Hey there, Damonealy!
The correct answer should be D since you are talking about multiple amount of data. As you can see, question number 1-3 are talking about the age of a single person but question D is talking about the ages of multiple students which can be used in a statistic.
Thank you for using Brainly.
See you soon!
The simplified version is 25/18
Answer:
The First Option
Step-by-step explanation:
y - 7 = -1/4(x - 4)
Answer:
if you are being asked what the values of the x and y variables are, x=5/2 and y=4
Step-by-step explanation:
In order to solve this problem you will want to isolate one of the two variables in both equations.
I isolated the y variable in both equations so you have:
4x+y=14, when you isolate the y variable, you will get: y=-4x+14
6x-3y=3, same procedure isolate y: 6x-3=3y, now simplify so you only have y: 2x-1=y.
Now that you have the two equations which a common variable, solve them by making the two equations equal to each other like so:
-4x+14=2x-1, now you want to have all the x variable terms on one side and all the constants on the other, you will add "4x" to each side of the equal sign and then add "1" to each side to leave you with: 15=6x
now divide both sides by 6 to obtain your x value: x=15/6 simplifies to 5/2
then plug your x-value into one of the two equations we made earlier:
y=2x-1
y=2(5/2)-1
y=5-1
y=4
now you have calculated the values of your x and y values
6+47=53
53-1=52
that’s all the steps, i hope it helps
