Answer:
The sum of 2 and the quotient of 3 and y
Step-by-step explanation:
The expression 2 + 3/y without any parentheses is evaluated as ...
2 + (3/y)
which is a sum. The first contributor to the sum is 2, and the second contributor is the quotient of 3 and y. (Usually, "the quotient of "a" and "b" means "a/b".)
Hence the answer shown above is a good description of the expression.
Answer:
The distributive property also can be used to simplify algebraic equations by eliminating the parenthetical portion of the equation. Take for instance the equation a(b + c), which also can be written as (ab) + (ac) because the distributive property dictates that a, which is outside the parenthetical, must be multiplied by both b and c.
Step-by-step explanation:
The word "associative" comes from "associate" or "group"; the Associative Property is the rule that refers to grouping. For addition, the rule is "a + (b + c) = (a + b) + c"; in numbers, this means 2 + (3 + 4) = (2 + 3) + 4. For multiplication, the rule is "a(bc) = (ab)c"; in numbers, this means 2(3×4) = (2×3)4. Any time they refer to the Associative Property, they want you to regroup things; any time a computation depends on things being regrouped, they want you to say that the computation uses the Associative Property.
The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2. Any time they refer to the Commutative Property, they want you to move stuff around; any time a computation depends on moving stuff around, they want you to say that the computation uses the Commutative Property.
Answer:1st one 93 2nd 77 and 3rd 369
Step-by-step explanation:
The equation has 0 real solutions.
If an equation has a negative discriminant, than there are no real solutions. We know this because the quadratic formula requires you to take the square root of the discriminant and therefore you would have all imaginary numbers.
