ANSWER
EXPLANATION
The given vector is v = −14.5i + 2.5 j.
The magnitude of this vector is
The unit vector in the direction of this vector is
We can multiply the number of parts Marsha has finished by the miles of each part:
5 × 1/10
= 5/10
=1/2
Therefore, she raced 1/2 miles.

Answer:
Step-by-step explanation:
y = 3x + 2
6x – 2y = 10
Ryan’s answer:
I solved by adding the equations. The solution is .
y = 3x + 2 → 3x + y = 2
6x – 2y = 10 → 3x – y = 5
6x = 7
x =
6x – 2y = 10 → 6 – 2y = 10
7 – 2y = 10
–2y = –3
y = -
Jesse’s answer:
I used matrices. The solution is .
Mark’s answer:
I graphed the equations. The lines are parallel and do not intersect, so there is no solution.
First make x the subject of f(x) = 2x - 10:-
2x = f(x) + 10
x = 1/2 f(x) + 5
mow replace x by hx) and f(x) by x:-
h(x )= 1/2 x + 5
