Which of the following statements are true? select all that apply for all real numbers a and b, a+b=b+a for all real numbers a and b, ab=ba for all real numbers a and b, a-b=b-a for all real numbers a and b, a/b=b/a for all real numbers a, b, and c, (a+b)+c=a+(b+c) for all real numbers a, b, and c, (a-b)-c=a-(b-c) for all real numbers a, b, and c, a(b+c)=ab+ac for any provided!

Hello there!

if a and b are real numbers:

1)  For all real numbers a and b, a+b=b+a: This is true, it is called the commutative property of the addition.

2) For all real numbers a and b, ab=ba: This is true, it is called the commutative property of the multiplication.

3) For all real numbers a and b, a-b=b-a: This is false, a counter example is if we took a = 1 and b = 0; then a -b = 1, and b - a = -1.

4) For all real numbers a and b, a/b=b/a: This is false, if we took a= 4 and b = 2, then a/b = 4/2 = 2, and b/a = 2/4 = 1/2, which are different.

5) For all real numbers a,b, and c, (a+b)+c=a+(b+c): This is true, it is called the distributive property of the addition.

6)  For all real numbers a,b, and c, (a-b)-c=a-(b-c): this is false; in the left side of the equation we have (a -b) -c, that if we remove the parenthesis is equal to a -b -c

in the right side we have a -( b - c) if we remove the parenthesis and distribute the minus sign, we get: a -b + c

7) For all real numbers a,b, and c, a(b+c)=ab+ac: This is true, it is called the distributive property of the multiplication.

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
