Answer:2(xy-7)= -20
Step-by-step explanation:
Plug in -1 for x and 3 for 3, as the question says that x and y represent those values.
2(xy-7) = ?
2((-1)(3) - 7) = ?
2(-3-7)=?
2(-10)
-20
2(xy - 7) = -20
1. Add all of the numbers together
2. Divide the answer by how many different numbers there are (so 10)
The mean to the nearest tenth is
356.8
