Answer:
The fifth number is <u>9</u>
Step-by-step explanation:
7 is the mode because it appears the most.
7 has to be the median, so the fifth number could be anything.
7 has to be the mean, so you would do:
7 x 5 = 35
35 - 7 - 7 - 7 - 5 = <u>9</u>
Answer:
x= -2
y=4
Step-by-step explanation:
Since we have an equation set equal to y, we can plug it in for either value of y.
I will be using y= x+6 in this case.
Plug in x+6 for the other equation, so instead of y=-x+2 it will now be that x+6 = -x+2
Now add x to both sides, and that will remove the x on the left side leaving us with 2x+6 = 2
Now, subtract 6 from both sides to get 2x isolated, and you will get 2x= -4
Divide both sides by 2 to get x= -2
Not plug x= -2 in back for the top (or bottom) equation and get that y=4
Hope this helps and isn't too complicated!
Answer:

Step-by-step explanation:

To eliminate the denominators of the main numerator and denominator, we multiply the numerator and denominator of the main fraction by the LCD of all small denominators.
The LCD of x^2, y, x, and y^2 is x^2y^2.
