Answer 1

Answer:

so looks like they want you to solve each of them first, then plot them on the number lines.

1) x+8 >= 18

subtract 8 from each side

x >= 10

so for this one you would plot the point (a closed circle, since it's greater than or equal to) on the ten, and draw an arrow pointing to the right

2) x-1 > 6

add 1 to each side

x > 7

for this one you would plot an open circle on the 7 and draw an arrow to the right

3) -7+x >= -8

add 7 to each side

x >= -1

for this one you would plot a closed circle on the -1 and draw an arrow to the right

4) x-1 <= 3

add 1 to each side

x <= 4

for this one you would plot a closed circle on the 4 and draw an arrow to the left
