Answer
Haven't done this for a bit but I think it's 19
Step-by-step explanation:
2 * 2 * 2 = 8
27 - 8 = 19
Answer:
t=(2.5,0)
Step-by-step explanation:
Given that
![t=\frac{1}{2} u+v](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1%7D%7B2%7D%20u%2Bv)
and
u=(-1,4)
v=(3,-2)
Then,substitute value of u and v in the equation
![t=\frac{1}{2} (-1)+3=-\frac{1}{2}+ (3)=2.5\\\\\\\\t=\frac{1}{2} (4)+-2=2+-2=0\\\\\\t=(2.5,0)](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B1%7D%7B2%7D%20%28-1%29%2B3%3D-%5Cfrac%7B1%7D%7B2%7D%2B%20%283%29%3D2.5%5C%5C%5C%5C%5C%5C%5C%5Ct%3D%5Cfrac%7B1%7D%7B2%7D%20%284%29%2B-2%3D2%2B-2%3D0%5C%5C%5C%5C%5C%5Ct%3D%282.5%2C0%29)
Answer:
t = ![\frac{2r}{r+1}](https://tex.z-dn.net/?f=%5Cfrac%7B2r%7D%7Br%2B1%7D)
Step-by-step explanation:
Isolate the term with t by adding s to both sides
= rs + s = s(r + 1) ← common factor of s
multiply both sides by t to eliminate the fraction
ts(r + 1) = 2rs ( divide both sides by s(r + 1)
t =
← cancel s on numerator/denominator
t = ![\frac{2r}{r+1}](https://tex.z-dn.net/?f=%5Cfrac%7B2r%7D%7Br%2B1%7D)
