Step-by-step explanation:

midpoint of AC=(x¹+x²/2,y¹+y²/2)

=(-12+6/2,-8+14/2)

=(-6/2, 6/2)

=(-3,3)

What is the simplified form of each expression? 7x^–8 × 6x^3

klio [65]

7*6*x^-8*x^3
42x^-8+3 (bases same powers add)
42x^-5
1/42x^5
so the simplified form of 7x^-8*6x^3 is=1/42x^5

Wrich expreson is equivalent to 4(3-6).

Korvikt [17]

You haven’t provided any option, however I think I can still help.

You can solve 4(3-6). You first deal with he parenthesis, and get 4(-3). This means that your expression is equivalent to -12.

Hope this helps :)

Find the distance between the two points and simplest rational form (3,-4) (6,-7))

pychu [463]

Answer:

$D = 3\sqrt{2}$

Step-by-step explanation:

Given

$(x_1,y_1) = (3,-4)$

$(x_2,y_2) = (6,-7)$

Required

Determine the distance between the two points

Distance (D) is calculated as:

$D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Substitute values for x's and y's

$D = \sqrt{(6 - 3)^2 + (-7 - (-4))^2}$

$D = \sqrt{(6 - 3)^2 + (-7 +4)^2}$

$D = \sqrt{(3)^2 + (-3)^2}$

$D = \sqrt{9+9}$

$D = \sqrt{18}$

Express as 9 * 2

$D = \sqrt{9*2}$

Split:

$D = \sqrt{9}*\sqrt{2}$

$D = 3*\sqrt{2}$

$D = 3\sqrt{2}$

Anna had $54 in her purse. She bought a book for $26.34 and a book marker for $1.27. Anna’s mom then gave her $10 for completing

jekas [21]

Answer:

Anna has $36.39 dollars.

Step-by-step explanation:

All we have to do is subtract

54 - (26.34 + 1.27) =

54 - 27.61 =

36.39

So, the answer is 36.39

Hope this helps! :)
