 5y = 42

and x + y = 4

* second equn. by -5:-

-5x - 5y = -20

add this to the first equn:0

10x = 22
x = 2.2

distance she ran = 2.2 * 15  =  33 km
