U=9i-9j and v=-8i 4j find u-v

Mathematics
1 answer:
Jlenok [28]3 years ago
8 0

Answer:

u - v = 17i  -13j

Step-by-step explanation:

Rewrite u=9i-9j and v=-8i 4j  vertically:

u=9i-9j

v=-8i + 4j

We want to subtract the second equation from the first:

u=9i-9j

v=-8i + 4j

-----------

u - v = 17i  -13j

Note:  I assumed that a " + " sign precedes 4j in the second equation.

vovangra [49]

Answer: 8200 miles

Step-by-step explanation:

Based on the question, since she wants to go for five round trips, her first round trip is fixed at 3400 and she will have 4 more additional trips. This can them be calculated as:

= 3400 + 1200x

x = additional trips = 4

We then put the value of x into the equation

= 3400 + 1200x

= 3400 + 1200(4)

= 3400 + 4800

= 8200

She'll have 8200 mile after 5 round trips
