Find the midpoint between (4,-1) and (3,2)

zepelin [54]

Midpoint has form of,

$M(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

We can insert the data,

$M(\dfrac{4+3}{2},\dfrac{-1+2}{2})$

Which simplifies to,

$\boxed{M(3.5, 0.5)}$

Hope this helps.

Which of the following represents the factorization of the binomial below ? x^2 - 144

Dima020 [189]

It factors to (x+12)(x-12)

This is the same as (x-12)(x+12) as we can multiply two expressions in any order we want. This is like saying 7*5 is the same as 5*7

I used the difference of squares rule to factor x^2 - 144. It might help to write x^2 - 144 as x^2 - 12^2, then compare it to a^2 - b^2 = (a-b)(a+b)

80% of Original Shoe price = $82

82 / 0.8 = 102.5

102.5-20=82.5
