Answer:

B = (3, 5)

Step-by-step explanation:

Point A is at (-7,5) and point C is at (5,-1). Find the coordinates of point B on AC such that AB is 5 times longer than BC. Then, B split AC in a 5:1 ratio.

rise = yC - yA = -1 - 5 = -6

run = xC - xA = 5 - (-7) = 12

c = 5/(5+1) = 5/6

B = (xA + c*run, yA + c*rise)

B = (-7 + 5/6*12, 5 + 5/6*-6)

B = (3, 5)

Answer: (3,0)

Step-by-step explanation: Point A is at (-7,5) and C is at (5-1). The horizontal displacement of AC is : 5-(-7)=12 If the horizontal displacement from A to C is 12 then horizontal displacement from A to B is 10. So point B is 10 units to the right of point A. The vertical displacement from A to C is -6, then the vertical displacement from A to B is -5. So point B is 5 units down from point A. Point A was at (-7,5) and point B is 10 units to the right and 5 units down from point A. B= (-7+10,5-5) = (3,0). The coordinates of B are (3,0).

Q1. The answer is $4y+ \frac{1}{2y-1}$

$\frac{8y^{2}-4y+1 }{2y-1} = \frac{4y*2y-4y+1}{2y-1} = \frac{4y(2y-1)+1}{2y-1} = \frac{4y(2y-1)}{2y-1}+ \frac{1}{2y-1} =4y+ \frac{1}{2y-1}$

 $\frac{6 x^{3} +11 x^{2} -4x-4}{3x-2} = \frac{3x*2 x^{2}-2 x^{2} *2+15 x^{2} -4x-4 }{3x-2} = \frac{2 x^{2} (3x-2)+15 x^{2} -4x-4}{3x-2}= \\ \\ = \frac{2 x^{2} (3x-2)}{3x-2} + \frac{15 x^{2} -4x-4}{3x-2} =2 x^{2} +\frac{15 x^{2} -4x-4}{3x-2}=2 x^{2} + \frac{15 x^{2} -10x+6x-4}{3x-2}= \\ \\ =2 x^{2} + \frac{5x*3x-5x*2+6x-4}{3x-2} =2 x^{2} + \frac{5x(3x-2)+3x*2-2*2}{3x-2} = \\ \\ =2 x^{2} + \frac{5x(3x-2)}{3x-2} + \frac{3x*2-2*2}{3x-2} =2 x^{2} +5x+ \frac{2(3x-2)}{3x-2} =2 x^{2} +5x+2$


Q4. The answer is 2x + 7

 $\frac{6 x^{2} +11x-35}{3x-5} = \frac{6 x^{2} -10x+21x-35 }{3x-5} = \frac{3 x *2x-5*2x+7*3x-7*5 }{3x-5} = \\ \\ = \frac{2x(3x-5)+7(3x-5)}{3x-5}= = \frac{(3x-5)(2x+7)}{3x-5} =2x+7$


Q5. The answer is $x+1- \frac{3}{x-1}$ 

 $\frac{ x^{2} -4}{x-1} = \frac{ x^{2} -x+x-1-3 }{x-1} = \frac{x*x-x+x-1-3}{x-1} = \frac{x(x-1)+(x-1)-3}{x-1} = \\ \\ \frac{(x+1)(x-1)-3}{x-1} = \frac{(x+1)(x-1)}{x-1} -\frac{3}{x-1} =x+1- \frac{3}{x-1}$

How can i factor this? x^(2n)-2x^(n)+1

Tasya [4]

You can make it easier by replacing x^n with another variable, factoring, then putting x^n back in the end.

Using exponent and algebra rules, rewrite x^2n - 2x^n + 1 as
(x^n)^2 - (2 x x^2) + 1

Then, let x^n = m.

m^2 - 2m + 1

Now factor that: (m - 1)^2

And now put x^n back: (x^n - 1)^2

PLEASE HELP A rectangular region is removed from another rectangular region to create the shaded region shown below. Find the ar

Mars2501 [29]

<h3>Answer: shaded region has area 107 square feet</h3>

================================================

Work Shown:

A = area of larger rectangle

A = length*width = 9*15 = 135 square feet

B = area of smaller rectangle

B = length*width = 7*4 = 28 square feet

C = area of shaded region

C = difference in areas of A and B

C = A - B = 135 - 28 = 107 square feet
