Answer: Yes, the set of real numbers is closed under addition.
Explanation:
Let x and y be two real numbers. Their sum x+y is some other real number. This is what it means when we say the set of real numbers is closed under addition. Taking any two numbers and adding them will get us some other real number.
There is no way to have x+y be nonreal while x,y are both real.
4x+11 is The answer
-2x-(-6x) two negatives make a positive so -2x-(-6x) is now -2x+6x
-2x+6x=4x
4-(-7) again two negatives make a positive so 4-(-7)
Is now 4+7
4+7=11

Answer:
The standard general equation for a straight line is:
y = mx + C. You said the slope of line is 2/3. m is always the slope in this context. So with the numerical value slope we have the line
Y = 2/3 X + C. You also said the line passes through the point (1, -4) that is the X value is 1 and the y value is -4. Substitute these value into the linear equation to find C, as follows
-4 = 2/3 + c. and so C = - 4 - 2/3 = -14/3 and so the equation of line is :
y = 2x/3 + 14/3 or if you like 3y = 2x + 14
It is important to remember that the convention of the bracketted numbers e.g. (1,-4) or ( 1, -4, z), say is that the first number in the brackets indicates the X value, the second the y value and the third, the z value in the case of 3 D coordinates.
170x59425=10,102,250
Which is approximately 10 million, so your answer is C

Four switches may be modeles as:
_ _ _ _, where you can put one of two marks (off or on) on any _.
So, the number of different ways will be 2 * 2 * 2 * 2 = 16
Answer: 16 possible settings.
