Which number line can be used to find the distance between (4, –1) and (8, –1)? A number line going from negative 2 to positive
8 in increments of 1. Points are at 4 and 8. A number line going from negative 2 to positive 8 in increments of 1. Points are at negative 1 and positive 4. A number line going from negative 2 to positive 8 in increments of 1. Points are at negative 1 and positive 8. A number line going from negative 8 to positive 2 in increments of 1. Points are at negative 8 and negative 4.
A number line going from negative 2 to positive 8 in increments of 1. Points are at 4 and 8.
Step-by-step explanation:
A number line is a straight line with numbers placed at regular intervals. Since the distance between two points (4, –1) and (8, –1) is needed to be found, they have the same y coordinate therefore they lie on the same line. To determine the distance between the two points a number line going from - 2 to + 8 in increments of 1. Since the x coordinates of the two points are 4 and 8, on the number line points 4 and 8 are marked.
From the number line, the distance between the two points = 8 - 4 = 4 units
34.5=4h+7c (34.5-7c)/4=h Put h= (34.5-7c)/4 into another equation 30.5=8h+3c 30.5=2(34.5-7c)+3c 30.5=69-14c+3c 11c=38.5 c=38.5/11 Put c=38.5/11 into one of the equations to calculate the h.
