1. x is less then or equal to -1 or x is greater then or equal to 5.

2. x is greater then -4 and x is less than or equal to -1

The reason it is equal to or not is because above the original number there is a dot. If it is not filled in, it is considered open. This would leave it as greater than or less than. If it were filled in, it would be considered closed. Leaving it as greater than or equal to or less than or equal to.

Find the slope of the line passing through the points (-6, 6) and (4. – 7).

postnew [5]

Answer:

$\displaystyle -\frac{13}{10}$

Step-by-step explanation:

To solve this problem, first you have to use the slope formula of $\displaystyle \frac{y_2-y_1}{x_2-x_1}$ .

y2= (-7)

y1=6

x2=4

x1(-6)

Solve.

$\displaystyle \frac{(-7)-6}{4-(-6)}=\frac{-13}{10}=\boxed{-\frac{13}{10}}$

Therefore, the correct answer is -13/10.

Samantha sends her son, Barry, to a preschool center on certain days. The cost of preschool is $45 per day along with a fixed mo

Hatshy [7]

Answer: Option D

D. 880 = 45d + 70; 18 days

Step-by-step explanation:

We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.

We also know that a total of $ 880 was paid last month

To write an equation that represents this situation, let us call d the number of days that Barry attends school

So the cost was:

$45d + 70 = 880$

Now we solve the equation for the variable d

$45d= 880-70$

$45d= 810$

$d= \frac{810}{45}$

$d= 18\ days$

The answer is the option D
