Answer:
Step-by-step explanation:
- -2.8f + 0.9f - 12 - 4 =
- (-2.8 + 0.9)f - (12 + 4) =
- -1.9f - 16
Volume = 3.14xradius squared x height so it’s 3.14 x 6x6 x8 = 904.32
Answer:2
Step-by-step explanation:
Answer:
the solution is (-4, -3)
Step-by-step explanation:
Multiply the first equation by 2. This produces 4x + 2y = -14.
Now combine this result with the second equation:
4x + 2y = -14
-3x - 2y = 10
------------------
x = -4
Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.
Then x = -3/2, and the solution is (-4, -3)
