Answer:
C and F
Step-by-step explanation:
Answer:
4 parameters are necessary to specify all solutions and correspond to the number of free variables of the system.
Step-by-step explanation:
Remember that the number of free variables of a system is equal to m-rank(A) where m is the number of unknowns variables and A is the matrix of the system.
Since the system is consistent and the rank of the matrix is 3 then echelon form of the augmented matrix has two rows of zeros.
Then m-rank(A)=7-3=4.
Answer:
13
Step-by-step explanation:
2x+2-3x-15>0
-x+13>0
-x>0-13
x>-13/-1
x>13
Hey there! I'm happy to help!
To find the distance between two points, you find the difference between the x values, square that, find the difference between the y values, square that, add the two numbers you got, and then find the square root.
We find the difference between the x values.
-7-2=-9
Square it.
-9²=81
We find the difference between the y-values.
5--3
5+3=8
We square it.
8²=64
We add the numbers we got.
81+64=145
We square root.
√145≈12.04
This formula comes from the Pythagorean Theorem! Now you can find the distance between any two points! Have a wonderful day! :D
