Step-by-step explanation:
F(x) = 1/9 - 9
= (1-81)/9
=-80/9

Plzz mark it as a brilliant answer
Let z be any number (like x would be)
if we set z equal to 2x-6y, then we get z = 2x-6y
The system
2x-6y = 8
2x-6 = 3
turns into this new system
z = 8
z = 3
but z is a single number. It can't be both 8 and 3 at the same time. So there are no solutions
You already have the base area, so to work out the volume, you just multiply 140 by 6.
Therefore, the answer is B. 840 ft³ :)
Answer:
40
Step-by-step explanation:
Any solution x will mod 23 will also have x+23n as a solution, for some integer n. Since 900/23 = 39 3/23, we know there are 39 or 40 three-digit integers of this form.
As it happens, 100 is the smallest 3-digit solution. So, there are 40 three-digit numbers that are of the form 100 +23n, hence 40 solutions to the equation.
_____
The equation reduces, mod 23, to ...
10x = 11
Its solutions are x = 23n +8.
3/10 times 2/3 3 times 2 is 5 and 10 times 3 is 30 5/30 a
