//Question number 1//

When graphing an inequality there are certain things to keep in mind that make it different from an equation of a line.

Here are some of them:

*You must look out to see whether it will be dashed or solid

*You must know which side of the graph to shade it in

*If they are not in standard form, you have to change them into standard form (THIS ONE MIGHT ACTUALLY APPLY TO A REGULAR EQUATION)

----Basically, the main difference is that in a "normal equation" you have an equal sign while in an inequality you have inequality signs (≤, ≥, <, >)----

//Question Number 2//

------ When using ≤ or ≥ (where they have half the equal sign at the bottom) the line for the inequality would be solid

------ When using < or > (where there is no equal sign- just the inequality sign) the line for the inequality would be dashed

------------------BY THE WAY, I INCLUDED AN ILLUSTRATIO OF AN INEQUALITY GRAPH TO GO ALONG WITH THE 3RD QUESTION----------------

55 is 40% of what number
SCORPION-xisa [38]
You simply put 40 over a hundred and 55 over n (which is the number were trying to find)  so you do cross multiplication. 55 times a hundred and after you get the answer. You divide it by 40 and should get 137.5.

Pls Help Soon as possible
guajiro [1.7K]
The first you can multiply first equation by 2, you will get 16x - 12y = - 40, then add first equation to second

16x - 12y - 16x + 7y = - 40 + 30
-5y = - 10
Y= 2;
Then put y to first equation, because it easier.
8x - 2*6=-20
8x = - 8
X= - 1

Answer is x = - 1, y = 2.

Which of the following events are dependent?
cestrela7 [59]

Answer:

A. Archie and Harris take turns picking yellow- or purple-colored chips from a dish.

C. Lily draws a marble from a bag filled with red and blue marbles, places her selection in a separate bag, and draws from the original bag of marbles again.

Step-by-step explanation:

Two events will be dependent if the first event influences the probability of the second event. If the first event takes something and doesn't put it back, that means the second event can't pull the same roll and the total pool of items changed.

A. Beth and Corrie take turns picking a card at random and recording each outcome. They replace the selected card at the bottom of the pile after each turn.

This option put replace the card, so it is independent

B. Archie and Harris take turns picking yellow- or purple-colored chips from a dish.

No replacement, the event should be dependent.

C. Jared pulls out a sock from the laundry basket containing white and black socks, puts it back, and then draws another sock at random.

This option  put back the pulls, so it is independent

D. Lily draws a marble from a bag filled with red and blue marbles, places her selection in a separate bag, and draws from the original bag of marbles again.

No replacement for the marble taken, each draws probability should depend on the earlier draw result.
