A toy company is making a scale model of a 19 foot car. If the miniature car is 4 3/4 inches what is the ratio of the miniature to the car?

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
