Can someone help me out with these questions ?

Which compound inequality can be represented by the graph below?

steposvetlana [31]

Answer:

The answer to your question is: letter D

Step-by-step explanation:

The interval graph is (5, 9] , open five, nine close. As an inequality this interval is:

5 < x ≤ 9

a) Letter A is incorrect because it suggests that two sections in the graph must be shaded and in this graph there is only one section shaded.

b) Letter B is incorrect because in the graph we observe that before 5 there must be a parenthesis because the point is open and the point in 9 is shaded so it must be follow by a ].

c) Letter c is alos incorrect because it suggests two sections shaded in the graph and it shows only one.

Frank bought 6 pens and 3 highlighters in the school store and paid $21 for the whole purchase. His friend, Andy, paid $19 for 2

Answer:one pen = $1.50

Step-by-step explanation:

See picture for the math if that helps

Using p for pens, h for highlighter,

A for first equation

B for second equation

I used equation A to reduce to a usable substitute by dividing all by 3

And then isolating “h”.

Now substitute the value of “h” into equation B and solve for “p”

P=$1.50

To check your work, substitute p ($1.50) into equation B and solve for “h”

h=$4.00

Now substitute the p and h values into either equation A or B and solve, they equal the numbers given
