Weegy: FOIL (First Outside Inside Last) = 2x(2x) + 2x(-3y) + (-3y)(2x) + (-3y)(-3y) = 4x^2 + (-6xy) + (-6xy) + (9y^2) = 4x^2 - 12xy + 9y^2

You drive a car that holds 15 gallons of gasoline. Your car uses 0.03 gal per mi. Which equation best represents this information? A. y = 0.03x + 15 B. y = 0.03x - 15 C. y = -0.03x + 15 D. y = -0.03x - 15

Weegy: c) y = -0.03x + 15, best represents this situation. User: The temperature was 65 degrees at daybreak. Then it dropped 2 degrees per hour until dusk. If x is the number of hours since daybreak, this equation represents the temperature during the day: y = -2x + 65 OR y = 65 - 2x. Use the equation to predict the temperature 6 hours later. A. 53 B. 63 C. 61 D. 59 Weegy: c. 61 User: Which of the following equations is the slope-intercept form of 4x - 2y = 8? A. y = 2x - 4 B. y = -4x - 8 C. y = 1/2 x + 2 D. y = -2x + 4 (More)

y = 2x - 4 is the slope-intercept form of 4x - 2y = 8.
4x - 2y = 8
-2y = -4x + 8
y = 2x - 4 which is the slope intercept form.
