Zack went to the movie theater. His ticket cost $5.75 and each candy he bought cost $2.25. How many candies did Zack buy if his total was $21.50? Write a linear equation to represent this situation and solve

answer: 12

step-by-step explanation:

because yes

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

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

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
