Answer: 0 = 3
Step-by-step explanation: If y = 7 - 3x, we can plug that in for y in the equation 3x + y = 10 by writing it as 3x + 7 - 3x = 10.
- 7 - 7
--------------------------
3x - 3x = 3
0 = 3
Divide 45 by 5
9
Now multiply 20 by 9
180
Your answer should be 180.
The median is where you add all the numbers up and divide them by how many total numbers there were
You should get: y=-x+1. The slope is -1, which is implied because the you don't need the one in front of the x.
its the third answer bro i did the equation.
