909()
Answer:
No
Step-by-step explanation:
Assuming that you put the wrong sign for the second equation if you plug (2,7) into the two equations it only works for one equation.
Answer:
C. Subtract 4 from both sides.
Step-by-step explanation:
You need the equation in the form x² + ax + b = 0 to then either try factoring or use the quadratic formula.
In order to achieve that, you need to first:
Subtract 4 from both sides.
Answer:
b we now know that a = 35° and, since the sum of the triangles equal 180° we can find angle b. Angle c and the 95° angle are supplementary; they add up to 180°.
Step-by-step explanation:
The sets for each of the given numbers are:
- 6426: Real, rational, integer and whole.
- √7: Real and irrational.
- 2π: Real and irrational.
- 4.0: Real, rational, integer, whole.
- √(25/36): Real and rational.
- -√16: Real, rational, and integer.
- -35: Real, rational, and integer.
- -31.8: Real and rational.
<h3>
To which set each number belong?</h3>
Here we need to identify 3 sets
- Rational numbers: all of these that can be written as a quotient of two integers.
- Irrational numbers: all of these that can't be written as a quotient of two integers.
- Integers: Any number that can be got by adding or subtracting ones.
- Whole numbers: All the integers equal or larger than 0.
- Real number: any of the above is a real number.
The first number is:
6426
It can be rewriten to:
6426/1
So this is: Real, rational, integer, and whole number.
Second number:
√7
This is a real and irrational number (square roots of non-square numbers are irrational numbers).
Third number:
2π
This is a real and irrational number, because π is irrational.
Fourth number:
4.0
This is: Real, rational, whole, and integer.
Fifth number:
√(25/36)
We can simplify that to:
√(25/36) = 5/6
So this is a real and rational number.
Sixth number:
-√16 = -4
That is a: Real, rational, and integer number
Seventh number:
-35
Same as the above one, real, rational, and integer.
Eight number:
-31.8
It can be written as:
-31.8 = -318/10
So this is real and rational number.
