To divide fractions, we do Keep, Change, Flip. Keep means that we keep the first fraction the same ( which is 8/1). Then for Change, we change the division sign to a multiplication sign. After that we Flip the second fraction itś reciprocal (or multiplicative inverse).
So your equation would be:

8/1 x 3/1 which equals 24

Answer:

(x + 3)^2 + (y- 2)^2 = 4

Step-by-step explanation:

A circle which has center at point(a,b) on coordinate plane and its radius is r, then its equation is represented by

(x-a)^2 + (y-b)^2 = r^2

______________________________________

In the problem

we have

center as (-3,2) while radius is 2 units.

Thus, it equation can be written based on above discussion as

a = -3,  b = 2 r =2

(x-a)^2 + (y-b)^2 = r^2 \n(x-(-3))^2 + (y- 2)^2 = 2^2\n(x + 3)^2 + (y- 2)^2 = 4

thus, correct choice is option third.

Hence the answer is F
f(-3)=-8\cdot(-3)^2=-8\cdot9=-72

How can you write 31/6 as a mixed number

Answers

The answer is 5 1/6

To check if it is correct, do this:

            5 * 6 + 1


      = 31/6


  *tada*
31/6 

6 goes into 31, 5 times

5*6 = 30

31 - 30 = 1

Answer: 5 and 1/6

Simplify

(2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)

Answers

Answer:

3x^2 - 9x + 8

Step-by-step explanation:

To simplify:

  • Distribute the -1 into the second term.
  • Collect and combine like-terms (terms with the same variables or powers)

The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)

After distributing the -1, the equation becomes:

  • (2x^2 - 5x + 3) + (x^2 - 4x + 5)

The like-terms are:

  • 2x^2 and x^2
  • -5x and -4x
  • 3 and 5

Combine the like-terms:

  • 2x^2 + x^2 = 3x^2
  • -5x - 4x = -9x
  • 3 + 5 = 8

Substitute the simplified like-terms into the expression, in descending order:

  • 3x^2 - 9x + 8
