What does this answer mean? Like, what is a “solution set” and an “identity?” I know what multiplicative (x1) and additive identities (+0) are, but what is this? What is true for any value of x? That 4 = 4? And if so, what does that even mean? Solve 2(x + 1) - (x - 2) = x + 4 for x.
SOLUTION
2(x + 1) - (x - 2) = x + 4
2x + 2 - x + 2 = x + 4
x + 4 = x + 4
4 = 4

“This is true for any value of x. The solution set is all real numbers. This equation is an example of identity.”

ian gone lie this got me confused

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a
