Taylor rates expression with five terms. 05 terms are like terms. How many terms are in equipment expression with the least number of terms? Explain.

i dont know this one sdfghjasdfghj

Step-by-step explanation:

A) Only the first is true: we can solve the equation for y:

So, if you fix any value for x, you can choose y=7-2x and the equation will be true. The other claim is not true: the value for x that solves the equation depends on the value of y, so we can't hope to find a "universal" x-value such that the equation is true for all y-values.

B) Both are trivially true, because the equation is an identity: addition is commutative.

C) Only the first is true: we have

So, whatever value we fix for x, we can choose y=x and the equation becomes

which is clearly true. The other claim is not true: the value for x that solves the equation depends on the value of y, so we can't hope to find a "universal" x-value such that the equation is true for all y-values.

D) Both claims are false: claim number 1 is false because the only solution to the equation is x=5, so you can't choose any value for x and expect to find a solution by choosing an appropriate value for y. Claim number 2 is false because, even if we choose x=5, the equation is true for all the possible values of y, except y=1, which is an excluded value for this expression

E) Both claims are false: and are positive numbers, because their are squares, and their sum can't be -1.
