"A closed, or shaded circle is used to represent the inequalities greater than or equal to ( ) or less than or equal to ( ). ... An open circle is used for greater than (>) or less than (<)."

The first equation would have the line going from 1 to -2, as in only  those are less than 9 when adding 7. It would be an open circle, as there is no "less than or equal to" line underneath the sign. X would then be proven to be anywhere from 1 to any negative number.

For the second equation, it has 8 multiplied by x to equal greater than or equal to 64. (Closed circle) 8x8 equals 64, so it means that x cannot be lesser than 8. The closed circle line would go from 8 to 10, X proven to be anywhere from 8 to any larger positive number.

Hope this helped!

the solution is h=10 because you add 9 to each side of the equation.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
