9+9+10+10=38 feet
your perimeter is 38 feet
Answer:
x=-4
Step-by-step explanation:
Divide both sides by 1/4
(x+12)=2 (2 divided by 1/4 =8)
(x+12)=8
Subtract 12 from both sides
x=-4 (parenthesis disappears after 12 is subtracted)
In statistics, 'r' represents the correlation coefficient. The sample correlation coefficient, also known as r, R, or Pearson's r.'r' represents the linear relationship between two variables. It measures the direction and strength between two variables. It is also defined as co-variance of variables divide by the product of standard deviations.
Given the sample correlation coefficient value r is equal to 0.
It means there is no linear relationship between the body temperature and head circumference
Answer:
1
Step-by-step explanation:
since the 2 functions equal each other:
-2x + 3 = 4x - 9
add -2x to both sides
3 = 6x - 9
add 9 to both sides
12 = 6x
divide by 6
2 = x
you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway
-2(2) + 3
-4 + 3
-1 = y
Now we'll find x + y, input them and it's 2 + (-1), which is 1
