Alexandria ate at most two hundred fifty calories more than twice the number of calories her infant sister ate. alexandria ate eighteen hundred calories. if i represents the number of calories eaten by the infant, which inequality represents the situation?

Step-by-step explanation:

Let i represents the number of calories eaten by the infant.

We have been given that Alexandria ate eighteen hundred calories. Alexandria ate at most two hundred fifty calories more than twice the number of calories her infant sister ate.

Two hundred fifty calories more than twice the number of calories her infant sister ate can be represented as .

As Alexandria at most calories more than her infant sister, so total calories eaten by Alexandria will be less than . We can represent this information in an inequality as:

Therefore, the inequality represents the given situation.

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
