He amount of carbon dioxide (in pounds per 15,000 cubic miles) released by a certain suv depends on its fuel efficiency according to the formula
w = 33x2 − 2145x + 43,000 (12 ≤ x ≤ 33)
where x is the fuel efficiency of an suv in miles per gallon. according to the model, what is the fuel efficiency of the suv with the least carbon dioxide pollution?
x = mi per gallon

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

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
