To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,
5x = 10
Let's say you got an answer of x = 4. Plug it back into the equation
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong.
The correct answer is x = 2
Answer:
95/21
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-97)/(-11-10)
m=-95/-21
m=95/21
Answer: - 4
because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees
=> the temperature at noon was -12 + 16 = 4 (degrees)
At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:
4 - 8 = -4 (degrees)
Step-by-step explanation:
Answer:8000 i think
Step-by-step explanation:
=20 to the power of nine-20 to the power of four=20 to the power of three.
20 to the power of three is 8000.
Hope this helps.
