Which ordered pair is a solution of the equation? y=-2x+5y=−2x+5 (Choice A) A Only (2,-9)(2,−9) (Choice B) B Only (-2,9)(−2,9) (Choice C) C Both (2,-9)(2,−9) and (-2,9)(−2,9) (Choice D) D Neither
Answers
Answer:
Choice B: Only (-2, 9)
Step-by-step explanation:
Of the two choices, only the point (-2, 9) satisfies the equation:
... y = -2x +5
... 9 = -2(-2) +5 = 4 +5 = 9
Answer:
The correct answer is B. Only (-2,9) is a solution of the equation.
Step-by-step explanation:
To figure out if an ordered pair is a solution to an equation, you could perform a test.
Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.
We have the equation
and two different ordered pairs (2, -9) and (-2, 9).
We use the x-value in the first ordered pair, x = 2, and we plug it into the equation.
If we compare with the ordered pair (2, -9), y must be equal to -9, but when we plugged x = 2 into the equation, we obtained that y = 1, so this is not a solution.
Using the x-value of the second ordered pair, x = -2, we get
Because we obtained y = 9, when we plugged x = -2, the ordered pair (-2, 9) is a solution of the equation.
The correct answer is B. Only (-2,9) is a solution of the equation.

What are the factors of the expression?
Answers
Answer:
“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
Step-by-step explanation:
Let us breakdown and translate the word expression into an algebraic expression.
The sum of 3c and 8 is algebraically represented as:
⇒ 3c + 8
Thus, “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:
⇒ (6.2) (3c + 8)
We know that the numbers that we multiply are the factors of the product.
Here, (6.2) and (3c+8) are the factors of the expression.
