You = her*1.1

her = you/1.1 = you*0.9090...

her = you - you*(1 - 0.9090...) = you - you*0.0909...

--> 9.09% younger

x = 9.09

Mid point formula

(x1 + x2) , (y1+y2)
--------- --------
2 2
Thus for x it would be (6+(-2)) /2 or 4/2 or 2.
For y (-4 + 4) / 2 or 0 / 2 or 0.
Mid point is (2,0)

Solve this quadratic equation using the quadratic formula. 2x 2 - 10x + 7 = 0

madam [21]

Answer:

$x_1=4.158$

$x_2=0.8416$

Step-by-step explanation:

For an equation of the form $ax^2 +bx +c$

The quadratic formula is

$\frac{-b\±\sqrt{b^2 -4ac}}{2a}$

In this case the equation is:

$2x^2 - 10x + 7 = 0$

Then

$a= 2\\b= -10\\c= 7$

Therefore, using the quadratic formula we have:

$x=\frac{-(-10)\±\sqrt{(-10)^2 -4(2(7)}}{2(2)}$

$x=\frac{5\±\sqrt{11}}{2}$

$x_1=4.158$

$x_2=0.8416$
