Is x - 4 = 2 an equation or an expression? Explain.

1 answer:

6 0

Answer: equation

Reasoning: So an easy way to remember this is, an equation has an equals sign. So remember equal sounds like equation so that’s a way to know. And an expression doesn’t have an equals sign.

For each answer, we can plug in the given points:

A) is technically the same as B), but B) expresses correct function notation.

B) 5 = 5(1) ⇒ 5 = 5
25 = 5(2) ⇒ 25 ≠ 10
B) is incorrect.

C) I'm not sure what you mean y=5^5=x, but I'm going to use $y=5^{x}$ because it's close to what you wrote:
$5=5^{1} =\ \textgreater \ 5=5 \\ 25=5^{2} =\ \textgreater \ 25=25 \\ 125=5^{3} =\ \textgreater \ 125 = 125 \\ 625=5^{4}=\ \textgreater \ 625=625 \\ 3125=5^{5}=\ \textgreater \ 3125=3125$
The function $y=5^{x}$ works for the points given.

D) 5 = 1 + 5 ⇒ 5 ≠ 6
D) is not correct.

Please check your functions; I'm not sure that C) is a function. In any case, the answer is C) because all the other answers are wrong.
