5x+6 + 9x+2=360
5x+9x= 360-6-2
14x÷14=352÷14
x=25.14
Please, you need to help yourself by looking up the meaning of these terms: mean, median, mode, range FIRST. How else will you know what you're looking for?
Example: Find the mean of the integers 34 33 35 33 32 35 34 32. To do this, just add them up, count how many you have, and then divide your sum by that count.
Example: Find the median of the integers 34 33 35 33 32 35 34 32. First, arrange these integers in ascending order: 32 32 33 33 34 34 35 35. Second, count them: I see 8 integers. Third, find the median: It's the average of the middle two integers: (33+34)/2 = 33.5
Answer:
No it is not a function because the 10 in the input is repeated twice (the arrow is connected to 2 numbers)
D= {7, 9, 10}
R= {7, 9, 8, 10}
The pairs are (7, 7), (9, 9), (10, 8), (10, 10)
I’m pretty sure B because 1/4 divided by 1/2 equals 1/2 and that the only one that has a model that has 1/2 but don’t take my word for it
Answer:
x^2+7x+12
Step-by-step explanation:
(x+3) (x+4)
FOIL
first: x*x = x^2
outer: 4x
inner: 3x
last: 3*4 =12
Add them together
x^2 +4x+3x+12
x^2+7x+12
