Answer:
Estimation is a mental process of coming up with an answer that is relatively close, to allow decisions to be made. The types of estimation are quantity, computation and measurement.
An estimation strategy is simply coming up with a good estimate based on evidence and already known facts. Coming to a conclusion as close to the real answer as you can. It can also be called an educated guess.
Answer:
x=10, y=-1
(10,-1)
Step-by-step explanation:
x-y=11
2x+y=19
Add these two equations together to eliminate y
x-y=11
2x+y=19
--------------
3x = 30
Divide each side by 3
3x/3 = 30/3
x = 10
Now we need to find y
2x+y = 19
2(10) +y = 19
20+y =19
Subtract 20 from each side
20-20 +y = 19-20
<h2>y= -1
</h2>
Answer:
Polynomial=4x^3+2x^4+15x-5
in standard form:2x^4+4x^3+15x-5
Step-by-step explanation:
The <em>correct answer</em> is:
Irrational.
Explanation:
We are adding a rational number, 4.2, and an irrational number, √2.
Adding an irrational number to anything makes the sum irrational.
The only way to get a rational number from an irrational number is to multiply or divide. There is no way to rationalize an irrational number by adding or subtracting.
