Isaiah has a points card for a movie theater. • He receives 75 rewards points just for signing up.
• He earns 6.5 points for each visit to the movie theater.
• He needs at least 140 points for a free movie ticket.
Write and solve an inequality which can be used to determine x, the number of visits
Isaiah can make to earn his first free movie ticket.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

i dont understand the question? ?

step-by-step explanation:

what? that isnt a question

step-by-step explanation:

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
