First you subtract
y2-y1
x2-x1
(-3,6) -9-6=-15
(5,-9)5-(-3)=8
if i can be simplified then simplify it
HOPE I HELPED!
50 = x^2 - 9x + 14
x^2 - 9x + 14 - 50 = 0
x^2 - 9x - 36 = 0
(x - 12)(x + 3) = 0
x - 12 = 0
x = 12 <==
x + 3 = 0
x = -3......not this one
The Pythagorean theorem states:
where a and b are the lengths of the legs and c is the length of the hypotenuse of a right triangle.
Substituting with a = 80 and b = 39, we get:
![\begin{gathered} c^2=80^2+39^2 \\ c^2=6400+1521 \\ c^2=7921 \\ c=\sqrt[]{7921} \\ c=89 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20c%5E2%3D80%5E2%2B39%5E2%20%5C%5C%20c%5E2%3D6400%2B1521%20%5C%5C%20c%5E2%3D7921%20%5C%5C%20c%3D%5Csqrt%5B%5D%7B7921%7D%20%5C%5C%20c%3D89%20%5Cend%7Bgathered%7D)
Answer:
2 11/12
Step-by-step explanation:
total amount fred used = 1/3 x 7 = 7/3
total amount Janice used = 1/4 x 7 = 7/4
total amount used =
7/3 + 7/4
(28 + 21) / 12 = 49 / 12 = 4 1/12
Amount left = 7 - 4 1/12 = 2 11/12
