The answer is D) y = -1/3x
This is because from point to point, there is a negative decrease of 1 vertical and 3 horizontal.
It is equal to 7a
we can show that this is true because of distributive property
ab+ac=a(b+c)
2a+5a=a(2+5)=a(7)=7a
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
