Answer: x= 9.2
Scale Factor is 2.5
Step-by-step explanation:
1. Divide 17.5 by 7 to find scale factor
2. So 17.5/7=2.5
3. Divide 23 by 2.5 to find x
4. So 23/2.5=9.2
(a) i. See comment...
(a) ii. We have

and

(b) We can parameterize the line segment from P to Q by the vector function

with
. The point R is located 1/3 of the way along this line segment, i.e. at
, so its position vector is

and hence its coordinates are
.
√49y^14
separate the function
V49 x Vy^14
7 x y^7 --- just divide the exponent in half
7y^7
264 because you can do 8 divided by 6 and get 1.3 repeating, than you would do 198 times 1.333333333333 and you get 264
