Solve 2x ≤ 30. Round to the nearest ten-thousandth.
a. {x | x 30.7386)
b. {x|x ≤ 1.9985)
C. {x| ≤ 1.8000)
d. {X/x ≤ 4.9069}

Um i think it is B and i'm gonna be honest i'm not as good with math as i am in reading.

Step-by-step explanation:

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
