The answer is
the vector PQ has (4-1, 8-2) as components, so it is vecPQ= (3, 6)
using the definition
the distance PQ= sqrt ( 3²+6²)= sqrt(9+36)=sqrt(45)
2x + y = 8
3x - y = 17
---------------add
5x = 25
x = 25/5
x = 5
2x + y = 8
2(5) + y = 8
10 + y = 8
y = 8 - 10
y = -2
solution is (5,-2).....this is consistent and independent because it has one solution
Answer:
a=-15
Step-by-step explanation:
(1/3)a=-5
a=-5/(1/3)
a=(-5/1)(3/1)
a=-15/1
a=-15
Part a: f(0) = 0
There isn't much explanation for part a: just plug it in.
Part b: Look at the attached image.
I hope this helps.
18.88 divided by 1.6 is 11.8.
