Just say if a lb cost $2.17 divide 2.17 by 4 which is 0.5425 and 0.5425 times 3 = 1.6275 and 2.17 + 1.63 which is rounded = 3.7975
Answer:
Step-by-step explanation:
You have to know how negative exponents "work" to understand this concept.
because if you want to make a negative exponent positive you put what the exponent is on under a 1. It follows then that you can go backwards from that and rewrite positive fractions with negative exponents.
8x > = -64
x > = -64/8
x > = -8
10x < 60
x < 60/10
x < 6
-8 < = x < 6
Slope = (y2-y1)/(x2-x1) = (2-0)/(12-4) = 2/8 = 1/4
