Which of the following are true statements about the expression 7+(−7)?Choose 2 answers:(A) The expression describes the number that is 7 to the left of 7 on the number line.(B) The expression describes the number that is 7 to the right of 7 on the number line.(C) The expression equals 0 .(D) The expression equals 14.
Q. Which of the following are true statements about the expression 7+(−7)?Choose 2 answers:(A) The expression describes the number that is 7 to the left of 7 on the number line.(B) The expression describes the number that is 7 to the right of 7 on the number line.(C) The expression equals 0 .(D) The expression equals 14.
Evaluate Expression: We need to evaluate the expression 7+(−7) to understand its value on the number line.Calculation: 7+(−7)=0
Analyzing Statements: Now let's analyze the statements given:A) The expression describes the number that is 7 to the left of 7 on the number line.This statement is incorrect because adding −7 to 7 would result in a value of 0, which is not 7 to the left of 7.
Statement A: B) The expression describes the number that is 7 to the right of 7 on the number line.This statement is incorrect because adding −7 to 7 would result in a value of 0, which is not 7 to the right of 7.
Statement B: C) The expression equals 0. This statement is correct because the calculation we performed in the first step confirms that 7+(−7) equals 0.
Statement C: D) The expression equals 14. This statement is incorrect because the calculation we performed in the first step confirms that 7+(−7) does not equal 14.
