1 answer:

7 0

Well you are going to need a rule or formula like x + 6 or 3 (x) + 2

Example:

Input x + 6 Output
2 2+ 6 8
4 4+6 10
6 6+6 12

Hope this helps sorry if it doesn’t

The difference between two numbers is 9.

laiz [17]

Answer:

first number=15 second number=6

Step-by-step explanation:

lets take the first and second numbers as "a" and "b"

a-b=9

a+2b=27 (solve these equations simultaneously)

eliminating a

-3b= -18

b= 6

then substitute in the first equation

a-6=9

a=9+6

a=15

I really hope you know how to solve equations simultaneously

hope this helped

Solve i + j + t (3i - j) = -i + s (j)<br> In the context of Vector Equations of a Line

Oksana_A [137]

Answer:

r = i + j + (-2/3)(3i - j)

Step-by-step explanation:

Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant

if a = i + j ; b = t(3i - j) and r = -i +s(j)

for this to be true all the vector components must be equal

summing i 's

i + 3ti = -i; then t = -2/3

j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3

so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j
