Let H (6, 7) be (x₁, y₁) and I (-7, -6) be (x₂, y₂)
Mid point =
![[ \frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%5D%20%20)
Mid point = [
![[ \frac{6+-7}{2}, \frac{7+-6}{2}]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B6%2B-7%7D%7B2%7D%2C%20%20%5Cfrac%7B7%2B-6%7D%7B2%7D%5D%20%20)
Mid point =
![[ \frac{-1}{2}, \frac{1}{2}]](https://tex.z-dn.net/?f=%5B%20%5Cfrac%7B-1%7D%7B2%7D%2C%20%20%5Cfrac%7B1%7D%7B2%7D%5D%20%20)
Santiago is not correct, the mid point is (-0.5, 0.5)
Ok
so paid 16
20% off
original-20%=16
that means the shorts were 100-20=80% of the original cost
percent means parts out of 100
80%=80/100=0.80
16=0.8 of ogirinal cost
'of' means mutpliy
16=0.8 times original
divide both sides by 0.8
16/0.8=ogirinal
20==originall
$20=original price
This is saying that -3 is the result of a number "p" plus 10...therefore the equation is p+10=-3
Answer:
<u>(3); (-1/2); (-4)</u>
Step-by-step explanation:
First, you should convert the equation into cubic form.
r(x)=(x^2+x−12)(2x+1)
<u>2x^3 +3
x^2
− 23x− 12=0</u>
Next, use the rational roots test to find the first root.
<u>(-1/2) </u>
Using the factor theorem you can find the other roots.
<u>(3)</u> <u>(-4)</u>
1) 4x+6= 10; x=1
2) c + 5= 15; c=10
3) 2 - a= 18; a= -16
4) -8x=16; x= -2
5) a+6= 12; a=6
6) 3+b= 18; b=6
7) -5 - x= 19; x= -24
8) 7+4b= 34; b= 6.75
