The question is asking to write and equation by using the two variable in the standard form that ca be used to describe the velocity of thecar at different times and base on my calculation, I would say that the answer would be v=4t+39. I hope you are satisfied with my answer and feel free to ask for more
Answer:
C
Step-by-step explanation:
Work backwards. You are given -3 , -30 for C. If you add -3 + 3 and the divide it by 2 , you get 0. If you add 8 + -20 and divide by 2 you get -6 , so the answer is C.
Answer:
you would add 25, 130,55, and 40 all together and than get ur answer
Step-by-step explanation:
x² + 8x + 8 = 0
x² + 8x + 8 + 8 = 0 + 8
x² + 8x + 16 = 8
x² + 4x + 4x + 16 = 8
x(x) + x(4) + 4(x) + 4(4) = 8
x(x + 4) + 4(x + 4) = 8
(x + 4)(x + 4) = 8
(x + 4)² = 8
Answer:
The relationship between two variables is positive when _increase in one causes the increase in the other._______
Step-by-step explanation:
in statistics two variables may be associated or not associated. Normally we define variables as x and y.
If change of x does not affect value of y, then we can say there is no relationship between x and y.
Examples are a person Intelligence quotient and height, a vehicle's weight and its speed, etc.
Sometimes one variable affects another.
Examples are no of hours studied and scores obtained.
Exercises done and health condition etc.
If increase of x causes increase of y then the relationship is positive.
Instead if increase of one variable causes decrease of other variable then the relationship is negative
So
The relationship between two variables is positive when _increase in one causes the increase in the other._______
