Given the functions below, what is f(x)−g(x) ?f(x)=7x3−10x2−5g(x)=2x3+7x2−9
A
5x3−17x2+4

B
5x3−3x2−14

C
9x3−3x2−14

D
5x3−17x2−14

Answers

Answer 1
Answer:

Answer:

f(x)-g(x)=5x^3-17x^2+4 which appears as option A

Step-by-step explanation:

Simply subtract the function's expressions as shown below, and combine like terms to express the final result:

f(x)=7x^3-10x^2-5\ng(x)=2x^3+7x^2-9\nf(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\nf(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\nf(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\nf(x)-g(x)=5x^3-17x^2+4

Write the equation in slope-intercept form. -24x+8y=16

Answers

-24x+8y=16

Add 24x to both sides:

-24x+8y+24 = 16+24x

8y =16+24x

Divide both sides by 8 :

(8y)/(8) = (16+24x)/(8)

y = 3x + 2

A newborn giraffe weighs about 65 kilograms how much does it weigh in grams

Answers

The newborn giraffe's weight is 65,000 grams

Further Explanation

Given:

The newborn giraffe weight is 65 kilograms (kg).

How much does it weigh in grams (g)?

We know that, 1 kilogram = 1000 gram.

In order to convert kilograms to grams, we just do multiplying

=\boxed {65 kg *1000g\ }\n =\boxed {65000g\ }

To simplify, there is an order system to convert:

  • write the conversion in fraction
  • multiply
  • cancel any unit that are both top and bottom

\boxed {(1000g)/( 1kg) = (x g)/(65 kg)\ }\n \boxed {x =(1000g *\ 65 kg)/(1 kg)\ }\n \boxed {x = 65000g\ }

We cancel the kilogram (kg) because it is both in top and the bottom.

Kilogram (kg) and gram (g) are the most common unit of mass in metric system of measurement.

Write 7/10 as a sum of fractions two different ways.

Answers

(1)/(10) + (6)/(10) = (7)/(10) \n \n (2)/(10) + (5)/(10) = (7)/(10) \n \n (3)/(10) + (4)/(10) = (7)/(10)


some fun

(7)/(10) = (14)/(20) \n \n (9)/(20) + (5)/(20) (14)/(20) = (7)/(10)

(7)/(10) = (21)/(30) \n \n (8)/(30) + (13)/(30) = (21)/(30) = (7)/(30)
7/10 is equal to 3/10 plus 4/10

And

7/10 is equal to 5/10 plus 2/10,
