Answer:
3xy - xz, or x(3y - z)
Step-by-step explanation:
2x(y-z)+x(y+z) becomes
2xy - 2xz)+ xy + xz)
combining the xy terms, we get 3xy;
combining the xz terms, we get -xz
Thus, the complete simplified expression is 3xy - xz, or x(3y - z)
Answer:
m= <u>y2 - y1</u>
x2 - x1
m= <u>-7 + 3</u> ( I have + 3 and 4 because when negative cancel negative, it is
-2 + 4 positive)
= <u>-4</u> = 2
-2
Step-by-step explanation:
- write down the formula for finding slope.
- replace the y's and x's with the values.
- add everything together
- divide
