Answer: The second graph, counting from the top.

Step-by-step explanation:

We have inequality:

-2r + 3 ≥ 19

We can isolate r in this inequality, and get:

-2r ≥ 19 - 3 = 16

-r ≥ 16/2 = 8

Now we change the sign, this also changes the direction of the greater or equal than a sign:

r ≤ -8

So we will have that our graph must start at r = -8, and include all the numbers that are smaller than -8. (including the 8)

This graph is the second one.

so, im t trying to find the original price and sale price of a book for example and the amount of discount is 2.80 dollars and t
aliya0001 [1]

Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price.

60% of x = 2.8

Simply means: 60/100 * x = 2.8

You solve for x, which comes out to $4, which is your original price.

I do believe that it's one of the bisected ones. bisect is the line that splits the middle and D is definitely wrong. So that should narrow it down. So I would go with A or B. Sorry if I didn't help much but it's better than having no clue.

Mrs Smith has 12 times as many markers as color pencils the total number of markers and colored pencils is 78 how many markers d
Ainat [17]
Let the colored pencil amount be p.
Then this is the equation:
12p+p=78
Simplifying, we can see that
13p=78
Divide both sides by 13 to get
p=6

Since there are 12 times as many markers as colored pencils, there are 72 markers.
